ESP32-S3-WROOM-1-N8 is Espressif’s general-purpose Wi-Fi + Bluetooth LE module — ESP32-S3 dual-core Xtensa LX7 up to 240 MHz, 802.11b/g/n, Bluetooth 5 LE with mesh, PCB trace antenna, 8 MB SPI flash — for connected products with edge processing: HMI panels, sensor gateways, and TinyML vision (the S3’s vector instructions accelerate neural-network workloads). The ‘N8’ denotes 8 MB flash without PSRAM; variants with octal PSRAM exist for frame-buffer-heavy applications. Selection advice: the on-module 40 MHz crystal and pre-tuned RF are certified as a module, which cuts wireless certification cost and time versus a chip-down design — the main reason to choose the module over the bare ESP32-S3. For external-antenna designs order the -1U variant (U.FL connector) instead; the PCB antenna needs keep-out clearance that the -1U does not. Active at distribution in tape-and-reel. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-WROOM-32E-N4 is a Wi-Fi and Bluetooth module from Espressif Systems with 4 MB Flash and an integrated antenna — the default connected-device module for IoT products. The module form factor is the procurement advantage: pre-certified RF with antenna, Flash and crystal in one part, which removes RF design and certification cost from your project. Selection advice: the N4 code denotes 4 MB Flash — match your firmware size against it, and step up to larger-Flash variants if your application needs OTA partitions plus application code. Confirm your regional certification requirements for the module. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP8266EX is a 2.4 GHz Wi-Fi system-on-chip from Espressif Systems in a QFN-32 package — for compact connected devices. This is the chip that made Wi-Fi connectivity commodity-priced: a complete Wi-Fi SoC at a price point that put wireless into every sensor node. Selection advice: the EX is the chip-level part for custom modules and designs — for faster time to market, consider the pre-certified ESP-WROOM modules instead of designing the RF section yourself. Confirm your Flash size and certification needs before choosing chip versus module. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C3-MINI-1-N4 is Espressif’s compact RISC-V Wi-Fi + Bluetooth LE module — ESP32-C3 32-bit RISC-V single-core up to 160 MHz, 802.11b/g/n, Bluetooth 5 LE, PCB antenna, 4 MB flash in a 13.2 × 16.6 mm footprint — for cost-sensitive connected devices: smart home, sensors, and BLE accessories. Lifecycle note: Espressif marks this N4 ordering code NRND (not recommended for new designs) in the module datasheet v2.2, and distributors flag it Not For New Designs — the recommended current code is ESP32-C3-MINI-1-N4X. Selection advice: for new designs specify the N4X (or H4X for the -40 to +105 °C grade) instead; the N4 remains relevant only for sustaining existing builds. The RISC-V core with 400 KB SRAM keeps the bill of materials minimal for simple Wi-Fi/BLE tasks that do not need the S3’s dual-core performance. 3.0–3.6 V supply; the -1U connector variant suits metal-enclosure designs. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Texas Instruments CC2642R1FRGZR is a SimpleLink Bluetooth 5.2 Low Energy wireless microcontroller in the 7×7 mm VQFN-48 (RGZ) package, built on a 48 MHz Arm Cortex-M4F with 352 KB flash, 80 KB SRAM and an ultra-low-power sensor controller. Radio performance includes 6.9 mA RX, up to +5 dBm TX output, -105 dBm sensitivity on LE Coded PHY and 0.94 µA standby with RTC and RAM retention. Its advantage for procurement is single-chip BLE: MCU plus 2.4 GHz radio plus protocol stack in ROM eliminates the separate wireless module, cutting BOM cost and board area for connected sensors, locks and beacons. Selection advice: the RGZ VQFN-48 exposes 31 GPIOs — confirm pin count against your peripheral mix before committing, since smaller CC2642R package variants trade GPIOs for size; and budget RF layout effort (antenna, matching, crystal) because a chip-down design needs the RF front-end engineering a pre-certified module would spare you. Evidence: TI CC2642R datasheet (SWRS194) confirms Cortex-M4F, 352 KB flash, Bluetooth 5.2 LE and VQFN-48. Confirm packing and date-code requirements in your RFQ — we reply within 24 hours.

RN4871-I/RM128 is a Microchip Bluetooth Low Energy module, Bluetooth 5 certified, in a shielded 9 × 11.5 mm surface-mount package with integrated chip antenna — the drop-in BLE link for cable-replacement, sensor beacons and phone-to-device apps. The ASCII command interface over UART is the selection point: a host MCU talks to the module with plain text commands instead of wrestling a BLE stack, and the on-board scripting engine even allows hostless operation for simple beacon or GPIO tasks. Selection advice: the -I suffix denotes the industrial -40 to +85 °C variant (the -V suffix is the narrower -20 to +70 °C commercial grade) — match the suffix to your operating environment; the RM128 shielded version simplifies certification versus the unshielded RM130. Supply range is 1.9 to 3.6 V, so a single Li-ion cell or 3.3 V rail feeds it directly. Parameters verified against the Microchip RN4870/71 datasheet (DS50002489) and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

BG95-M3 is a Quectel multi-mode LPWA cellular module supporting LTE Cat M1, Cat NB2 and EGPRS fallback with integrated multi-constellation GNSS (GPS/GLONASS/BeiDou/Galileo/QZSS), in a 23.6 × 19.9 × 2.2 mm LGA package — the global-band tracker and meter module for asset tracking, smart metering and wireless POS. The triple-mode fallback is the selection point: Cat M1 (588 kbps down / 1119 kbps up) where operators support it, NB2 for deep-indoor reach, and quad-band EGPRS as the safety net in regions where LTE-M/NB-IoT coverage is thin. Selection advice: this is the global M3 variant with the widest band set — confirm your carrier Cat M1/NB-IoT bands against the Quectel band list before committing, since regional BG95 variants differ. The built-in ARM Cortex-A7 running ThreadX plus DFOTA lets application logic run on-module for ultra-low-power designs; budget for three antennas (main, diversity, GNSS) on the PCB. Supply is 3.3 to 4.3 V (3.8 V typical), -35 to +75 °C operating (-40 to +85 °C extended). Parameters verified against Quectel BG95-M3 specifications. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SIM7600G-H is a SIMCom LTE Cat 4 module in a 30.0 x 30.0 x 2.9 mm LCC+LGA form factor (135 pads) — for global-band M2M designs that need one hardware variant across many regional networks, subject to local band and carrier checks. Per SIMCom's SIM7600G/SIM7600G-H Hardware Design V1.00, it covers LTE-FDD B1/B2/B3/B4/B5/B7/B8/B12/B13/B18/B19/B20/B25/B26/B28/B66 and LTE-TDD B34/B38/B39/B40/B41, WCDMA B1/B2/B4/B5/B6/B8/B19 and quad-band GSM, with LTE Cat 4 throughput of 150 Mbps downlink and 50 Mbps uplink, HSPA+ fallback at 42 Mbps / 5.76 Mbps, a GNSS engine (GPS, GLONASS and BeiDou) and a single 3.4 V to 4.2 V supply (3.8 V recommended). Selection advice: choose the G-H variant when the same product ships to multiple regions; choose a regional variant such as the SIM7600E-H when the deployment is fixed to one regional band plan, because module band support — not host software — decides where each variant can register. Band support alone does not grant network access or certification in any country; confirm the operator and regulatory approvals for your target market before production.

CC2530F256RHAR is a 2.4 GHz Zigbee and IEEE 802.15.4 system-on-chip from Texas Instruments in a 40-pin VQFN package, with 256 KB Flash — for Zigbee mesh nodes, smart-home devices and industrial sensor networks. The integrated 8051 MCU plus radio in one chip is the selection point: a complete Zigbee node without a separate microcontroller, on the mature Z-Stack. Selection advice: the F256 code denotes 256 KB Flash — the CC2530 ships in 32/64/128/256 KB variants that are not firmware-compatible, so match the full CC2530F256RHAR code. The RHAR suffix denotes VQFN-40 on tape and reel. For new Zigbee designs, also evaluate current-generation TI wireless MCUs; for existing Z-Stack products, match the code exactly. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C6-WROOM-1-N8 is an Espressif module based on the ESP32-C6 32-bit RISC-V single-core SoC (up to 160 MHz) with Wi-Fi 6 (2.4 GHz), Bluetooth 5 (LE) and IEEE 802.15.4 (Zigbee 3.0 / Thread) radios, 8 MB QSPI flash and PCB antenna — the Matter-ready wireless module for smart-home devices, sensors and Thread border-router designs. The triple-radio integration is the selection point: one module covers Wi-Fi 6, BLE and 802.15.4, so Matter-over-Thread and Matter-over-Wi-Fi products share a single hardware platform. Selection advice: the N8 suffix denotes 8 MB flash — check whether your firmware plus OTA partition fits, since smaller-flash C6 module variants exist. It is pin-to-pin compatible with the ESP32-WROOM series, which simplifies migration from ESP32/ESP32-C3 boards, but RF layout and antenna keep-out still follow the Espressif module datasheet. The module carries FCC/CE/IC/MIC/KCC/NCC certifications. Parameters verified against the Espressif ESP32-C6-WROOM-1 datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TLSR8258F512ET32 is a Telink BLE 5.1 wireless SoC with BLE Mesh and multi-antenna AoA/AoD support, 512 KB flash, 64 KB SRAM, in QFN-32 — the low-cost mesh-networking chip for smart lighting, ESL tags, beacons and HID devices. The integrated BLE Mesh stack on a 32-bit proprietary RISC core (up to 48 MHz) is the selection point: lighting and sensor nodes run a full mesh without an external network processor, with hardware AES/AES-CCM and ECC acceleration for secure provisioning. Selection advice: this is BLE 5.1, not 5.4 — verify the Bluetooth version claim against the Telink datasheet when comparing with newer 5.4 SoCs. The F512 denotes 512 KB flash (the F1K variant doubles it for larger stacks); the T32 suffix is tape-and-reel QFN-32 packing. Supply is 1.8 to 3.6 V, -40 to +85 °C, with 10 dBm TX and -93 dBm RX sensitivity, so coin-cell designs are realistic — but budget RF matching and antenna design per the Telink reference layout. Parameters verified against the Telink TLSR8258 datasheet (DS-TLSR8258-E18) and Mouser listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-S3-WROOM-1-N16R8 is an Espressif ESP32-S3 MCU module — dual-core 240 MHz Xtensa LX7 with vector instructions for AI acceleration, 16 MB Quad SPI flash, 8 MB Octal SPI PSRAM, 2.4 GHz Wi-Fi 4 and Bluetooth 5.0 LE, integrated PCB antenna, native full-speed USB 2.0 OTG, 18 × 25.5 mm SMD module, -40 to +65 °C (R8 variants), 3.0 to 3.6 V supply. The 8 MB PSRAM is the selection point: the highest-tier WROOM-1 configuration for display frame buffers, camera pipelines and edge-AI inference (the same variant used in Espressif’s ESP32-S3-EYE dev kit). Selection advice: N16 = 16 MB flash and R8 = 8 MB Octal PSRAM — for the largest memory configuration confirm this full code, since N8R2 and other variants share the WROOM-1 footprint. For an external-antenna design choose the -1U variant instead of the PCB-antenna -1. Note the 8 MB PSRAM variant specifies -40 to +65 °C operating range. Espressif lists this code as Active. Evidence: Espressif ESP32-S3-WROOM-1 datasheet and DigiKey/LCSC listings confirm N16R8 configuration, Wi-Fi 4 + Bluetooth 5.0 LE, PCB antenna and -40 to +65 °C. Match the full ESP32-S3-WROOM-1-N16R8 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C3-WROOM-02-N4 is an Espressif ESP32-C3 module — 32-bit RISC-V single-core at 160 MHz, 4 MB SPI flash (N4), 2.4 GHz Wi-Fi 4 and Bluetooth 5.0 LE, integrated PCB antenna, 18 × 20 × 3.2 mm SMD, -40 to +85 °C, 3.0 to 3.6 V supply. The RISC-V core is the selection point: lower cost and lower power than dual-core Xtensa modules for sensor nodes, smart-home and Matter/Thread bridges, with USB Serial/JTAG and TWAI (CAN-compatible) peripherals built in. Selection advice: N4 = 4 MB flash — for larger firmware or OTA partitions confirm the N4 code, since WROOM-02 variants share the footprint with different flash sizes. For dual-core AI or PSRAM workloads choose the ESP32-S3 series instead. Espressif lists this code as Active. Evidence: Espressif ESP32-C3-WROOM-02 datasheet and DigiKey listings confirm RISC-V, 4 MB flash, Wi-Fi 4 + Bluetooth 5.0, PCB antenna and -40 to +85 °C. Match the full ESP32-C3-WROOM-02-N4 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Nordic documents NRF24L01P-T as an official order code in the nRF24L01+ product specification — a 2.4 GHz GFSK transceiver, 2 Mbps air data rate, SPI interface, 4×4 mm 20-pin QFN package, tray packing. The 2 Mbps GFSK link with SPI control made this the default low-cost 2.4 GHz transceiver for RC toys, wireless keyboards and sensor links. Note: Nordic marks the nRF24 series Not recommended for new designs — for new designs qualify a current-generation 2.4 GHz transceiver before committing the BOM; for existing builds, remaining stock is lot-dependent. Selection advice: the -T suffix denotes tray packing — match the full NRF24L01P-T code. Parameters verified against the Nordic official product specification. Send quantity and date-code requirements with your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DA14531-00000FX2 is an ultra-low-power Bluetooth 5.1 system-on-chip from **Renesas Electronics** (not onsemi — the industry list misattributed the vendor) in a 24-pin FCGQFN package, for battery-powered BLE beacons, wearables and sensor nodes. It integrates an Arm Cortex-M0+ with 32 kB OTP, 48 kB retainable RAM, AES-128 hardware encryption and a buck/boost DC/DC, transmitting at 3.5 mA and receiving at 2.2 mA with -94 dBm sensitivity. Selection advice: the FX2 code is the FCGQFN-24 package on tape and reel; the OG2 code is the WLCSP-17 variant. Longevity to 2034 per Renesas. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-S3-WROOM-1-N8R8 is an Espressif Wi-Fi + Bluetooth 5 (LE) module built around the ESP32-S3R8V system-in-package, with 8 MB of quad-SPI flash and 8 MB of octal-SPI PSRAM in a 25.5 x 18 mm SMD footprint with an on-board PCB antenna. Its advantage is memory headroom without an external RAM chip: the octal PSRAM absorbs frame buffers, LVGL display assets and TensorFlow Lite Micro model weights that stall on 2 MB-class modules, while the dual-core Xtensa LX7 at up to 240 MHz keeps Wi-Fi, BLE and application threads on separate cores. Designers gain a drop-in upgrade path — footprint and pinout match the rest of the ESP32-S3-WROOM-1 family, so a board laid out for any N8R2/N16R8 variant accepts this one without re-spin. Selection advice: note the ambient rating is -40 to +65 C on the R8 variants (not the -40 to +85 C of non-R8 modules); Espressif qualifies 85 C operation only with PSRAM ECC enabled and other stated conditions, so confirm your thermal enclosure against the datasheet note before committing to industrial use; the 1U twin (ESP32-S3-WROOM-1U-N8R8) is identical except for the external-antenna connector. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-S3-WROOM-1U-N8R8 is the external-antenna twin of the ESP32-S3-WROOM-1-N8R8, built around the ESP32-S3R8V SiP with 8 MB quad-SPI flash and 8 MB octal-SPI PSRAM in an 18 x 19.2 mm SMD module with a U.FL-class antenna connector instead of the on-board PCB antenna. Its advantage is RF flexibility: a connector lets the designer pick a high-gain or metal-enclosure-friendly antenna, recover range in shielded housings, and pass modular certification once while swapping antenna SKUs per region. Electrically and mechanically it is the same module as the N8R8, so firmware, PSRAM timing and power budgets carry over unchanged. Selection advice: the -40 to +65 C ambient rating of the R8 variants applies here too — 85 C needs PSRAM ECC and the other datasheet conditions; choose the 1U when the enclosure is metal or the range target exceeds what a PCB antenna delivers, and pick the on-board-antenna 1-series when BOM simplicity matters. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C6-WROOM-1-N4 is an Espressif Wi-Fi 6 (802.11ax) + Bluetooth 5.3 (LE) + IEEE 802.15.4 module built around the ESP32-C6 RISC-V SoC, with 4 MB quad-SPI flash in an 18 x 25.5 mm SMD footprint with an on-board PCB antenna. Its advantage is three radios on one low-cost module: Wi-Fi 6 with TWT for battery-friendly infrastructure links, BLE 5.3 with mesh and high-power 20 dBm mode, and 802.15.4 for Thread 1.3 and Zigbee 3.0, so one SKU covers Matter border-router and end-device designs. The RISC-V single core at 160 MHz plus 512 KB HP SRAM keeps protocol stacks off the application budget that an ESP32-C3 would strain. Selection advice: pick the N4 when 4 MB flash fits your OTA partition plan — the N8 variant doubles flash for larger dual-bank OTA images; the 1U twin swaps the PCB antenna for an external connector at 18 x 19.2 mm. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C6-WROOM-1U-N8 is the external-antenna variant of the ESP32-C6-WROOM-1-N8, built around the ESP32-C6 RISC-V SoC with 8 MB quad-SPI flash in an 18 x 19.2 mm SMD module with an antenna connector. Its advantage combines the full tri-radio stack (Wi-Fi 6, BLE 5.3, 802.15.4) with antenna choice: metal enclosures, gateway boxes and long-range Thread/Zigbee links all benefit from a proper external antenna where a PCB antenna would detune. The 8 MB flash doubles OTA headroom versus the N4, useful for Matter firmware with large crypto and commissioning stacks. Selection advice: this is the variant to pick for Thread border routers and Zigbee coordinators in real housings; for cost-optimized end devices with a plastic case, the on-board-antenna 1-series usually suffices. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C5-WROOM-1-N4 is an Espressif dual-band Wi-Fi 6 (2.4 + 5 GHz) + Bluetooth 5 (LE) + 802.15.4 module built around the ESP32-C5HF4, with 4 MB quad-SPI flash and no PSRAM in an 18 x 27.5 mm SMD footprint with an on-board PCB antenna, rated -40 to +85 C. Its advantage is 5 GHz in the ESP32 module line: dual-band operation dodges congested 2.4 GHz spectrum in dense deployments, while the RISC-V core at 240 MHz and CAN FD support target industrial gateways. The N4 is the entry point of the C5 family for firmware that fits 4 MB with OTA. Selection advice: step up to N8R8 (8 MB flash + 8 MB PSRAM) or N16R8 (16 MB flash + 8 MB PSRAM) when display buffers, TLS session caches or larger OTA banks exceed 4 MB; the 1U series mirrors these options with an external-antenna connector. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C5-WROOM-1-N8R8 is built around the ESP32-C5HR8 with 8 MB quad-SPI flash and 8 MB quad-SPI PSRAM, adding memory headroom to the dual-band Wi-Fi 6 + BLE + 802.15.4 module in the same 18 x 27.5 mm PCB-antenna footprint, rated -40 to +85 C. Its advantage is running richer stacks on the newest Espressif radio: 8 MB PSRAM holds LVGL frame buffers and Matter/Thread state that the N4 cannot, while 8 MB flash supports comfortable dual-bank OTA for 5 GHz firmware images that run larger than 2.4 GHz-only builds. Selection advice: choose N8R8 over N4 when your application needs display, camera, or large crypto/OTA budgets; choose N16R8 only when 8 MB flash proves insufficient, since PSRAM is already 8 MB here. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C5-WROOM-1-N16R8 is the top-memory variant of the C5 module family, built around the ESP32-C5HR8 with 16 MB quad-SPI flash and 8 MB quad-SPI PSRAM in the 18 x 27.5 mm PCB-antenna footprint, rated -40 to +85 C. Its advantage is maximum in-module storage for dual-band designs: 16 MB flash supports A/B OTA banks plus factory fallback, large certificate stores and multilingual display assets, while 8 MB PSRAM keeps the RISC-V core fed on graphics and protocol workloads. Selection advice: this is the safe pick when firmware size is still growing mid-project; if the final image stabilizes well under 8 MB, the N8R8 saves cost with identical PSRAM; do not confuse the R8 (8 MB PSRAM) with the R2 (2 MB PSRAM) variants when ordering. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ESP32-C5-WROOM-1U-N4 is the external-antenna variant of the Espressif dual-band Wi-Fi 6 (2.4 GHz + 5 GHz) + Bluetooth 5 (LE) + 802.15.4 module, built around the ESP32-C5HF4 with 4 MB quad-SPI flash and no PSRAM in an 18.0 x 21.2 x 3.3 mm SMD footprint rated -40 to +85 °C. Where the WROOM-1 listings on this site use an on-board PCB antenna, the 1U routes RF to a connector (or module pin ANT2) — the pick when the enclosure is metal, the antenna must sit on the housing, or a higher-gain external antenna is needed. Per the module datasheet (v1.3, Table 1-2) the default antenna port is ANT1, and ordering the ANT2 port adds a T2 suffix to the code. Selection advice: this N4 is the 4 MB entry point of the 1U line — N8R8 and N16R8 versions add 8 MB PSRAM when firmware outgrows 4 MB; for on-board-antenna designs use the WROOM-1 codes listed separately. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SIM800L is a SIMCom quad-band GSM/GPRS module in an 88-pad LGA package (15.8 × 17.8 × 2.4 mm) — 850/900/1800/1900 MHz 2G voice, SMS and GPRS data for M2M, remote metering and telemetry in regions where 2G networks remain operational. The tiny LGA footprint is the selection point: cellular connectivity in under 16 × 18 mm for designs that still run on GSM infrastructure. Selection advice: this is the bare module, not a third-party development board — antenna, power supply and SIM interface are your design’s responsibility. Network note: operators are retiring 2G in a growing number of regions, so confirm 2G availability in your target market before committing a new design; global connectivity is not implied. Parameters verified against the SIMCom SIM800L hardware design documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
