ESP32-C6-WROOM-1-N8

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, and distributors flag it Not For New Designs — the recommended current code is ESP32-C3-MINI-1-H4X. Selection advice: for new designs specify the H4X (or the -40 to +105 °C H4) 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.

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.

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-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.

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.

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.

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.
