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.
