FireBeetle 2 ESP32-S3 AIoT Development Board

SKU: DFR1145

FireBeetle 2 ESP32-S3(N4) is a low-power AIoT development board using Espressif ESP32-S3-WROOM-1-N4 (dual-core 240MHz, 4M FLASH). It supports Wi-Fi/Bluetooth 5.0 + Mesh, AI acceleration for low-compute edge tasks (voice/text/sensor recognition). Key features: rich peripherals, dual power (USB/lithium), multiple programming (Arduino, MicroPython), compact (25.4x60mm, stamp hole). Ideal for IoT/AIoT (home automation, prototyping).

    FAQ

    • Drive multiple servos in the same time
      If you can't drive multiple servos at the same time using the servo library in Basic Tutorial. Please use the ESP32-AnalogWrite library.

    • Hey, what will cause burning error?

      There is no delay or too short delay in Loop.

      The USB cannot be recognized by the PC as some functions are incorrectlly called.

      How to solve

      Press Boot, press RST and release both, then try burning again.
