Great for MicroPython

Flashed MicroPython instantly. Wi-Fi connection is stable and the PSRAM helps with larger scripts.

Perfect Nano Form Factor

Love the ESP32-S3 power in the Nano size. USB-C is a huge plus for my modern setup.

Good board, pinout slightly different

Works well but check the pinout diagram before wiring sensors as it differs from standard AVR Nanos.
