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

Solid Performance
The PSRAM makes a difference for larger projects involving graphics or buffers. Highly recommend.

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.

Q: Can I power it via the VIN pin?
A: Yes, VIN accepts 5V input to power the board independently of USB.
Q: What wireless protocols are supported?
A: It supports Wi-Fi 2.4GHz and Bluetooth 5 Low Energy.
