Easy to use
Plug and play with Arduino IDE. The USB-C connection is very convenient compared to older micro USB boards.

Great for IoT
Works perfectly with Home Assistant. The Bluetooth connectivity is stable and the Wi-Fi range is impressive for such a small board.

Solid choice
Good pinout layout. I wish it had a battery connector included, but otherwise it is a great development board.
