Great for Beginners
Easy to set up even if you are new to microcontrollers. The Type-C port is a nice modern touch compared to older boards.

Perfect for IoT Projects
Works seamlessly with the Arduino IDE. The Bluetooth 5.0 connectivity is stable and the range is better than expected for such a small board.

Driver Issues on Windows
Had trouble installing drivers on Windows 11 initially. Once sorted out, the board works fine, but the setup process was frustrating.

Fast BLE Connection
Connection range is impressive. I used this for a home automation sensor and it hasn't dropped connection once in a week.
