Pin labels are small
Board works fine but the silkscreen printing for the GPIO numbers is hard to read without a magnifier.

Excellent for IoT Prototyping
This board works flawlessly with MicroPython. The USB-C connection is stable and the pinout is standard.

Great hardware, average docs
The board itself is high quality. I wish the included wiki had more examples for the AI features.
