Good board, USB cable could be better

The board itself is excellent and runs all my code without errors. The included USB cable felt a bit flimsy, but the board makes up for it.

Easy to start with

As a beginner, I was worried about compatibility. This worked right out of the box. The community support for this chip is amazing.

Drivers needed installation

The hardware is fine, but I had to manually install CH340 drivers on Windows 10. Once that was done, it worked fine. Just be prepared.
