Great for beginners

Works perfectly with CubeIDE. I was able to blink an LED within minutes of receiving the board. Highly recommend for students.

Okay but fragile

Functionality is fine, but some pins bent easily during shipping. Make sure to handle with care when unpacking.

Good board, minor issue

The board itself is high quality, but it was missing a pinout sticker in the package. Had to download it from the website.
