Reliable for prototyping
Used this for multiple prototypes. USB connectivity is stable and bootloader works out of the box.

Perfect for embedded projects
This board works flawlessly with STM32CubeIDE. The pinout is clearly marked and the build quality is solid.

Good value, headers not included
Board works great but comes without soldered headers. Expect to do some soldering work yourself.
