Good but needs care
Board works well but be careful with 5V tolerance on GPIOs. They are 3.3V logic. Otherwise satisfied.

Great Value Core Board
Bought this for a university project. Works flawlessly with STM32CubeIDE. Pin headers are well soldered.

Perfect for Embedded Projects
The UART download feature saves so much time. No external programmer needed for basic sketches. Board quality is excellent.
