Good value board

Solid build quality and fast shipping. I wish it included a USB cable in the box, but otherwise great.

5 FAQ

Q: Does it come with headers soldered?

A: Usually shipped with pin headers unsoldered to allow for custom setup and breadboard use.

Q: Is the 5V pin output or input?

A: It can be used as an input for external power or as an output powered via the USB connection.

Q: What debugger do you recommend?

A: We recommend using an ST-Link V2 debugger for SWD programming and debugging.

Q: Does this support Arduino IDE?

A: Yes, you can program it using Arduino IDE with the appropriate STM32 board packages installed.

Q: Can I drive motors directly?

A: No, please use a motor driver module. GPIO pins cannot handle the high current required for motors.
