Perfect for learning embedded systems

Works great with ST-Link. The pinout is standard and easy to breadboard. Highly recommend for students.

Pinout labeling could be better

Had to check the wiki to confirm pin functions. Silkscreen is a bit small but functional.

Good value but needs programmer

Board is solid, just remember it doesn't have USB upload built-in. You need an external programmer.

Reliable core board

Using this for a drone controller project. Very stable under load and fast processing.

5 FAQ

Q: Does this include an ST-Link programmer?

A: No, this is just the board. You need to purchase a programmer separately.

Q: Is this 5V tolerant?

A: No, the logic level is 3.3V. Using 5V on GPIO pins may damage the microcontroller.

Q: Can I power this via micro USB?

A: No, this board lacks a USB interface. Use the 5V and GND pins for power.

Q: Does it support MicroPython?

A: Yes, you can flash MicroPython firmware onto it using a compatible programmer.

Q: What debugger do you recommend?

A: We recommend the ST-Link V2 for best compatibility and ease of use.
