Good value but no headers

The board itself is excellent, but remember to buy pin headers separately if you need them.

Perfect for embedded projects

This board works flawlessly with the STM32CubeIDE. Great pinout for my sensor project.

5 FAQ

Q: Are pin headers included in the package?

A: This listing is for the core board only. Pin headers are not included but can be purchased separately.

Q: What programmer do I need for this board?

A: We recommend using an ST-Link V2 programmer for flashing firmware via the SWD interface.

Q: Can I run MicroPython on this?

A: Yes, STM32F103 series supports MicroPython, though memory limits may apply compared to larger boards.

Q: Does this support the Arduino IDE?

A: Yes, this board can be programmed using the Arduino IDE with the appropriate STM32 core installed.

Q: Is the logic level 5V tolerant?

A: No, the GPIO pins operate at 3.3V logic levels. Use a level shifter for 5V devices.
