Great MicroPython Support
Flashed MicroPython onto this board easily. It works straight out of the box for my IoT projects. Very happy with the performance.

Perfect for STM32 learning
Clear pinout and good documentation provided by the seller. Using it to learn ARM Cortex-M4 architecture. Highly recommend for students.

Solid development board
Using this for a sensor data logging project. The ADC performance is decent. Only wish the USB connector felt a bit more sturdy.

Good board for the price
Works well for general development. The headers were not soldered which is fine, but would be nice to have an option. Overall solid value.
Q: Does this board support the Arduino IDE?
A: Yes, this board is compatible with the Arduino IDE using the STM32duino package. You can program it just like a standard Arduino.
Q: Does it come with a pre-installed bootloader?
A: Yes, the board comes with a bootloader that allows you to upload code via USB without needing an external programmer initially.
Q: Is an ST-Link debugger included in the package?
A: No, the board does not include an ST-Link debugger. You will need to purchase a separate ST-Link V2 or V3 for debugging if required.
Q: Are the GPIO pins 5V tolerant?
A: Most GPIO pins operate at 3.3V logic levels. Please do not connect 5V signals directly to the pins without a level shifter to avoid damage.
Q: Can I power this board using a LiPo battery?
A: Yes, you can power the board via the VIN pin using a LiPo battery, but ensure the voltage is regulated to 5V before input.
