Arduino IDE compatible
Easy to setup with the STM32duino bootloader. Makes prototyping much faster compared to writing raw register code.

Great for beginners
Works perfectly with ST-Link. I used this for my university embedded systems project and had no issues uploading code.

Good value board
The board itself is high quality, but note that the pin headers are not soldered. You will need to do that yourself.

Pinout confusing
Board works fine but the silkscreen labeling is a bit small. Had to refer to the datasheet frequently to find specific pins.

Fast shipping
Arrived well packaged. Solid build quality and all pins tested functional. Highly recommend for hobbyists.
Q: What programmer do I need to upload sketches?
A: We recommend using an ST-Link V2 programmer for the best compatibility and debugging features.
Q: Does this board support the Arduino IDE?
A: Yes, this board is compatible with the Arduino IDE when you install the STM32duino board package.
Q: Is 5V logic tolerated on the GPIO pins?
A: No, the GPIO pins operate at 3.3V logic levels. Applying 5V directly may damage the microcontroller.
Q: Are the pin headers included and soldered?
A: The board typically comes without headers soldered. You will need to purchase and solder them separately.
Q: Can I power the board directly via the USB port?
A: Yes, you can power the board via the micro USB port, which provides 5V to the onboard regulator.
