Perfect for MicroPython projects

This board works flawlessly with MicroPython. The USB-C connection makes flashing code incredibly easy, and the pinout is clearly labeled. Great value for the price.

Compact and powerful

I was surprised by how much processing power is packed into such a small board. It drives my OLED display and multiple sensors simultaneously with no lag. Highly recommended.

Great for student learning

Bought ten of these for our university robotics club. Students find the transition from Arduino to this STM32 board very smooth thanks to the compatible form factor and strong community support.

Solid performance, minor documentation gaps

The hardware quality is excellent and the 84MHz speed handles my sensor data logging without issues. Would give 5 stars if the included quick start guide had more examples for C++ development.

Good board, steep learning curve for beginners

The board itself is high quality, but if you are new to ARM architecture, be prepared to do some reading. Once set up, it runs very stable. The MicroPython REPL is a lifesaver.

Reliable for industrial prototyping

Used this for a rapid prototype of an industrial controller. The temperature stability and GPIO responsiveness were impressive. Will definitely order more for the final production run.

5 FAQ

Q: What debugger interface does this support?

A: This board supports SWD (Serial Wire Debug) programming and debugging. You will need an external ST-Link V2 or J-Link debugger connected to the dedicated SWD pins.

Q: Are the pin headers soldered onto the board upon arrival?

A: No, the board typically ships with a separate packet of pin headers to allow flexibility in mounting options. You will need to solder them on yourself.

Q: Can I power this board directly with a 5V battery?

A: You can connect a 5V source to the VIN pin or via USB-C. The onboard regulator will step it down to 3.3V for the microcontroller. Do not apply 5V directly to the 3.3V pin.

Q: Does this board come with pre-flashed MicroPython firmware?

A: Yes, most batches come with the latest stable MicroPython firmware pre-installed. However, we recommend checking the version and updating it via the USB drive mode if needed.

Q: Is this compatible with the Arduino IDE?

A: Absolutely. You can use the Arduino IDE by installing the appropriate STM32 board package via the Board Manager. Many standard libraries work out of the box.
