Ideal for university projects

Used this for my final year project. The stability is impressive, and the breadboard compatibility makes prototyping very easy. Highly recommended for students.

Great value but needs a programmer

Excellent hardware for the price. Just remember this specific kit does not include the ST-Link programmer, so you will need to purchase one separately to upload code.

Classic blue pill alternative

Functions just like the classic 'Blue Pill' boards but seems to have better soldering quality on the headers. No issues flashing firmware via SWD.

Perfect for beginners

This board is exactly what I needed to start learning embedded systems. The pinout is clearly labeled, and it works flawlessly with the Arduino IDE and STM32CubeIDE.

Good batch for our workshop

Bought ten of these for our community workshop. Nine worked out of the box, one had a slightly bent pin which we fixed easily. Overall great quality control.

Robust and reliable

I have been using this board for various sensor integration tests. It handles 3.3V logic perfectly and the USB boot mode is very convenient for debugging.

5 FAQ

Q: What is the maximum current this board can supply on the 3.3V pin?

A: The onboard regulator can typically supply up to 200mA, but we recommend keeping your load under 150mA for stable operation and to prevent overheating.

Q: Can I power this board directly with a 9V battery?

A: It is not recommended to connect 9V directly to the 5V pin as it may exceed the regulator's limits. Please use a regulated 5V source or a USB connection.

Q: Is this board compatible with the Arduino IDE?

A: Yes, it is fully compatible. You can install the STM32 board package via the Board Manager in Arduino IDE and select the 'Generic STM32F1 series' option.

Q: Does this board come with an ST-Link programmer included?

A: No, this entry kit includes only the development board itself. You will need to purchase an ST-Link V2 or compatible programmer separately to upload code.

Q: Does this support MicroPython?

A: Yes, you can flash MicroPython firmware onto this STM32 board. You will need to use a tool like dfu-util or an ST-Link to upload the appropriate .bin file.
