Good clone, works as expected
It's a generic version of the popular Blue Pill board. Functionality is identical to the original for my blinky tests and sensor readings. Just ensure you have a proper ST-Link programmer.

Perfect for learning embedded systems
This board is exactly what I needed to start my journey with ARM Cortex-M3. The pinout is clearly labeled, and it works flawlessly with the STM32CubeIDE. Great value for the price.

Great for motor control projects
Using this to drive a BLDC motor controller. The PWM outputs work perfectly, and the 72MHz clock speed handles the calculations without lag. Highly recommended.

Best budget development board
I bought three of these for my university project. They are reliable, cheap, and powerful enough for most control applications. Shipping was fast too.

Solid hardware, minimal documentation
The board itself is high quality and the soldering is clean. However, you need to know your way around STM32 development as there is no included manual. Recommended for intermediate users.

Reliable for industrial prototyping
We used these for initial prototyping before moving to custom PCBs. The stability is impressive for the cost. No issues with voltage regulation or reset circuits.
Q: Does this board come with a USB-to-TTL converter or ST-Link programmer?
A: No, this listing is for the core board only. You will need to purchase an ST-Link V2 or USB-to-TTL adapter separately to program and power the device.
Q: Does this support the SWD debug interface?
A: Yes, the board exposes the SWDIO and SWCLK pins on the header, making it fully compatible with SWD debugging using tools like ST-Link, J-Link, or DAPLink.
Q: What is the maximum current draw for the 3.3V output pin?
A: The onboard regulator can typically supply up to 200mA, but we recommend keeping the load under 100mA for stable operation and to prevent overheating the regulator.
Q: Is this compatible with the Arduino IDE?
A: Yes, you can use this board with the Arduino IDE by installing the appropriate STM32 board support package via the Board Manager. You may need to set the bootloader jumpers correctly before uploading.
Q: Can I power this board directly via the 5V pin?
A: Yes, the board includes an onboard voltage regulator. You can supply 5V to the 5V pin, and it will regulate it down to 3.3V for the microcontroller. Alternatively, you can feed 3.3V directly into the 3.3V pin.
