Standard Blue Pill quality
Exactly what I expected. Genuine chip seems to be used. No issues so far after weeks of continuous testing.

Good value, minor soldering needed
Board works well but headers weren't pre-soldered. Easy to fix though. Performance is solid for university projects.

Perfect for learning ARM
Great board for the price. Works seamlessly with STM32CubeIDE. Pins are clearly labeled and easy to access.
Q: Is the crystal oscillator included onboard?
A: Yes, it comes with an 8MHz crystal oscillator installed on the board.
Q: Does this support 5V logic levels?
A: The MCU operates at 3.3V. While the board accepts 5V power input, GPIO pins are 3.3V logic. Use level shifters for 5V devices.
Q: What debugger works best for this?
A: ST-Link V2 is the most common and cost-effective choice for programming and debugging.
Q: Can I use the Arduino IDE with this board?
A: Yes, you can use the Arduino IDE by installing the STM32duino bootloader package.
