Great Minimal Core Board

Compact and fits well on breadboards. Wish it had a built-in USB connector instead of just pins, but otherwise solid.

Good Value but No Debugger

The board itself is excellent quality. Just remember you need an ST-Link programmer separately. Took off one star because the silk screen is a bit faint.

Perfect for Student Projects

Bought this for a university embedded systems course. Works flawlessly with Keil and STM32CubeIDE. Pinout is standard.

5 FAQ

Q: Does this come with a USB cable?

A: No, this is a minimal core board. You need an ST-Link programmer separately.

Q: Can I drive 5V servos directly?

A: No, the GPIOs are 3.3V logic. Use a logic level converter or driver circuit for 5V components.

Q: Is it compatible with Arduino IDE?

A: Yes, you can use the STM32duino package to program it via Arduino IDE.

Q: What is the input voltage range?

A: The logic is 3.3V. You can supply 3.3V directly to the 3.3V pin or 5V to the 5V pin if regulated on board.

Q: Where can I find the pinout diagram?

A: Please check the product description images or visit the manufacturer's wiki for the standard Blue Pill pinout.
