Solid choice
Note that 5V tolerance is on input only, GPIO is 3.3V logic. Make sure your sensors are compatible. Otherwise, it is a great microcontroller board.

Reliable core board
Using it for a robotics project involving motor control. The 72MHz clock speed is sufficient for PWM generation and sensor reading. Highly recommended.

Great for beginners
Works perfectly with STM32CubeIDE. I used this for a university project and it handled all my tasks without issues. Pinout is standard for the Blue Pill style.

Good value board
Chip is genuine, but headers need soldering if you buy the version without them. Performance is solid for the price point. Shipping was fast.

Fast delivery
Packaging was safe, board works as expected. Tested the USB upload functionality and it recognized immediately on Windows 10. No complaints.
Q: Can I power this via USB?
A: Yes, you can power the board via the micro USB port. It regulates the voltage down to 3.3V for the microcontroller.
Q: Is the bootloader pre-flashed?
A: Yes, it comes with a generic bootloader pre-installed, allowing for serial uploads if configured correctly in your IDE.
Q: Is the ST-Link debugger included?
A: No, this listing is for the core board only. You will need to purchase an ST-Link V2 programmer separately for debugging and flashing.
Q: What is the maximum current per pin?
A: Typically 25mA per GPIO pin. Please refer to the official STM32F103x8/B datasheet for detailed electrical characteristics.
Q: Does this support Arduino IDE?
A: Yes, it is compatible with Arduino IDE using the STM32duino board manager package. You may need a USB to TTL adapter for initial bootloader burning.
