Good board, needs programmer

The board itself is excellent but remember to buy an ST-Link separately.

Pins were slightly bent

Functionality is fine but shipping packaging could be better. Had to straighten pins.

5 FAQ

Q: Can I power this with 5V?

A: The logic is 3.3V. Some pins are 5V tolerant, but supply voltage should be regulated.

Q: Is an ST-Link programmer included?

A: No, the programmer is sold separately. We recommend ST-Link V2.

Q: Does this board have a USB port?

A: No, this is a minimal system board. You need a USB-TTL adapter for programming.

Q: Does it support MicroPython?

A: Yes, you can flash MicroPython firmware onto the STM32F103C8T6.

Q: What is the EEPROM size?

A: This model does not have built-in EEPROM, but you can simulate it using Flash memory.
