Flashed the bootloader and works with Arduino IDE seamlessly.

5 FAQ

Q: Is the bootloader pre-installed?

A: Some batches come with it, but we recommend flashing the latest STM32duino bootloader for best compatibility.

Q: Does this include an ST-Link programmer?

A: No, this board is sold without a programmer. You will need to purchase an ST-Link V2 separately.

Q: Is this the Jiangke Da edition specifically?

A: Yes, this is the Jiangke Da Science & Technology Association Edition as listed.

Q: What debugger interface does it support?

A: It supports SWD and JTAG debugging interfaces via the dedicated header pins.

Q: Can I use 5V logic on the pins?

A: No, the GPIO pins are 3.3V logic. Applying 5V may damage the microcontroller.
