Blue Pill vs Black Pill Pinout
- Warning: The +5V pins on this board are directly connected to the +5V pin of the USB connector. There is no protection in place. Do not power this board through USB and an external power supply at the same time.
- Reset is on a different pin
- Some IO pins are om different spots
Arduino IDE
- Hardware files to support STM32 boards, on Arduino IDE 1.8.x including LeafLabs Maple and other generic STM32F103 boards
- Arduino Alternative - STM32 Blue Pill Programming Via USB
Uploading Code
- FTDI connection to Blue Pill Hub FTDI connector
- FTDI TX (to Blue Pill RX) (PA10 pin on STM32)
- FTDI RX (to Blue Pill Tx) (PA9 pin on STM32)
- Set Switch (or jumper) on Blue Pill module set towards center of card to upload card to board
- In Arduino IDE,
- Tools
- Board "Generic..."
- Upload method: "Serial..."
- Port: [the comm port]
- Tools
- Upload code
- Takes a while
- Set Switch (or jumper) on Blue Pill module set towards edge of card to run
- Press reset button
