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.
  • Upper right pin is GND on Blue pill card, but is 5V on Black pill card
  • Reset is on a different pin
  • Some IO pins are om different spots

Arduino IDE

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

BluePill Jumper.png

  • In Arduino IDE,
    • Tools
      • Board "Generic..."
      • Upload method: "Serial..."
      • Port: [the comm port]
