Remarks

  • 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.
  • Note: This board has solder bridges SJ3 and SJ4. These connect pin 35 and 36 respectively and provide power on devices that have power pins there. On boards with devices that have PF6 and PF7 exposed on these pins, these bridges are cut.
