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 is a generic board. There are other variations available with a different microcontroller, like on with an STM32F405RGT6 device.
