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.
  • Warning: This board has an USB port called RS232. The data pins of this connector are directly connected to the USART1 pins of the microcontroller. This will not work unless you pit an USB to Serial converter chip in between the microcontroller and your computer.
