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: The microcontroller on this board features internal pull-up resistors for the USB data lines. However, this board has an additional pull-up resistor on D+ (R21). This resistor is not needed and violates the USB specification when the internal pull-up resistors are also used. This may cause errors while using USB on this board.
