Note: 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 may have a wrong value of resistor on the USB D+ pin. Instead of a 1.5kΩ, it has either a 10kΩ or 4.7kΩ resistor. This can be solved by replacing the resistor with the right value.
