Power

The board can be powered with 5V using the USB Type-A connector. There are also a few power related pins.

VIN input pin can be used to power the board with an external source between 7V to 35V. This pin is input into the 5V 500mA onboard regulator.
5V output pin is the 5V regulated output voltage (100mA) from the onboard regulator.
GND pin is the common/ground/0V reference.
