The top header is an expansion/output header. They KEY OUT and MS OUT are connected to the LEDs on the
back to indicate whether you're pressing a keyboard or mouse key, respectively. This can be used to connect low-
power LEDs and small motors. The RESET will reset the board when connected to ground. There are also pins for
power through the 5V and GND. The last two pins (PGD and PGC) are used by the factory to program.
The pins broken out through the black female headers are all available in the form of “jumper-wire” connectors to
connect male jumper wires, header pins, stripped wires, or tinned tipped wires.
