Basic Operation

For basic operation, you would need to connect a power source to V(IN). V(IN) is
on the left side of the board, near the input fuse. Polarity is marked on the PCB
(GND, VIN and Ignition). On the cable harness, GND is black, V(in) is red and
Ignition is white. NOTE: Ignition is not needed for basic operation.
Without any further settings, V(out) will generate 12V regulated. V(out) is located
on the right side of the PCB, near the USB connector. On the cable harness,
Yellow is positive and GND is negative.

Configuration jumpers

The configuration header J7 (marked CONFIG) is the most important header in
this board. It is divided in 3 sections:
CONFIG
Output voltage Timing Schemes
