Input PVIN (12V input) at J3: the recommended wire size is AWG #12, with the total
length of wire less than 2 feet (1 foot input, 1 foot return).
Output VOUT (1V output) at J4: the minimum recommended wire size is AWG #10, with the
total length of wire less than 1 feet (1/2 foot output, 1/2 foot return). A
thicker wire gauge can be required to minimize the voltage drop the wires.
