Power Supply Control

Individual voltage outputs can be disabled using the disable lines on the J5 connector. The J5
connector is a series of four two-pin, 5.08 mm screw terminals accepting AWG 16-14 insulated
wire.

All output voltages are on by default. To turn off a voltage, tie the voltage disable pin directly to
ground. Disabling the +5V output turns off all outputs.
