Jumpers are provided for disconnecting the power from the Developer Board and for disconnecting the power from the g20.
You may wish to remove the Developer Board power jumper and shut off the power to the board in order to diagnose a problem
that may be caused by the board. The g20 will continue to receive power.
You may also want to remove the g20 power jumper and then connect an amperometer to the jumper’s two pins to measure the
current through the g20.
