Prep the JST Extension cable
Measure the length of the cable from the JST ConnectOR to the USB port.

Build Switch
Cut the positive (Red) cable in half and solder to one of the pins on the slide switch. Remember to slide a small piece of heat shrink to seal the connections.

Battery Cable size
Shorten the battery cable by carefully cutting the wires and then heat shrinking each wire connection.

Use a third hand tool to help keep the wires aligned, solder and heat shrink the wires together.

Reroute Power

For a compact circuit we can reroute the power by soldering the JST Extension cable to the on-board battery connection.

Make sure to leave the onboard power to on.

Pop the slide switch through the cavity for a tight fit

Carefully position the battery on top of the circuit.
