This pcb includes a transformer on the board, which gives you the option to power it using a 6v to 30v battery from your chamberlain or liftmaster battery instead of a micro USB. Note, you can still use a microUSB if you prefer doing that. Although the electrical wires from the circuit board going out to the battery are included, you will have to figure out how to connect them to your chamberlain or liftmaster battery - this will depend on your model, but a few suggestions are to use alligator clips, quick splice connectors or simply tie or solder them onto the battery.

Please see v2.0 in another ad if you don't want a transformer.
