I posted this on reddit [1][2] and I figured I would share it here as well!
Since many of the new Chamberlin/LiftMaster garage door openers do not have removable light covers, including mine, I decided to make an enclosure to prevent any shorts and keep the PCB properly protected. There are several mounting options as part of the design!
I would suggest you wait to receive your board. Unfortunately, ratgdo is shipping multiple versions of the boards and there is no way to know which one you will get.
