If you don't want to make holes in your backbox by mounting the board with screws, this bracket is an option.
1. Download and 3D print the bracket. Click here if your board is a Rev3 or here if you have a Rev2.
NOTE: The holes in this model are oversized so that they print correctly using my 3D printer. Yours may vary. The holes should be 3.75mm diameter when printed.
2. Use four #8-32 x 1/4" nylon screws to mount the LED OCD Mini board to the bracket.
NOTE: I do NOT recommend using metal screws because they will overlap copper traces on the board and risk shorting if the solder mask were to get a hole in it.
3. There are two threaded holes in the backbox that are intended to secure the backbox to the cabinet. Use the one on the right, along with a leg bolt (or any 3/8"-16 bolt at least 1" long) to secure the backet in the backbox.
You can now continue with the rest of the installation as normal.
