Install Corner Brackets
Corner brackets are secured to the four corners on the RGB matrix display. These brackets are secured to the mounting holes. They also fit a sheet of black LED acrylic.

Fitting Corner Brackets
Place the brackets over the corners and orient them so the mounting holes are properly lined up. The side of display should have the brackets with visible mounting holes. These holes are used for securing the button mounting plate.
Installing Feet
Place the foot over the corner brackets and line up the mounting holes. Reference the photo for correct placement.
Secure Feet
Use two M3 x 10mm long screw to secure the feet to the corner brackets. The screws will also fasten into the threaded inserts that are on the display.
Button Wiring
A short 2-wire JST cable is soldered to the arcade button. This is connected to the JST cable that is soldered to the D4 pin on the FeatherWing.
