Assembly of this project is pretty straightforward. Most of special instructions revolve around the RGB shield assembly. Because the Metro M4 Express Airlift is still a Metro M4, you will need to cut one of the traces and add a wire.

You may want to consider reversing the direction of the screw terminal blocks so the wire isn't up against the wall of the mount,.

You can follow assembly instructions for the RGB shield in our 32x16 and 32x32 RGB LED Matrix guide.

To assemble, you will want to start by adding the heat-set inserts into place where the Metro M4 Express Airlift will be mounted.

Carefully inset the heat-set inserts using a heat-set tool or jig.

Carefully line up the Metro M4 Airlift onto the heat-set inserts. Make sure the power jack is able to go through the hole. It's a little tight, so you may need to use a sharp knife to carve away any excess filament.

Install the four screws to secure the Metro M4 Airlift.

Next, snap the two halves together.

Install the four magnetic screws into the short ends of the RGB Panel.

Once you have your RGB Shield soldered up, connect the power wiring harness to the screw terminals on the RGB Shield.

Place the shield onto the Adafruit Metro M4 Express Airlift.

Connect the ribbon cable that came with the panel between the Panel and the shield.

Next, using a level, mount it onto the wall using some long wood screws. Do not over-tighten.

Attach your ribbon cable and one of the power connectors to your RGB Panel.

With all the wires connected, carefully place any extra long wires into the side without the board.

The RGB Matrix Panel works by using the special magnetic screws that come with the panel to magnetically stick to the wall mounting screws. You may need to loosen the wall mount screws a bit if it's not sticking well in all four corners.

Once that is done, connect power. It should say connecting... followed by the last message that was stored in your feed value.
