Install stabilizers, rotary encoders, or OLED panels.
OLED panels must be soldered flush with the pcb or as close as possible. Trim the header pins and do a fit check before moving forward.
If you're using the 3d-printed OLED mounts, use 4 small pieces of wire to connect the panel to the board. Do a fit check with the plate in place.
Trim the rotary encoder pins as short as possible.
Install standoffs into the plate.
For gasket-mount, follow the guide image below. Tighten the screws so the bottom of the screw head is flush with the top of the plate.
Assemble the switches and PCB onto the plate, without soldering any switches.
Remove the yellow tape from the DIP switches.
Configure the DIP switches according to the guide on the LED PCB, shown below. The default firmware has left as the master and right as the slave.
Test the PCB! The LEDs won't work properly on both halves until you finish step 7.
Solder your switches into the PCB. There are many guides online for this, Adafruit has a good reference guide.
Some switches with locating pegs may require clipping to fit with the LEDs. These include the 2u thumb positions, and some of the 1.5u inside positions.
If you're using a regular case/ no case, solder the JA pads together on the LED PCB. If you're using a Full hand frame, solder the 3 JB pads.
Attach rubber feet and/or tenting feet to LED PCB.
Screw the LED PCB onto the standoffs installed earlier.
Optional: Install the frame onto the LED PCB using included screws.
Optional: For the Full hand frames, solder the included jumpers to connect each of the two PCBs. Then install the frame.
