LED Matrices and Backpacks
The 2x mini 8x8 LED matrices are soldered to the backpacks. The pinouts are symmetrical so they can be orientated either way.
Solder LED Matrix
Insert the pins from the 8x8 LED matrix through the top of the backpack. Ensure the LED matrix is installed correctly and flush with the PCB. A stick vise can help keep the components in place while soldering.
Trim Pins
The pins are long and need to be trimmed in order to fit inside the 3D printed enclosure. Use flush cutters to shorten the pins from the LED matrix.
