LED Matrices and BackpacksThe 2x mini 8x8 LED matrices are soldered to the backpacks. The pinouts are symmetrical so they can be orientated either way. |
|
Solder LED MatrixInsert 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. |
|
Soldered LED MatrixCheck all of the pins are properly soldered. |
|
Trim PinsThe 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. |
|
Jumper A0Solder the A0 jumper on one of the LEDs matrices to set the address to 0x71. This matrix will be setup as the bottom half of the hourglass. |
