2. Setting up LITOS' hardware
Overview of LITOS' control unit
The control unit of LITOS can be ordered pre-assembled. However, before the first use, you need to connect the PCB with the LED matrix and in a second step load the LITOS software onto the control unit.

In rare cases, the OLED display might not be already attached to the PCB. In this event, please plug the OLED display into the headers in the middle of the PCB.
-
Connect the flat ribbon cable (16 pins) to LITOS. On the LED matrix there are two connectors for the flat ribbon cable. Pay attention to connect the cable to the input connector. It is typically located on the left side if the arrows on the back of the LED matrix point to the right and/or to the top.

Next, connect the power cable to the matrix and the PCB (cable with red / black wire). In order to insert it into the screw terminal on the PCB, we recommend that you bend one of the metal fork teeth so it dosn't cause troubles when you screw the other theeth in the screw terminal. Alternativly you can cut off the metal fork at the end of the cable and then strip the two wires a bit. The red cable end has to be connected to “M+“, whereas the black cable to “M-” on the screw terminal.

Connect LITOS with the wall power adapter.
Now, the software can be loaded onto LITOS (flashing).
