2.1.2 Five Volt Modules

If the display is used in a PC it then becomes tempting to plug a spare power connector into the unit.

Don’t do this! Wiring for the PC power connector and that required for the display are different, as shown

Figure 4: Wiring for 5V Modules

Matrix Orbital can supply an adapter cable designed for use with the display when it’s installed in a PC.

The cable is wired as shown in the Figure below.

NOTE This cable does not provide connections for I
