Connector pinout is as follows:
2.1.1.1 Five Volt Modules
If the LCD0821 is used in a PC it is 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 LCD0821 are different as shown in Figure 2-3
below.
If you don't want to modify cable wiring yourself, Matrix Orbital can supply an adapter cable designed to
use with the LCD0821 when it's installed in a PC. The cable is wired as shown in Figure 2-4 below. Note
that this cable does not provide connections for I
