Interfacing/powering cfag320240c-fmi-t


New member
I have CFAG320240C-FMI-T LCD display.
First of all I would like to know if I need to use +5v inverter (CFAICCFL1)?

Do I put 5V volt to the pin2 (Vdd)?
What voltage needs to be fed to PIN3 (V0)? 24V?

I know how to connect to data lines, but I'm worried about the power lines. I don't want to burn this thing ;-)

What is the purpose of the 3-wire cable hanging on the back panel if everything is supposed to be connected through pin header?

The cable on the back goes to the CFAICCFL1. It runs the backlight.

For this display, there is a control on the back that can adjust Vo, so you can leave that pin open, and juct adjust the contrast using the control.

Vdd = 5v, Vss = Gnd
