Headers J1, J2, J7 and J9 provide three alternatives for LCD interface. The Easy GUI Controller Board ships with a 12-pin low insertion force connector installed in header J2. Headers J1 and J2 are pre-routed with a positive drive voltage variable +17 to +23 VDC . If your display requires a different drive voltage negative or positive , you must supply this voltage externally. Contact us for more info. Also, the LCD signals to the interface headers are CMOS level signals. If your LCD requires TTL signals, contact us for simple board modification instructions.
