Features & Applications

The LCD 64x32 logic boards are used for mounting LCD 64x32 SmartSwitches or SmartDisplays into panels and system assemblies. The 2 switch versions are also used in the SmartSwitch Dev Kits as demonstration platforms for the SmartSwitch and SmartDisplays.

The application notes should be used in conjunction with the LCD 64x32 data sheet which has the LED, LCD,
