Preface
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. This user manual will go through general features. The NKK

General Logic Control Features
The LCD 64x32 logic boards are PCB’s that have mount positions for one or more LCD 64x32 SmartSwitches
or SmartDiplays. The switches/displays can be mounted directly on the logic board or on a socket mounted on
the board. One or two switch boards are the most common but logic boards with other configurations are
available as well as custom designs. They have some “glue logic” for converting the select lines and switch
scanning to serial, and therefore many logic boards can be daisy-chained via 14-pin ribbon cables. The switch
numbering is according to their order in the daisy-chain, where the switch number one is on the logic board
connected directly to the controller.
There are three types of LCD 64x32 logic boards; RGB pushbutton, RGB display, and RGB compact.

1.
IS Prefix.
2.
The Logic Board base part number. The first number is the quantity of switch positions on the board.
The second number is the version.
3.
No code = No socket for IS switches.
C = Sockets are soldered to the PCB for IS switches.
4.
No code = No IS switches.
IS15… = The logic board is populated by the IS Switches.
Logic boards can be customized based on customer requirements.
