GP SWITCH INTERFACE BOARD Provides a 128 switch matrix to connect and decode static switches. The software driver returns both the switch position as a row and column and hex value of the key position and the state as ON or OFF. Depending on your specific application and switch requirements, it is possible to reduce the number of discrete diodes required to eliminate switch ghosting. Check with our support staff for technical details and tips on how to organize and wire your switches.
