The AddKey switch panel can be connected to our CAD-200 board to allow for direct control of the FN-M16P audio module. In addition the board is designed to allow remote switches to be easily connected or allow TTL level outputs (such as from a microcontroller or Arduino etc.) to activate the switches.
