This components are used to build the 4 controller modules that form the input side of the physical ''Zynthian User Interface''. Each controller embed an incremental rotary encoder and a switch, so 4 wires (A,B,SW,GND) are needed for connecting it. | This components are used to build the 4 controller modules that form the input side of the physical ''Zynthian User Interface''.
