Sensor Interface
The pin headers J1, J2 and J3 constitute the sensor interface. It can be e.g. used with Encoders or Hall sensores. J3 is the selector between differential sensor interface (J2) or single ended sensors (J1). Connecting sensors is only allowed to one of the two pinheaders, the other one has to stay unconnected. In the figure below the jumper configuration of J3 to enable one or the other type of sensor interface is depicted.
