Sensor Module The Sensor Module features two universal inputs on a pluggable terminal block. The terminals can be used as both analog and digital input/output. For example you can connect various external digital, analog or resistive sensors. Also, you can communicate with other devices on a 1-Wire bus.

The two terminal - A on the left, B on the right - are connected to the BigClown header signals P4/A4/DAC0 and P5/A5/DAC1. The other two terminals in the middle are connected to the GND (ground) signal.
