About Sensor Module¶
The Sensor Module features up-to four universal inputs or outputs on a pluggable terminal block with 1-Wire bus master support. 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 terminals - A on the left, B on the right - are connected to the HARDWARIO TOWER header signals P4/A4/DAC0 and P5/A5/DAC1.
The C pin is in default configuration connected also to the ground GND. It is possible to remove zero-ohm resistor R20 and solder it to the place R21. This way the C signal is directly connected to P7 and can be used as extra input.
The VCC middle pin is possible to control by software. You can enable 3 V on this pin.
