With pluggable spring-cage connector.


  • Buttons.
  • Smart meters.
  • Sensors (photocell, valve position sensors, etc)
  • Digital outputs of other devices.


  • 5-30V Input Voltage.
  • Switching on 1/2 of the reference voltage with hysteresis.
  • Jumper: internal (5V or 24V) or external (5-30V).
  • Possible configurations: Input-Module (GPIOs) or Counter (Interrupts).
  • Available with pin-header or pluggable spring-cage connector.


36.6mm x 29.8mm (1.441in x 1.173in).

Notes on use

When the driver is configured, you can use the Inputs like regular GPIOs on the Raspberry Pi. If it is the first GPIO module on the Pilot the base address would be 55. So the GPIOs are 55-62 (I0-I7).

First, connect the module and configure it using the pilotsetup.sh script.

Exporting the IOs

echo 55 > /sys/class/gpio/export && 
echo 56 > /sys/class/gpio/export && 
echo 57 > /sys/class/gpio/export && 
echo 58 > /sys/class/gpio/export && 
echo 59 > /sys/class/gpio/export && 
echo 60 > /sys/class/gpio/export && 
echo 61 > /sys/class/gpio/export && 
echo 62 > /sys/class/gpio/export

Output current value of all 8 Inputs

cat /sys/class/gpio/gpio55/value && 
cat /sys/class/gpio/gpio56/value && 
cat /sys/class/gpio/gpio57/value && 
cat /sys/class/gpio/gpio58/value && 
cat /sys/class/gpio/gpio59/value && 
cat /sys/class/gpio/gpio60/value && 
cat /sys/class/gpio/gpio61/value && 
cat /sys/class/gpio/gpio62/value
