For completeness we provide the main board pins used to implement this sensor board:

  • Power Pins (Output Only)
    • 3.3V : Constant 3.3V Output from LDO used to power the Sensors
    • S_GND : Electronically-controlled Ground Pin (ground switch through IO12)
  • Other Sensor/Control Pins (Input/Output)
    • IO38 & IO39 : I²C Control (SCL) & Data (SDA) Line (Already Pulled-up) for controlling GPS
    • IO5, IO6 & IO7 : ADC compliant pins for getting analogue readings from Analogue Sensor Port 1, 2 and 3 respectively
