We have been using different configurations to set up our wiring and plan on using a more modular connection type in the future. For testing with a breadboard this will serve as a guide to wiring the device.

Wiring Guide

• GPIO Pin 2, 5V Power / VSS
  • Red Wire
  • Supplies the sensors with power
• GPIO Pin 3, SDA
  • Yellow Wire
  • Serial Data Line for the I2C Protocol
• GPIO Pin 5, SCL
  • Blue Wire
  • Serial Clock Line for the I2C Protocol *GPIO Pin 6, Ground / GND / VDD
  • Black Wire
  • Grounds the sensors
