• DO I use the four vacant inputs to connect the four sensors? I hope somebody who had successfully installed these sensors will share the detailed steps. Thanks
  • They use JST leads which have 3 lines. Vcc, Gnd and Analogue.

    Obviously the Vcc goes to your 5V rail, Gnd goes to the ground rail and the Analogue goes to analogue points on the APM/IMU. If you look at the APM/IMU board two analogue point have all three connections next to one another.
