Connecting the Servo pHAT and Servos

The Servo pHAT is the interface for both the pan-tilt rig and the Qwiic sensors. The pHAT plugs in so that it's stacked directly above the Pi Zero.

The servo cables for the pan-tilt rig will run underneath the mounting plate, under the board and pop out on the opposite side. The bottom servo plugs into ROW 0 and the top servo into ROW 1.

The brown wires should be on the pins closest to GPS board. See the image below.

The Qwiic cable that connects the GPS Board to the Servo pHAT through the time of flight sensor becomes obscured by the cover plate. It’s best to plug in the 50mm Qwiic cable to the GPS Board Qwiic connector facing the center of the cover plate at this point (don't plug it into the time of flight sensor quite yet).
