bracket onto the motor. Make sure it can freely rotate around 180 degrees, and correctly engages the
limit switch. If you feel binding, gently pull the scanner bracket off the motor and remove any
obstructions.
Run the Sweep USB cable out through the small slot on the side of the scanner cover and into the USB
port on the Raspberry Pi.
Connect the limit switch wires to the Raspberry Pie. One lead should go to

header, while the other lead should go to one of the
3V pins
on motor HAT power rail.
