The Quadrature Shaft Encoder is fully compatible with the existing Squarebot 2.0 and
3.0 models. Use the following wiring conguration to ensure that the Encoders count “up”
when the robot drives forward, and “down” when the robot moves in reverse. Reversing
the placement of the wires will cause the Encoders to count in the wrong direction (-2, -4,
-6 instead of 2, 4, 6); failing to place the wires in the correct ports will result the Quadrature
Encoder behaving as an original Encoder, or not at all.
