1.4.3. Quadrature Encoder Input
Attach the Quadrature Encoder as shown. Do not ground the GND line elsewhere. Connect either
the 3.3V or 5.0V as required by your sensor. DO NOT CONNECT THE 3.3V OUTPUT TO THE 5V
OUTPUT. Some encoders may have an Index pin. Talon supports counting the rising edges on the
Index rail so that robot controller can react to it. However wiring index is not required for decoding the
position and velocity of the encoder.
