This product replaces the plastic cap on the back of a VEX 2-Wire Motor 393 with a quadrature encoder. Install this product and connect it to your Cortex Microcontroller via I2C to receive direct feedback from the motor. This encoder provides information on how fast the motor is going, how far it has traveled, and what direction it is moving.

  • Increased feedback from your motors allows for more control.
  • Communicates via I2C via included 4-wire Cable.
  • Not compatible with the PIC Microcontroller.
  • Programming Required! Consult your software provider for details.



Do not over-tighten screws when installing the Integrated Motor Encoder. Over-tightening can affect encoder performance.

Up to (8) I2C devices can be chained together and connected to (1) I2C port on the Cortex Microcontroller.
