Due to parts and components going obsolete and becoming unavailable, the 1057_3B has moved to a new processor that is not supported under Phidget21. If you're using our old libraries you must upgrade to Phidget22 before you can make use of this Phidget.

The PhidgetEncoder Highspeed interfaces with any 5V quadrature encoder. A quadrature encoder is the most commonly used feedback device for a DC or stepper motor. With an encoder, you can keep track of how far your motor has turned, which then allows you to control the position and velocity in your code. This Phidget connects to your computer via USB.


  • Works with all 0-5V quadrature encoders - read incremental encoders with line driver, open collector, or push-pull output circuits
  • Read at speeds of up to 500,000 quadrature cycles per second
  • Power Saving Options - You can turn it off via software when it's not turning. While disabled, this board draws 55mA of current.
  • High compatibility - Select between four different pull-up/pull-down resistor configurations in our API
  • Reports a timestamp in milliseconds for each position change event, for easy velocity calculation.
