## Description

This set is intended for those looking to create a differential-drive robot with dual quadrature encoders. Just add two [**micro** metal gearmotors](https://core-electronics.com.au/#) of your choosing (sold separately), a mounting platform such as a [RRC04A 5" robot chassis](https://core-electronics.com.au/#), and a robot controller such as an [Orangutan SVP-324](https://core-electronics.com.au/orangutan-svp-324-robot-controller-assembled.html) (which features inputs for two quadrature encoders) to create a robot capable of closed-loop speed and position control.

This set consists of:

- A [pair of Pololu wheel 42×19mm](https://core-electronics.com.au/pololu-wheel-42x19mm-pair.html)
- A [pair of Pololu micro metal gearmotor bracket extended](https://core-electronics.com.au/pololu-micro-metal-gearmotor-bracket-extended-pair.html)
- Two [encoders for Pololu wheel 42×19mm](https://core-electronics.com.au/encoder-for-pololu-wheel-42x19mm.html)
- Four #2 mounting screws and nuts

**Note:** This set is designed to work with Pololu's 5:1 to 298:1 [**micro** metal gearmotors](https://core-electronics.com.au/#). Motors are not included and must be purchased separately. This encoder will not work with the [1000:1 gear ratio version](https://core-electronics.com.au/1000-1-micro-metal-gearmotor-hp.html) of Pololu's micro metal gearmotors due to the longer gearbox.

This encoder will only work with the Pololu 42×19mm wheel. If you are looking for a higher-resolution quadrature encoder that works with micro metal gearmotors and arbitrary wheels, consider the [magnetic encoder pair kit for micro metal gearmotors](https://core-electronics.com.au/magnetic-encoder-pair-kit-for-micro-metal-gearmotors-12-cpr-2-7-18v.html). We also have versions of Pololu's larger [25D mm](https://core-electronics.com.au/#) and [37D mm](https://core-electronics.com.au/#) metal gearmotors with integrated quadrature encoders.
