Add quadrature encoders to your micro metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and Hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. These encoders have their pins arranged as through-holes on a 2mm pitch, and wires or 2mm-pitch connectors must be soldered in to use them.

This kit includes two encoder boards and two magnetic discs.
