Romi Encoder Pair Kit, 12 CPR, 3.5-18V

Add quadrature encoders to the mini plastic gearmotors on your Romi chassis 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 3.5 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. This kit includes two encoder boards and two magnetic discs.
