Magnetic Encoders for Micro Metal Gearmotors, 3081

This kit 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.

This module is compatible with all of the dual-shaft micro metal gearmotors from Pololu, including the HPCB versions.
