MOT-L9110S H-Bridge Dual Channel Stepper Motor Driver Board
US$4.89
This unit comes with two HG7881 Motor Driver boards integrated onto on tiny chip. Using these chips you get a dual channel stepper driver board that can draw individually 800mA and operate from 2.5v to 12v. Send controls from your microcontroller from 3.3v to 5v digital signal lines from the male header pins. The motors run from PWM Signal, you can adjust the duty cycle to modify the speed.

3081-POLOLU Magnetic Encoder Pair Kit for Micro Metal Gearmotors, 12 CPR, 2.7-18V (HPCB compatible)
US$12.53
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. This module is compatible with all of the dual-shaft micro metal gearmotors we carry, including the HPCB versions.

2590-POLOLU Optical Encoder Pair Kit for Micro Metal Gearmotors, 5V
US$13.58
Add quadrature encoders to your LP, MP, or HP micro metal gearmotors (extended back shaft version required) with this kit consisting of two sensor boards, two 3-tooth encoder wheels, and two 5-tooth encoder wheels. The installed system does not exceed the 12 mm × 10 mm cross section of the motors and extends only 5 mm beyond the plastic motor end cap. The 3-tooth wheel provides 12 counts per revolution; using the 5-tooth wheel yields 20 counts per revolution. This version is intended for use at 5 V.
