Description
Built-in encoder
Average output up to 198.6 pulses per revolution
Brass faceplate has two mounting holes threaded
Long D profile metal output shaft (0.354"/9.0 mm)
The 6V 100:1 155RPM Micro Metal Gearmotor w/ Encoder comes with a built-in encoder which measures the motor's speed in real time. The average output number of pulses can reach up to 198.6 pulses per revolution. The motor has a long (0.354"/9.0 mm) D profile metal output shaft that is compatible with the 42x19mm and 32x7mm dimensions of the Pololu wheel. The brass faceplate has two mounting holes threaded for M1.6 screws (1.6mm diameter, 0.35mm thread pitch), or you can use the mounting bracket or extended mounting bracket which are specifically designed to securely mount the gear motor while enclosing the exposed gears.
Works as advertised, though it's a shame that all of the encoder options for these micro metal gear motors have the wires coming out vertically rather than horizontally, so one will either lose clearance and have the wires handing down under the robot, or have to (typically) cut a hole in the mounting plate to clear the the encoder board and wires. Coming out horizontally would be quite a bit nicer. (I realise this is feedback to the manufacturer, not RobotShop.)

Encoder is always a nice feature
The same tiny motors that you are used to but with the additional utility of an encoder. Often only a single phase is required for simple projects.

Very nice little motor using it to make electric shifters for my road bike
Well built little servo motor for price

Good Motor
This is a good product. The board and wire connector helps a lot. The board has an LED to show it is working.
