This set is intended for those looking to create a differential-drive robot with dual quadrature encoders.
Note: Micro metal gears are not included in this set.
The encoder will work with any micro metal gears from Pololu ranging 5:1 to 298:1.
This set consists of:
- A pair of 42×19mm wheels
- A pair of gearmotor bracket extended
- Two encoders for the 42×19mm wheels
- Four #2 mounting screws and nuts

Notes:
- 1. The assembled encoder will extend 4.25 mm beyond the back of the motor (it fits entirely within the length of the extended motor shaft).
- 2. Weight of full set. Each encoder board weighs ~0.6 g and each magnet disc weighs ~0.6 g.
- 3. The assembled encoder will extend 5 mm beyond the plastic motor end cap (it fits entirely within the length of the extended motor shaft).
- 4. Weight of full set. Each encoder board weighs ~0.2 g and each magnet disc weighs ~0.3 g.
- 5. Weight of full set. Each encoder board weighs ~0.2 g and each encoder wheel is less than 0.1 g.
