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.micro-metal-geara.jpg

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
