A pair of compact N20 gearmotors with built-in encoders, ideal for small-scale robotics projects. These popular motors pack power and precision into a tiny 12×10mm gearbox profile, making them perfect for differential drive robots, mini rovers, and space-constrained builds.
Each motor includes a 31.5:1 gear ratio for a good balance of speed and torque, plus a 3mm D-shaft for easy wheel mounting. The included cables make wiring straightforward.

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
