A small servo (23 x 11.5 x 24 mm) with a weight of 8.6 g, power supply 4.8-6V, maximum torque 1.8 kg / cm (at 6V). It has a connector compatible with the Grove standard. Seeed Studio 316010005

Add quadrature encoders to your 20D mm metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and Hall effect sensors to provide 20 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.

These 20 mm long aluminum adapters convert a 6 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. Pololu 2686
