DRV8835 Dual Motor Driver Carrier

This tiny breakout board for TI’s DRV8835 dual motor driver can deliver 1.2 A per channel continuously (1.5 A peak) to a pair of DC motors, and it supports two possible control interfaces for added flexibility of use: IN/IN and PHASE/ENABLE. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering up to two small, low-voltage motors. The carrier board has the form factor of a 14-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1 inch perfboards.

Solarbotics RM2 (High-Power Motor for GM2/3/8/9)

This high-power brushed DC motor fits in the GM2/3/8/9 series of gear motors, offering approximately 3 times the speed, twice the torque and quadruple the power-draw. Retrofitting the gear motor is easy – just remove the motor retainer strap, transfer the pinion gear, and reinstall – that’s it.
