Basic Micro’s RoboClaw motor controller can control a pair of brushed DC motors using serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 15 A per channel (30 A peak).
The RoboClaw from Basic Micro is an extremely efficient, versatile, dual channel synchronous regenerative motor controller. It supports dual quadrature encoders and can supply two brushed DC motors with 5 A, 15 A, or 30 A continuous (depending on the model), and twice as much peak, at voltages from 6 to 30 V.
The RoboClaw features dual quadrature decoding capability. A built-in PID routine can be used for closed-loop speed control, maintaining motor speeds even if the load varies, or the encoder counts and speeds can be read directly from the RoboClaw for use with an external control system.
Several interface modes are supported by the RoboClaw. It can be controlled via TTL serial for use with an embedded system or a PC with a serial adapter, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), or analog voltages for use with potentiometers or analog joysticks.

1 A separate logic supply is needed if the main power source is over 17 V.
Basic Micro has written an Arduino library for the RoboClaw (21k zip) that makes it easy to interface these motor controllers with an Arduino. The library comes with several example sketches that demonstrate different methods of controlling the RoboClaw. (We have updated the library to work with version 1.0 of the Arduino environment.)
