RoboClaw 2x30A (V4)
The RoboClaw motor controllers from Orion Robotics 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, or analog feedback can be used for position control. This version can supply a continuous 30 A per channel (60 A peak).
As of June 17, 2013, we are selling V4 RoboClaw controllers (2×5A, 2×15A, and 2×30A) with upgraded firmware. The new features include position control, current limiting, and support for closed-loop control in RC and analog modes. They are physically the same as the preceding versions.
The RoboClaw from Orion Robotics (formerly Basic Micro) is an efficient, versatile, dual-channel synchronous regenerative motor controller. It can supply two brushed DC motors with 5 A, 15 A, 30 A, or 60 A continuous (depending on the model) at voltages from 6 to 34 V, and it allows for peak currents up to twice the maximum continuous rating.
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. Analog feedback is also supported for closed-loop position control.
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. The RoboClaw 2×60A additionally supports direct computer connections with a USB serial interface (virtual COM port).

Orion Robotics has written an Arduino library for the RoboClaw 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.
