RoboClaw 2x30A Motor Controller (V5D)
The RoboClaw motor controllers from Ion Motion Control (formerly Orion Robotics) can control a pair of brushed DC motors using USB serial, TTL 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 30 A per channel (60 A peak).

The RoboClaw from Ion Motion Control (formerly Orion Robotics) is an efficient, versatile, dual-channel synchronous regenerative motor controller. It can supply two brushed DC motors with 7.5 A, 15 A, 30 A, 45 A, or 60 A continuous (depending on the model) at voltages from 6 V 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.
The RoboClaw has a USB interface that acts as a virtual serial (COM) port, allowing it to be controlled directly from a computer. Several other interface modes are supported by the RoboClaw as well: it can be controlled via TTL serial for use with an embedded system, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), or analog voltages for use with potentiometers or analog joysticks.
RoboClaw versions V5 and above have USB Micro-B connectors; older USB RoboClaws had a USB Mini-B connector.

This RoboClaw 2x30A (V5D) is a slightly improved replacement for the 2x30A (V5). Specifically, the V5D has a protective plastic plate on the bottom and includes a port for optionally connecting a 5 V, 150 mA cooling fan that the RoboClaw will automatically control based on the board temperature. The board size is the same and the locations of the key interface elements (e.g. buttons, terminal blocks, header pins, USB connector, and mounting holes) are unchanged, allowing this version to be used as a direct replacement for the V5 in typical applications.
- Simple bidirectional control of two brushed DC motors
- 6 V to 34 V operating supply range
- 7.5 A to 60 A maximum continuous current output, depending on controller model
- Automatic current limiting reduces duty cycle when motor current is between 1× and 2× the controller’s rated current
- Four communication or control options:
- USB serial interface (virtual COM port)
- Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers
- Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
- 0 V to 2 V (5 V tolerant) analog voltage interface for direct connection to potentiometers and analog joysticks
- Dual feedback inputs for PID closed-loop control:
- Speed or position control with quadrature encoders, up to 19.6 million encoder pulses per second
- Position control with analog encoders or potentiometers
- (Open-loop control with no feedback also available)
- Screw terminals for quick connect/disconnect
- Configurable via pushbutton interface
- Regenerative braking
- Tolerates high-speed direction changes
- Jumper-selectable 5 V BEC
- Battery monitoring and under-voltage cutoff protects batteries from over-discharging
