RoboClaw 2x30A Dual Channel Motor Controller Data Sheet User Regulated Power Output RoboClaw provides regulated power (BEC) for user devices. A high efficiency switching regulator supplies 5VDC at up to 3 Amps. This voltage can be used to power external sensors, encoders, MCUs and other electronics. The regulated user power is automatically current limited and thermally protected. Main Battery The peak operational input voltage depending on the model can be up to 34VDC, 60VDC or 80VDC.

RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Control Interface The RoboClaw uses standard male pin headers with 0.100” (2.54mm) spacing. The pin headers are ideal for use with standard servo cables and other popular interface connectors. The table below list the pins and their respective functions. All pins are 5V tolerant and output 3.3V for compatibility with processor such as Raspberry Pi and Arduino.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Logic Battery (LB IN) The logic circuit of RoboClaw can be powered from a secondary battery wired to LB IN. A logic battery will prevent brownouts when the main battery is low or under heavy load. The positive (+) terminal is located at the board edge and ground (-) is the inside pin closest to the heatsink. Encoder Power (+ / -) The pins labeled + and - are the source power pins for encoders.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Main Battery Screw Terminals The main power input can be from 6VDC to 34VDC on a standard RoboClaw and 10.5VDC to 60VDC or 80VDC on an HV (High Voltage) RoboClaw. The connections are marked + and - on the main screw terminal. The plus (+) symbol marks the positive terminal and the negative (-) marks the negative terminal. The main battery wires should be as short as possible. ! Do not reverse main battery wires or damage will occur.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Control Modes RoboClaw has 4 main functional control modes explained below. Each mode has several configuration options. The modes can be configured using Motion Studio or the built-in buttons. Refer to the RoboClaw User Manual for installation and setup instructions. RC Using RC mode RoboClaw can be controlled from any hobby RC radio system. RC input mode also allows low powered microcontrollers such as a Basic Stamp to control RoboClaw.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Wiring Basics There are several wiring configurations for RoboClaw. Each configuration will have unique wiring requirements to ensure safe and reliable operation. The diagram below illustrates a very basic wiring configuration used in a small motor system where safety concerns are minimal. This is the most basic wiring configuration possible.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Wiring Safety In all system with movement, safety is a concern. This concern is amplified when dealing with higher voltages. The wiring diagram below illustrates a properly wired system. An external main power cut off is required (SW1). The external cut off can consist of a high amperage mechanical switch or a contactor.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet Logic Battery An optional logic battery is supported. Under heavy loads the main power can suffer voltage drops, causing potential logic brown outs which may result in uncontrolled behavior. A separate power source for the motor controllers logic circuit, will remedy potential problems from main power voltage drops. The logic battery maximum input voltage is 34VDC with a minimum input voltage of 6VDC.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet RC Control Setup 1. Wire the RoboClaw Solo, power supply, motor and RC hardware as show in the RC wiring diagram in this datasheet. 2. Additionally, it is recommened to wire safety hardware as show in the Safety Wiring section of this datasheet. 2. Connect a micro USB cable between the RoboClaw Solo and a computer with Motion Studio installed. The USB connection does not power the RoboClaw, a power supply must be connected.
RoboClaw 2x30A Dual Channel Motor Controller Data Sheet 10. To complete the setup for RC mode click Device in the menu at the top of the application and then click on Write Settings. The settings are now saved to the Solo. 11. Disconnect the Solo from Motion Studio by clicking Disconnect Selected Unit in the upper left-hand side of the application. The USB connection can then be removed from the Solo. 12. The robot or other system can now be operated remotely with the RC transmitter.
