Wiring Basics
There are several wiring congurations for RoboClaw. Each conguration will have unique wiring requirements to ensure
safe and reliable operation. The diagram below illustrates a very basic wiring conguration used in a small motor system
where safety concerns are minimal. This is the most basic wiring conguration possible. All uses of RoboClaw should
include some kind of main battery shut o switch, even when safety concerns are minimal. Never underestimate a
system with movement when an uncontrolled situation arises.
In addition, RoboClaw is a regenerative motor controller. If the motors are moved when the system is o, it could cause
potential erratic behavior due to the regenerative voltages powering the system. The regenerative voltages can cause
problems if a power supply is used for main power. A voltage clamping circuit is recommended to dump the excessive
voltages. See the RoboClaw user manual or Application Notes for voltage clamping setup and wiring diagrams.
R/C Mode
The below wiring diagram is very basic and for use with R/C mode. R/C mode can be used when pairing RoboClaw with a
standard R/C receiver. R/C mode can also be used with a microcontroller and using servo pulses to control RoboClaw. The
RoboClaw supplies power to the R/C system. If the R/C receiver used, has its own power the 5V pin on the 3 pin header
must be remove otherwise it will interfere with RoboClaw’s BEC.
