Wiring Basics
There are several wiring congurations for RoboClaw. Each conguration will have unique wiring requirements to ensure
safe and reliable operation. The diagram below illustrates a very basic wiring conguration used in a small motor system
where safety concerns are minimal. This is the most basic wiring conguration 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.
