Motor Wiring?

I'm wiring my hero robot to be controlled by the ezb v4. Attached is a schematic of my v4 showing how it will be hooked up.

My drive motor is a 12v dc to be controlled by an H-bridge.

My steering motor is a 4 wire stepper motor.

Does this look correct?

Thanks Mikeezwiring.pdf


Upgrade to ARC Pro

What H-Bridge are you using for the stepper? A lot of users have had problems getting steppers to work with EZ-B, although @bookmaker32 figured it out with a little additional circuitry. See post 14 in this thread:


It's a L298N H-bridge.


Haven't we had a discussion before on whether or not an H-bridge would work as a motor controller for a stepper motor?... I was under the impression it won't work or was at least a good challenge...

Wouldn't it be easier to just use a basic servo for your steering mechanism?


After further digging I believe you're right @thetechguru. I'll play with it a while and if that doesn't work I'll go the servos.

Thanks to both of you!
