Reasonably Priced 100A Motor Controllers

I have two of these boards and they both have the same result no function on channel 2 channel one works fine. I’ve even tried a second Arduino i’ve also tried moving the pins from channel one which works to channel 2, and it will not work

Maybe your controller has same issue? https://www.xsimulator.net/communit...0a-motor-controllers.17638/page-9#post-258442

Also make sure that the limits of the pot does not turn off the motor. Check in SMC3 config tool it motors are on. Also tripple check ground connections.

Yep mine had the same problem. Soldered in a jumper wire and it’s all good now. cheers

i ordered up some new drivers for a different project and guess what channel 2 is not working !

Sadly it appears somebody has robbed the quality control failures and is distributing them to suppliers !

however the fix is pretty straightforward

we drilled the through hole and fitted a copper wire / rod

Its so sad that a great little driver board has been a target of dishonesty
