Great information on the NECO drive motor and controller. Any idea what the NECO RPM is? (at the sprocket?)
What speed did you find necessary for the drive motor. (The MAKEMOTORs come in 100 rpm also.)
I am at somewhat of a disadvantage as I am in New York and the boat is in the Virgin Islands -- one of my sons is self-quarantining there. Thus, I can't do the normal things like open the controller box and all and just look for myself.
I was thinking of using Sean's regular motor controller to throw the relays . . . .
You you have a diagram of how you hooked up your pololu driver from PyPilot output to the NECO motor?
And, one more, you don't think Sean's motor controller ( https://pypilot.org/store/index.php?rt=p...uct_id=124 ) would do to drive the NECO drive controller directly? All it must do is switch one of two relays (port and stbd) and one relay (SSR) to power the clutch in "auto-pilot on" mode. I would add an "emergency AP off" switch at the helm to interrupt the clutch power for emergency hand steering. It seems to me that the NECO control could then be left as-is (not any power saving this way, but far simplier!)
I do so appreciate your help and experience.
I would be glad to try out any design you might think is better -- the only difference in our systems is the voltage (your 24 to my 12 VDC)
All my best,
Stay safe,
Kip
The rpm shoud be 17.5 RPM .... look here:

Speak to Sean to see if his reular motor controler will be able to drive the motor and the Clutch, his hydrolic one should do.
Erlier on I had an link ti scratch.pdf with the hoockup to a pololu and the clutch with wich also feeds the series coil. You could also use a rectifier bridge so
I f you dont change the Neco Motor driver it should work with Seans controler, but to make shure , he should have a look at the wiring diagramm of the neco.
To better understandig: the RPI goes to an Arduino Nano and that to the Motor-Driver ----- Seans motordriver has the arduino inside ..... if you keep the Neco motordriver you can use Seans motordriver OR an arduino nano with transistors or mosfets to have the power for the Neco motordriver.
