I got a Pololu controller for a stepper motor. Very happy with the purchase. There is good video documentation, an app with a UI for control, and a Python library for running from command line.
What I’d like to know is which product would best to control up to 8 solenoids with. I just need to control when to send 12v to each of the solenoids. I know a simple bank of relays would do the job but the catch is that I want to do so from a Python app. I found other products out there but I’d rather stick with Pololu because I feel confident that I can get it working without having to go through a bunch of grief.
I think I want something like the Maestro. It does exactly what I want except I only see examples for servos and I don’t see any reference to it being able to drive solenoids so I don’t know if the pinouts will work.
