I have focusing device for a telescope. It is just a stepper motor, a controller board and a USB connector.
The controller board burned out and replacement are not available.
I wanted to replace the board with a pololu Multi-Interface Stepper Motor Controller Pololu - Tic T500 USB Multi-Interface Stepper Motor Controller…
However, I would need to change the FW running on the controller so that it “simulates” the interface used by the older board. Is this possible with any of the pololu boards?
