@jafo117 there is no reason it shouldn’t work. AFAIK there has been no one who tried (+documented) such a setup. The drivers on that board are similarly-rated to the A4988 driver chips.
The software driver for the board should listen on a TCP port for commands to emulate a
rotctld process. Current usage of the rotator communications between
satnogs-client and the rotator is two commands. See the code that sends commands to the rotctld port. I’m not sure off hand what else
rotctld does with the attached rotator controller.
All of the above assumes whatever is being send position commands is also able to keep track of its own position in order to act accordingly. This is where the homing switch and the encoder come in. This functionality and hardware interface would need to be included in such a build, the Adafruit HAT handles motor driving only.
