I've used this driver with both the Moonlite external motor controller (with temp sensor) and with the Pegasus UPBv2 to control the stepper directly and both worked great.
Note that in neither case can you be certain that you are getting an absolute position with the focuser unless you build a "reset" script to rack all the way in and reset the step count to zero. Not difficult to do, but worth knowing if you are fussy about recording focus positions for flats etc.
