hi,
yes, very easy to use. just the usual interface pins
step, enable, sleep, reset, 3 microstep mode pins.
doesnt need a separate logic supply.
only issue is soldering. if you can solder smd's then this is easy.
it also has fault and home pins that go low if there is a fault and home when at home state of the step table.
vid of a position test at 1/32 microstepping. just simple of loop of 6400 pulses each direction.
