Aha!, they've cunningly slaved an Ardy on there for GRBL support. The electronics are built down to a cost - with some significant compromises.
Like I said - kit-in-a-box. I don't think it'd suit everyone.

Edit 2:

Not just closed-loop steppers, but integrated driver, too. I reserve judgement until I read up..... 2NM, 36V supply, 250kHz max input frequency, NEMA 23 size. Think the supply side of things will limit performance but... kit-in-a-box.
Those two things right there are a flashing beacon to stay away.!!
