Nope, and at that price, I'm really not likely to. OK, maybe there's a convenient way to talk SPI to the thing, but what worries me is that it will "autonomously execute movement commands". I.e. You'll have to send it a protocol packet with step count and presumably a feedrate, then it's off like a dog after a stick, IIUC. For small steppers, I'd rather spend half the money on a BED: https://www.sparkfun.com/products/12859 which admittedly will only do 2A, even if you stick a heatsink to the top of the chip. But at least it responds to each step input given. (I'm not sure if that's the Allegro chip which Gene shies clear of, though.)
