Just played with some samples. Very nice. I'll be using these for the
low power positioning stages that we use. At full power they do get warm
and I would suggest a heatsink is fixed to the chip. None the less, a
really nice microstepping chip without the hassles of requiring to
produce a sine/cosine LUT.
