I have seen them but no experience . Looks like this setup was designed for the cnc market as well as 3d printing . Looks like that set up or sister product would run a router or small mill with no problem.
Kind of a mid ground rice wise between a ramps and a gecko drive I like the fact motor power is directly connected to the driver board no where near the controls circuits. Control card as 10x that of the polo drivers but a lot more to the board a huge heat sink and lots of reserve power If i read correctly the boards will handle 4 amps. (that may be a cnc version)
You may want to check some of the cnc hobby forums for reviews.
Seems like a good effort in documentation at least.Company Information
