Not true I think. 2x $65 plus perhaps still $25 shipping to the US since the 7i92H has two ports. At that price point there are other MESA/PICO solutions that also have a break out board so now you have to factor that into the price too. And it's still USB. Can it handle a 2500 line quadrature encoder? The control is the small part of the overall CNC conversion. I found that buying the CNC Cape for the BeagleBone which all around seemed like the lowest entry cost ultimately wasn't cheaper and it's sitting in a box.
