I saw this tiny Windows 10 Single Board Computer on the EEVBlog a while back. Not only does it have a quad core Intel Atom processor to run Windows 10, it also has an Arduino co-processor built on the board too. I have not explored the Arduino functionality at this time.
The board comes with Windows 10 installed but you will need your own license. I installed the Mach 4 Hobby version and Ethernet SmoothStepper plug-in and configured Mach 4 for the Taig 2000 1/2 step controller which is running a Taig CNC mill.
I apologize for the quality of the video, it was down with my cell phone and because things are running parts are a bit noisy. This video was taken at my 'day job' at the Missouri University of Science and Technology in my shop there. This Taig mill was purchased about 8-9 years ago and has been a real workhorse. The Taig controller is a bit 'old tech' in that it is a half step, unipolar, driver; consequently on low speed contour moves it can sound like it is running with a bag of marbles in the works. Rest assured it is fine. Newer drivers like my STDR-4C are much, much smoother in this regard.
The tiny Latte Panda board works great and runs Mach 4 without a hitch. One of our research groups here at the university purchased one after seeing mine (they also got the touch screen with it) they are running Matlab on it for a research project. For those who have no experience with Matlab, it is a powerful bit of software but it is really a resource hog. Being able to run it effectively on this tiny board is amazing.
