I have a couple of Teensy 3.0 boards in the drawer here and they are pretty fast enough I think. I am a bit allergic to the USB interface when one uses high current switching devices on the machine. The USB interface is not that reliable. > >-- >atp >If you can't fix it, you don't own it. >http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
