Anyone successfully using LinuxCNC on a single-board computer?
Looking to run LinuxCNC with a Mesa card (probably a 7i92) For packaging reasons, i need a single-board computer (not enough cabinet space for a full-size PC)
Looking for names/models of single-board computers that others have used successfully

i use a up squared with celeron N3350 processor:
up-shop.org/home/270-up-squared.html#/96...4gb_memory_32gb_emmc
up-shop.org/up-peripherals/248-new-up-sq...-mounting-plate.html
it works fine with the 7i76e.

i've the system running with the r13 image: www.linuxcnc.org/testing-stretch-rtpreempt/

I made a test-installation with linuxcnc on as rapsberry-PI 3 - two years ago.
3 axes with a standard TB6550-china-board via GPIO.
it works:

Does the up squared "just work" like a normal computer when installing linuxcnc? Im looking at aaeons pico itx boards as well, and It turns out other than the shape, they are effectively the same thing for the same price - but the up squared is much easier to get in small volume and short notice (I just need 5).

thanks!

jep the up squared is a little "normal computer".
the up board with Z8350 didn't work, but the up squared with n3350 (dual core celeron) works well with the debian stretch testing image.

do you have access to the hat connector and fpga within Linux? I want to run some dotstar leds (spi) as a "alarm beacon" and if I don't have to use a secondary mcu that would be nice.
