I went with the simplest option. I use mine via a pc-usb as used for imaging. So none of the options such as a display, temperature probe, hand controller etc. Simple hand wired on an expansion board with an arduino uno. Found a nice small geared stepper (had to convert from 6 to 4 wire) and stuck it all in a 3d printed box about the size of the zwo eaf.
if this is what youre after, I'll check which version I used.
