You can use a portion of the flash memory in the Due as a substitute for EEPROM. It has lower write endurance than true EEPROM, but this is unlikely to be a problem. If necessary you can use wear levelling to mitigate it. Alternatively, use a file on the SD card to save the parameters, as the leading 32-bit firmwares do.

I like the screw terminals near the blue fuse
any chance the remaining 8 can be same type?

I see a potential problem there:

If someone uses a too long wire for the terminal, it could make contact with the bare back of the MOSFET.

about the fork style terminals
i had the same problem with one of the 30A LED psu's
what i did was folding the 2 forks to it became a pin instead, cant quite remember how i did it it but it was easy enough
i basicly ended up with both forks on top of each other

Hi guys,
If it's not too late to make a suggestion, I recommend these connectors:
[www.digikey.com]
They are screwless terminals, similar to what we use which are mounted to DIN rail in industrial control panels. The beauty of these connectors is that they simply do not come loose, and there isn't any screw to strip out.
