That would be very cool.

Some questions:
- Are the SD card and (optional) LCD display going to be supported by the software?
- Does the software support the new current limiting capabilities of the A3988 driver?
- Is the PCB going to be a 3layer one? Alegro MicroSystem recommends it as a low point ground and thermal path.
- The chip manufacturer gives a 1.2A per phase current rating, i.e. 2.4A per axis. How is the 3A max achieved?
Considering the combined heated bed + ORDuino PCB, could that be a kit with all SMT parts (including the ones for the heated bed) pre-soldered and all the non SMT parts supplied with the uncut PCB?
That would make it an unbeatable offer (at present at least)for the ORDuino + heated bed!

I know it makes it a bit bigger, but I would prefer if it gave us a ground pin for each i/o pin instead of a single ground and a bunch of i/os like on the current RAMPs shield. It makes it easy to add additional things for those of us that want to modify firmware for custom stuff.
