Yeah, T3.1 also has 64KB internal RAM, so both chips have enough for 160x120x2bytes.
I've been looking at this board. $24 inc LCD, jeez, would be great for directly hooking the OV7670 or other camera.
They mention using the following dev tools, which I think are all expensive. Any chance your guys' disto will work with this board?
