Great work. I didn't know about the Chip Quick stuff. That was interesting in itself.
One thing you get that I noticed is a DAC on the 303, which the 103 didn't have. I'm sure there are other differences. It would be great to see these come out using the same board.

Maybe your callout for F3 Arduino support will inspire some of our members; who knows?

I've been looking at the STM32F4 Stamp that one guy came up with. He's not making any more but the information is out there to make new boards. I'm sure it will cost me a lot more to make it but looks intriguing still. It's based on the STM32F405. A big jump in power too.
