Finish that migration yet?
Yep. My current challenge is finding a bootloader that works with SD cards and fits in 2048 bytes.
If folks are wanting to move now and can program an AVR atmega328, let me know, and I'll kit up the parts. Otherwise, I need to find a way to do field upgrades, or the shipping of boards back and forth will becoming tiring very quickly. I am sure folks will find bugs, so user upgrades are very important.
I have a 3092 byte SD card bootloader, but have not gotten it down to 2048 bytes yet.
