After suggestions from some fellow makers and users on my blog, I released the new MoteinoMEGA along with all the source and details. This is based on the more resourceful Atmega1284P but otherwise has all the other loved features of the traditional Moteino. Wireless programming via DualOptiboot+FLASH, a lot more flash for sketches (128K), 8 times more RAM! (16K), another hardware UART/serial and a bunch more IO!

I have also improved some functionality of the RFM69 library to support it and address some issues. Also I made SPI transactions nonintrusive such that it would work with other SPI devices that don't run in MODE0 that the RFM69 and FLASH devices use.
