Arduino Mega(or for those of us who don't speak Portuguese)Looks like this board will soon be released, which could be very nice for anyone that isn't planning on using the ArduPilot boards, and it might even be compatible with the ArduPilot code already out (I'm not too sure about that, though).Either way, more I2C, PWM, and UART channels are never a bad thing!
@Noth666: If you know the time it takes to switch tasks and handle interrupts then, a scheduling analysis should answer your question. The FAA, among other people, have some interesting docs on this topic:
I've been looking a bit at the ATMega2560 which has basicall all of this too, 4 uarts, 16 PWM, 16 A/D IO, will prolly start prototyping on this.
But my main concern would be how will the 16Mhz core cope with tons of more added features? Anyone have any idea about this?
I was thinking of skipping the RC controller for anything other than disaster backup, and running all main control over XBee on separate serial port, GPS on separate port etc.
It can to control 6 servos by hardware, and... 4 serials!!! That means GPS, Modem, PPM decoder, and data logger. About 150 waypoints of capacity. Ant post says:
The next 26 of march will hit the market a bomb! The most recent Arduino platform, that will definitely set arduino as an alternative micro in the robotics market and beyond! With great processing, memory and pins capability's, is exactly what we need!

I made the board a bit larger, brighter for a better look -http://www.tc.faa.gov/its/worldpac/techrpt/ar05-27.pdf
Hope this helps
