XmegaPilot - XmegaDuino based Autopilot
XmegaPilot is an open-source software and hardware autopilot for use in small radio control type aircraft and quadcopters by amateur uav enthusiasts, students and researchers.
Xmegapilot provides a natural performance upgrade platform for arduino software programmers familiar with the general Atmel 8-bit architecture.
The atXemga128A1 processor is clocked at 32Mhz and possesses an advanced peripheral architecture with DMA and Event systems. It provides more than twice the performance of standard atmega1280 arduino processors that operate at only 16 Mhz.
XmegaDuino is a cross-platform port of Arduino that supports the new atXmega processors running at 32 Mhz. It is used to program XmegaPilot.
Current XmegaPilot Development Hardware is a single Printed Circuit board featuring:
Processor: Atmel atXmega128A1
Gyros: Invensense ITG-3200
Acceleromters: STmicro LIS331DLH
Voltage Ref: National LM4040-2.5
Pressure Sensor: Bosch BMP085
Diff Pressure: Freescale MPV5004G
Data Flash: Atmel AT45DB041
Magnetometer: Honeywell HMC5843
8 R/C servo input channels.
8 to 16 servo output channels

Michael, can you tell us more about this project? It looks like it's using a lot of the same components as ArduPilot Mega--is this meant to be a derivative design? (if so, that's great--it's what open source is designed for!)
