UPV/nMine UAV extension board for OLIMEX LPC-E2468

This board is the second design of our uav project, first one is based on OLIMEX LPC-H2294, we are moved to Olimex LPC-E2468 because this small board have very interesting hardware and peripherals for UAV applications (Ethernet, 2xCAN, 4xUARTs, USB HOST and more)

IMU details:

This board try to contain all necessary sensor, communications ports, analog inputs... for any medium responsibility UAV. It is not lightest solution but it have a lot of more hardware options and peripherals than other well known and very expensive uav controllers.

Features

4 Layer board with ground plane for high noise immunity
I/O Connectors:

8 x Servos - Standard pitch 2.54mm
4 x speed input (for sensors, motor RPM, or PPM capture)
2 x CAN BUS with transceivers  - Header 2.54mm
2 x Analog Inputs for general propose 0-5v (for sonar altimeter for example)
2 x UARTs (3.3v level) for GPS and MaxStream XBEE-Pro 60mW radiolink
