Development boards to use with ROS
There are already some questions of this type around the ROSanswers, however they are either pretty outdated or lack information.
Since I'm going to develop an UAV I'm searching for a development board that's small and light, as some GPIO ports with PWM (since I will need to control rotors on my aerial vehicle), some USB ports (I would need at least 3, but if the board has less than that I can probably work around that with an usb hub), good enough performance to handle GPS, IMU and camera data and that runs Ubuntu (12.04?) and ROS.
From what I saw till now boards like beaglebone black and raspberry pi seem to work with ROS, however I couldn't actually find projects that use this boards in order to prove how well they behave.
Can you help me?
