I've been following DIY Drones for awhile and in the past have purchased several components that made up the pre-oilpan era of electronics.  I was looking forward to the proposed ArudPilot-lite board that appears to have since been canceled.  So I made my own!  And in the process, learned great deal about designing, fabricated and programming Arduino.

At this point it has not seen any flight time.  But all of the electronics are on a single board and have been tested.  What you are seeing is Rev3 which has a GPS, 3-axis accelerometer, 3-axis gyro, 3-axis magentometer and a pressure/temperature sensor on board.  5 servo inputs and 4 outputs.  Servos can be powered by the battery or from the ESC.  Battery voltage level is monitored using a voltage divider, and there are 7 IO pins available for expansion.

If you'd like to follow my progress, I'll be updating this page as I go along:  http://www.happicow.com/arduvolans.php
