SparkFun released a new version of the UAV Dev Board today. It comes with a new, faster processor with much more program memory and RAM, and loads of extra digital and analog IO.
MatrixPilot 3.2 is already fully compatible with the new board, including support for the expanded set of RC Inputs, Servo Outputs, analog inputs, PPM Input, and even the native OSD.
The gyros have even less drift than on the UDB3, and thanks to Bill's continued research and development, the dead reckoning IMU is rock-solid.
Another nice feature is that SparkFun dropped the price down to $100!
