Description: This is our latest UAV Development Board (UDB4, as in, "UAV Development Board version 4"). The UDB4 comes populated with a dsPIC33FJ256 CPU, an MMA7361 three axis accelerometer, a dual axis IDG500 gyro, and a single axis ISZ500 gyro. The on-board Invensense gyros even have enough vibration tolerance to be used in RC heli applications.

By itself, the board can be used to develop a three axis IMU controller. By addition of an EM406 or D2523T GPS receiver, it can be used to develop a UAV controller for an RC car, plane, helicopter, or boat. It comes with self-testing firmware that can serve as a starting point for you to develop your own control and navigation firmware. There is even fully functional, open source autopilot firmware available.
We've removed the reset button in order to prevent in-flight resets (not good). The PCB hasn't changed, however, so if you like, you can still add a reset button.
Note: For programming, we recommend the PICkit3. Check the related products below.
