Replacement: None. We don't have any of these boards left. This page is for reference only.

This batch of the old UDB3 boards tested fine but didn't quite live up to visual inspection. The solder work is a little sloppy here and there but all in all they're probably okay for the most part. Since they don't look as nice as we'd like, we're selling them as-is at a discount. If you don't mind cleaning up a sloppy board for a few bucks off then you should jump on this deal. We only have a few in stock and when they're gone, they're gone for good.

This is the previous UAV Development Board v3 (aka, UDB3). The UDB3 board comes with a dsPIC30F4011 CPU, an MMA7260 three axis accelerometer, and two dual axis IXZ500 gyros (instead of three LISY300AL gyros with v2). The IXZ500 gyros 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. With the addition of an EM406 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 also fully functional, open source autopilot firmware available.

The board also supports a connection to the faster and more accurate UBlox GPS module. The easiest way to connect to the GPS is with this adapter.

We suggest using the PICkit3 to program the board.

**Note: **On the 6 pin debug header, the pin next to the reset button is VPP, according to this convention.

**We cannot accept requests, returns, exchanges, provide documentation, or provide support on any aspect of these boards. **

Weight: 34 grams (controller and GPS)
