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!

Sweet - I have been looking for a reason to jump in the UDB pool, I guess this is my excuse!

Clicks to the group Peter Hollands did a great job of cheerleading the other day for UDB, not sure about the skirt and pom poms though.

Really nice price for so much processor power !  :)

Ben, is the two way telemetry working in UDB4 ?

I have just ordered mine from SF.

Just to let everyone who lives in the UK/Europe that we will be stocking the UAV Dev Board v4 at our store.  We will also be selling this as a Kit that will contain the board, GPS module, headers and servo cables.

I know basic code exists already, but any plans to develo tge quadcoter side of Matrixilot? Lots of potential!!
Comment by Rana on October 21, 2011 at 12:58am

What about magnetometer , pressure sensor and sonar ?

Can UD4 use APM IMU shield sor such above mentioned sensors and still use its own gyros and accels ?

Comment by Alex on October 21, 2011 at 1:25am

I am sure that the UDB4 will be able to use an add-on Magnetometer, and pressure sensor and sonar in future


The current UDB3 supports the DIYD magnetometer. So I guess we will just have to wait and see, but for the price sparkfun are selling it at, I think we are going to see alot more of the UAV dev board in the future!  

I know I am going to get one

Gotta be the best bang for bucks autopilot on the planet! Congratulations to the whole team!

@Rana, Rudimentary MAVLink bi-directional communications are working in the UDB4. What do I mean by that ?

In the current main trunk, you can change just two PID values: Yawkp and RollKp: It was a proof of concept. Adding more variables is just a question of spending some time on it. (not very complex actually).  All MAVlink message can be parsed, but we don't take actions yet on the MAVLink incoming messages to the plane. (Other than increasing frequency rates of raw sensor information). All my MAVLink testing has been done in X-Plane HILSIM; but I've just bought a small Axion Alpha for flight testing MAVLink.

All the other Bi-drectional functionality that was in the UDB3 is in the UDB4. e.g. Camera Targetting of another plane that is broadcasting it's position.  Best wishes, Pete
