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!

Hello Pete,
I hope that you have the build done for the DZ2, it would be great to see the UDB4 in action!
Are you using one of these Axion Alpha's? I have been looking to put an APM in one of them for a while now, I think I might just copy you with a UDB4 if you are using one of them..... ;)
I've not yet had the pleasure of using the PICkit3 or any other PICkit just yet Pete, will you have one with you on the day at the DZ2, would be great if you had a few moments to spare to show me around the system :)
I also have the Maja airframe, do you know of anyone using this and the UDB4?
I will have my UDB4's, GPS units, PICkit's in store in the next day or so and cant wait to play!!
Regards
Martin.

@Anish. Yes I have one to bring (just arrived in it's box). I'm hoping to bring a UDB4 V2 prototype (the same as production except different power chips) in a new plane. I'm putting it together at the moment for testing MAVLink.
A simple Axion Alpha.
Pete, thanks for the clarity :)

NS Rana
It is possible, and Bill has outlined the technique on the UAV devboard discussions in the last few days.
My recommendation is stay with the Microchip mainstream of developers and get a Pickit 3.
Can someone tell me wether picKit2 would be ok to program it ?
On the Sparkfun page, on the right hand side, the small pictures, which enlarges on clicking, has rulers next to the UDB4 to let you see the size. You can zoom right in on the images.
Best wishes, Pete
hi,
that device looks very good.
i tried to lookup the size of the board.
can you provide us with the overall soze of the board?
thanks
robert
@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
Gotta be the best bang for bucks autopilot on the planet! Congratulations to the whole team!
