Almost exactly one year after the first PX4 announcement, we would like to introduce our newest member of the family, Pixhawk! For those familiar with the existing PX4 electronics, it is the all-in-one board combining PX4FMU + PX4IO, combined with a processor and sensor update and a number of new features. The current board revisions will however remain in full service and active development and are fully compatible. Pixhawk is designed for improved ease of use and reliability while offering unprecedented safety features compared to existing solutions.
Pixhawk is designed by the PX4 open hardware project and manufactured by 3D Robotics. It features the latest processor and sensor technology from ST Microelectronics which delivers incredible performance and reliability at low price points.
The flexible PX4 middleware running on the NuttX Real-Time Operating System brings multithreading and the convenience of a Unix / Linux like programming environment to the open source autopilot domain, while the custom PX4 driver layer ensures tight timing. These facilities and additional headroom on RAM and flash will allow Pixhawk the addition of completely new functionalities like programmatic scripting of autopilot operations.
The PX4 project offers its own complete flight control stack, and projects such as APM:Copter and APM:Plane have ported their software to run as flight control applications. This allows existing APM users to seamlessly transition to the new Pixhawk hardware and lowers the barriers to entry for new users to participate in the exciting world of autonomous vehicles.
The flagship Pixhawk module will be accompanied by new peripheral options, including a digital airspeed sensor, support for an external multi-color LED indicator and an external magnetometer. All peripherals are automatically detected and configured.

Availability
This announcement is a service to our users and developers to allow them to plan their hardware roadmaps in time, and to show what we're currently working on. The board will not be immediately available, but 3D Robotics is taking pre-orders for Pixhawk now, and will begin shipping in late October [Update 11/11: the current expected ship date is late Nov]. The price is $199.99.

Here in Denmark they don't grab the cash until item is shipped.
This is what I believe is being discussed: http://www.rangevideo.com/index.php/3dr-pixhawk-ppm-encoder.html
If I order from them now I would get it sooner that my pre-order unit without the opportunity cost since #DR took the money way upfront.
@Butch. No need to apologize :)
@Charles. That might also might be true. But AFAIK, it's been made a choice to send out to the distributors first, after that to the customers, even those who pre-ordered.
I can live with the waiting, but it really does take the meaning of pre-ordering. They should have warned us that "If you pre-order, you'll be waiting longer".
@Robert I owe you my sincerest apology. I did misunderstand. Also, I was unaware that anyone other than beta testers were getting the Pixhawk before us who preordered. That is what was indicated to me and that approximately 90 per day were being shipped out to the early preorder folks when the problem was discovered. Quality Control (QC), while checking the finished products before they were shipped out, apparently found the issue and stopped the shipping line. Again, my apologies.
well I believe that even the resellers in some cases pre ordered too and even some took pre orders themselves
sometimes retail can be very hectic
@Butch. I Think you misunderstood me. I never wrote nor implied that they should hurry out the Pixhawk, and send them to us Before proper QC.
Apparently 3D Robotics was satisfied with QC and started shipping out the Pixhawks to Resellers (and thus letting people who have not pre-ordered the Pixhawk buying them Before us who have). That is why I feel disappointed, I'm disappointed that we who have pre-ordered is last in line, not first.
I'm not negative of the Pixhawk or anything, just the choice of logistics priorities.
@Robert Wiklund There was a small problem discovered last week while the team was sending them out. My understanding is the issue involved a flash memory card. I for one am glad to know the problem was identified and the unit I receive will be problem free instead of having a potentially defective dataflash card. Mine was also preordered and has been delayed several times. I'm just glad they are taking the time to make sure what I receive is thoroughly QC'ed and is the best they can deliver.
I work in the Airline industry and have to deal with QC and QA issues daily. QC is very important due to the hazardous nature of flying machines. A gent at our club recently had to have many stitches on his fingers and arms due to a quad getting away from him in his apartment. It was an ugly sight and I am glad 3DR takes a little extra time for safety.
Sorry for the rambling post but I just think they are doing a fine job. Maybe others see it different.
I pre-ordered the Pixhawk several months ago and it still haven't been shipped. I feel a bit disappointed that many of us who did pre-order the Pixhawk get it Much Later than those who did not. The Pixhawk is delivered first to resellers so anyone else who did not pre-order it can buy it. We who pre-ordered showed commitment and helped 3DRobotics by letting them know the demand. Our thank's is getting the Pixhawk later than everyone else :(
Lol, you obviously didn't wait for the 2.5 release. That one seemed to take foreeeeeever.
I'm really not convinced presales are a good thing.
