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.
Comments
could be a good quality if you can disconnect your connector if you want , but i had a lot of problem on that kind of component . That was in my first report to Lorentz on PX4 , now we have that component for gps and power module but i don't like it a lot ... i think that for future release of VRBrain i choose other better solution .
Will a "configure" menu be added? (i.e. $10 off when bundled with the gps)
Don't you think that's a good quality to have when it comes to components of a flying lawnmower?
I agree the other problem is that sometime have a lot of problem to disconnect it.
This looks great, but there's some problem with finding those micro jst plugs/cables, and there's a lot of them on the Pixhawk. Do you know where to get them? The telemetry plug for my APM 2.5 had to be taken from inside of Asus laptop :) I know 3D Robotics would supply them, but they are really fragile, and could be broken easily.
Is this exact flight controller on Iris !?
Great to see S-bus in there.
So I can start saving to buy a few, any idea on price yet?
Comparable to current APM's ?
Wow this is awesome, didnt make the jump from APM 2.5 to the PX4 or VRbrain, gotta love the new toys!, Well done!
The design is very nice .. but i'm not agree on the sensor ... and connector i'd like other option.
ST Micro L3GD20H 16 bit gyroscope.
ST Micro LSM303D 14 bit accelerometer / magnetometer.
I try it on VRBrain 4.0 but I prefer the MPU6000 + HMC5883 .
I think that on sensor need to invest more money for a good result ....
Why you don't support PPM but only PPMSUM that could be a limit.
The STM32F427 is nice , but is only a 407 with more RAM and FLASH or there are also more advantages ?, i see on datasheet that is pin to pin compatible with 407 so i can upgrade my 407 on VRBrain 4.5 if we need more flash and ram resource that's good.
best
Roberto
Any ideas of the price yet ?
