The wait is over! We are proud to introduce the next generation 3DR autopilot, Pixhawk Mini. Pixhawk Mini is an upgraded Pixhawk designed in collaboration with HobbyKing and optimized to run the Dronecode PX4 firmware stack and QGroundControl multi-platform ground station (Windows, Mac, Linux, Android, iOS).

For just $199, Pixhawk Mini includes autopilot, GPS, and all the cables and connectors needed to get started building DIY quads, planes, rovers, and boats.

What's improved over Pixhawk 1?

  • One third the size--dimensions reduced from 50 mm x 81.5 mm x15.5 mm to 38 mm x 43 mm x 12 mm. Smaller airframes can now operate autonomously without making sacrifices for the Pixhawk footprint.

  • Rev 3 STM32 processor allow for full utilization of 2MB flash memory. Pixhawk Mini operates at only 50% compute capacity, 40 percentage points lower than the original Pixhawk. There is significantly more overhead available to run custom code.

  • Improved sensors, including both primary and secondary IMU (MPU9250 and ICM20608, respectively), lead to much better vibration handling and increased reliability.

  • GPS module included--Neo M8N with quad-constellation support and upgraded HMC5983 compass.

  • Micro JST connectors replace DF-13. We can all breath a sigh of relief.

  • Integrated piezo speaker and safety switch

What's improved over Pixfalcon?

  • Again, improved sensors, including both primary and secondary IMU (MPU9250 and ICM20608 respectively) for much better vibration handling and increased reliability.

  • Dedicated CAN port for UAVCAN applications.

  • Includes 8-channel servo output board for planes and other vehicles requiring powered PWM output.

  • Includes I2C breakout board for a total of 5 I2C connections.

Pixhawk Mini features an advanced processor and sensor technology from ST Microelectronics® and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.

Another one: Black screws that tastefully contrast with the black plastic case!

Are they mild steel? (ie: magnetic)?

it looks like holybro did the work. That's there accessories that hobbyking sells, distro, telem.

Hi Chris. 

You mentioned twice that the new IMU in the Pixfacon (MPU9250 and ICM20608) has increased reliability. Can you please elaborate more? Do you or invensense have any data to prove this claims? 

Thanks

Also you said that the Pixfalcon has been optimised to run PX4 stack Vs the Pixhawk1. Can you tell us what are this optimisations? I doubt you are referring at the Rev 3 SMT processor, as Pixhawk1 is available with the same processor too. Also with the current PX4 FW what will be the noticeable difference from Rev 2 to Rev 3 processors? 

Comment by Rob_Lefebvre on October 28, 2016 at 7:56am

He might be talking about the ICM20608 capability of 8000Hz data rates, which can help to prevent aliasing of the signal.  This can help prevent flight control problems due to vibration.  But there are a few problems.

First, the software is not capable of the 8000Hz data yet.  Neither PX4 stack, nor Ardupilot.  In fact, the much-vaunted PX4 middle-ware layer actually prevents this being possible.  Ardupilot is working on 8000Hz, but we have to work around the PX4 problems.  What is PX4 doing here?

Secondly, these aliasing problems only occur if your IMU is not isolated.  The IMU should be isolated anyway.  Because the problem is not just aliasing due to frequency, but also simply clipping.  You can't fix clipping in software.


The Pixhawk2, employs internal vibration isolation.

But the Pixhawk Mini, still requires the user to set up some kinda of external isolation.  Most users are not capable of engineering these systems properly, and you end up with a janky solution.

I've been CRYING to 3DR to make an autopilot with an internal vibration isolation system.  But they just refuse.  Well, they did it with the Pixhawk2, but then refused to bring it to market as a separate autopilot.  Chris said this was because 3DR was getting out of the discrete auto-pilot business, because it was too much trouble.  The cost of technical support for hobby users was too high.  So they were just getting out of this line of business.

But now they bring out a cheap hobby autopilot.  Without internal isolation.  I don't get it.

@ Rob

I doubt he was referring to that. 

IMU reliability can mean a lot of things... Data more reliable or sensor less prone to failure. That's why I'm asking. 

Comment by Cool Dude on October 28, 2016 at 8:46am

I guess I will try one then we will know if it is any good. I am hoping that Ardupilot is quickly ported to this platform. It might not fully meet our expectation, but it does has some improvements over others. I guess this will px5 in the software stack, since px4 is taken by pixracer. If px3 used by PixHawk2?

Comment by Olivier on October 28, 2016 at 8:49am

 Are the design files available anywhere since this is a Pixhawk derivative?

btw  the Invensense   9250 uses   the MPU 6050 for accels/gyros, which is the same chip as the MPU 6000 in Pixhawk and Pixfalcon (except it only talks i2c, vs the 6000 talking  both i2c and spi.).Not sure how the ICM20608 compares to the STMicro of the original, but would also like to know more on how "both primary and secondary IMUs  lead to much better vibration handling and increased reliability."

Oh no, another 'Expected ship date'.
