New 3DR autopilot: Pixhawk Mini


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.

    I've just pushed support for the PHMINI to ArduPilot master. I ended up doing it with the new thread-per-bus in-tree driver infrastructure rather than using the PX4Firmware drivers. That has a major advantage of giving 4kHz sampling on the ICM-20608 accelerometer and 8kHz sampling on the gyros and it greatly reduces the number of timing overruns as compared to the PX4 driver layer. I've only done bench testing on it so far. I'd appreciate reports (and DF logs) from anyone who tries it.

  • @Tridge. Good news. Wish CA had timed his announcement of this after he had sent you one and could have said with clarity it ran Ardupilot. Would have saved him some grief!

    Just so we are perfectly clear, from the terms of service:
    2) No discussion of politics or religion. This is not the place to discuss your views on the wisdom of military use of UAVs, any nation's foreign policy, your feelings about war, or anything else that is inclined to turn into a political debate. It is our experience that the rules for good dinner party conversation--no discussion of politics and religion--apply to online communities, too. DIY Drones aims to bring people together, and we find that discussions of politics and religion tend to polarize and drive people apart. There are plenty of other places to discuss those topics online, just not here.

    Regardless of your personal feelings (and mine), climate change is overtly political- especially with your direct mention of "presidential race" in this context. It is likely to lead to problems and violates the TOS, hence it should not be included in this thread.
  • @ RM,

    I agree with you that political discussions have no place here.

    But as an example of business practices and how they are carried out here, often in direct conflict with well proven scientific facts (of which climate change is an example), it was relevant to this conversation as it has evolved.

    While it may have political overtones here, the disparity between myth and science can be and in this case is relevant to this particular thread.

    @ Trdge / Chris very happy to hear that you have a Mini and definitely look forward to it's operating with ArduPilot and Arducopter.

    It will certainly be good to have another "Pixhawk" available which can be depended on to work.

    Chris has sent me a Pixhawk Mini (thanks!). I will try to get this tested and in ArduPilot master in the next day or two.

    It's probably best to avoid all discussions on climate change here, as with religion its a fast descent to the bottom on non related forums (plus it has nothing to do with the op, it's author or the current discussion).
    Please see the TOS on the bottom right of screen if clarification is required. Thanks.
  • Hi DG,

    I notice you live in the US, I can't understand how you could not know.

    Exxon Mobil and the Koch Brothers are both staunch supporters that climate change is a myth primarily intended to keep them from producing more oil and is without any legitimacy.

    Of course this is utter nonsense, but basically all the corporations that would be negatively affected by being forced to reduce pollution or production entirely support it.

    The quick buck apparently completely trumps the survival of the human race or any reason or common sense for that matter.

    Just look at our presidential race and you should know that scientific truth counts for absolutely nothing here.

    Sadly I am afraid we are truly doomed no matter how it comes out.

  • @ Gary McCray.  Is still called climate change? I don't anyone that denies climate changes. 

  • @Gabriel. Indeed. A new day, a new pivot, or so it seems.....

  • Meh....Ill wait for Pixhawk 2 to mature
