For full details see PX4 Release 1.6.0 (Github)

PX4 v1.6.0 requires a recent version of QGroundControl for the best user experience, currently available as “daily build” here.

New Hardware Support

  • Crazyflie v2
  • FMUv4 PRO (Prototype donation and manufacturing: Drotek)
  • FMUv5 (Prototype donation and manufacturing: Team Blacksheep)

New Features

  • New .ulg uLog logging format which directly logs uORB topics and offers more accurate time stamping. Supported in FlightPlot.
  • New web-graphing engine for .ulg: http://review.px4.io
  • Easier to use camera triggering
  • Basic support for real-time camera triggering feedback
  • Support for survey flights (multicopter and fixed wing) with intuitive UI
  • Temperature calibration and compensation (gyro, accel, mag, baro)
  • Support for MAVLink and PWM controlled gimbals
  • Support for generic helicopters and Blade 130 mixer @bartslinger
  • Fixedwing acro and rattitude flight modes

Major Upgrades

  • EKF2 Robustness
  • Tremendously better user experience on Snapdragon Flight
  • Better user experience on Aero
  • Hardening against marginal GPS reception
  • Hardening against mag observability issues
  • NuttX Update to a recent release
  • STM32F7 support
  • Change default to use the new ULog logging format supporting http://review.px4.io zoomable graphing
  • Significant reduction in RAM usage on STM32
