3689546552?profile=originalThe above picture shows PX4 Airspeed (in fact its so new this is even a picture of a (proven) prototype), a small, digital airspeed sensor. If features a Measurement Specialties (coincidentally swiss, too) 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h). Its resolution of 0.84 Pa is quite good, and delivered as 14 bit data from a 24 bit delta-sigma ADC. It also measures temperature to allow to calculate true airspeed from indicated airspeed using the MS5611 static pressure sensor on Pixhawk. As the temperature is not influenced by the heat of nearby processing components, it is much closer to the air temperature than with the previous analog sensor setup. It comes with M3 / 6-32 mounting holes. It is supported on all PX4 autopilot generation boards (and in the PX4 flight stack as well as on APM on PX4). Andrew Tridgell has intensively test flown the sensor and will share his experience soon.

This is just the fanciest peripheral, but maybe not the most popular one: The high-brightness multicolor led featured inside PX4 is also available as external option, and it is even supported by the APM 2.x boards.

3689546525?profile=originalLast but not least a peripheral only available for Pixhawk and simple yet convenient: An USB port extender, which allows to mount the micro USB port outside of the fuselage / shell. In contrast to normal USB extenders this one is for DF13 plugs and thus does not require the enormous radius of a normal USB cable in the fuselage.


All these peripherals are intended to improve the ease of use and robustness when working with a PX4 based system, and will be available shortly.

  • I could use a Solidworks based CAD model of this part, anyone know where to get one?

  • it is now available btw in the 3DR store, I guess it's availability was never announced: http://store.3drobotics.com/products/pixhawk-airspeed-sensor-kit

  • bump!

  • any updates ? can not wait more....

  • Would love to know when these will be available....

  • Any  updates? :D

  • I'll wait for the beta testers, uh, I mean early adapters.

  • It looks like the USB port extender is made out of metal. Metal and compass no likey each other. 3DR should have a design goal, no metal. Then if you HAVE to use metal, make it non-ferrous.

  • 100KM

    I was about to buy a new sensor for my APM, saw this just in time... Please tell us when are they available!

  • How short is "shortly?"
