Pixhawk-lite vs PX4mini vs pixfalcon

Hi all,

Just wondering if anybody can help me decide on which small form factor pixhawk is the best in terms of cost/performance/usability.

I like this form factor, the cover, and the price, but it's missing the ability to have the buzzer, which in my opinion is quite important. Manufacturing QA/QC may be an issue.

Price is great, not really sure what (if anything) is missing compared to the pixhawk. Also, kinda needs a cover to get it to stick down. Not sure who manufactures this guy.

Pixfalcon

Great form factor, great functions, reliable manufacturer, but very very pricey.

  The only thing that the Picfalcon is missing is the dual GPS inputs and also RC outs, which you would use for something like gimbal control or landing gear through the FC. You can still use a gimble or landing gear. I'm not sure if the Xracer has these components or not. I have to agree with Tony Kenward in regards to the Xracer being a bit more of a DIY FC, Pixfalcon is more plug and play. The connections ports of the Pixfalcon sort of suck as they are not compatible with older APMs or Pixhawks. But, it's still a hands down good unit. I live in Texas a got this in a day from http://www.ebay.com/ulk/itm/201480328841

      A CAN interface, FrSky Telemetry interface and ESP8266 port are lacking on the PixFalcon. Our expectation is to make the PixRacer easy to use for all levels of users. Not just DIYers.

        The board will natively support both types on FrSky Telemetry. We wanted to do Futaba bi-directional SBus but ran out of time on this Rev. OSD is something we have always wanted to do, but it is hard to be both cheap and good. The cheap board currently work fine. I use the minimosd. The PixRacer has a dedicated OSD connector and cable.

Pixhawk lite does not fit in a ZMR 250 without removing two standoffs to clear the servo headers.

Had i only waited some more for the PX4mini ;)

Maybe add the XRacer to the comparison despite Georges experience ?

  Does the XRacer have a dampened internal imu? Also, what about barometer or barometric sensors? There's no case on this, I would think the prop wash would be a slight issue. I tried the HK pilot 2.7.2 which worked but i had issues with the barometer due to the open case. Seems like this would be the same.

    Nope, no dampening included :)
    
    Sometimes flightcontroller do come without case, the apm2 did it as well when it was brand new.
    
    Its as simple as putting a small square of antistatic foam on top of the baro and put some shrink tubing over the board.
    
    Thats the way i protect my baros from sunlight and interference since the APM1.

      I am currently flying my uncased PixRacer boards hard mounted to both a QAV250 and a Speedix AQ. I have yet to have a vibration issue. The barometer response is not much different from the PixHawk v1 or the X2 boards I have experience with. Our production revisions include more clear space around the baro chip to allow for baro chamber as part of the case.

    The XRacer is brand new. It offers nice features (CAN,ESP8266,..) and it is only 99$, fits in an ZMR btw.
    
    The Pixfalcon is available from our beloved HK, a few bucks more cheap.
    
    If i need to buy a mini px again it would be a XRacer.
    
    These days you get a pixhawk in that smaller package for half the price we were used to. what do one want's more ? MORE TOYS :)

        In my opinion its the Pixfalcon is a small PIXHAWK derivate and the XRacer is like a successor with more i/o's everywhere, newer sensors and so on.
        
        If you dont fear building a few adapter cables on your own and like to fly cutting edge HW/Software...

        Jason - The connectors on the PixRacer beta board that are pictured are the Molex CLIK-Mate connector. The production boards use a similar connector called the JST GH. The GH connector was selected by DroneCode as their new standard connector. The PixRacer as it is now called, is a lite version of the PixHawk FMUv4. If you want this next generation tech found in the PixRacer but in a more feature rich package. That board will be ready in the next 2 months.
