This is a discussion to focus the feedback and support of ardupilot on the PixRacer board from

We believe that all teething problems encountered are now resolved and so we recommend people load Copter-3.3.4 which is available for all multicopters through the Mission Planner's (and other GCS's) Install Firmware screens.  Note that because regular Pixhawks are still on Copter-3.3.3 the install icon may show Copter-3.3.3 but rest assured, Copter-3.3.4 will be installed (you can check the version by looking at the very top of the Mission Planner).

Which GPS should I select when ordering this board? Thanks!

I recommend all three:

The first two are crimpers and the last one is a stripper. They are $90.26 total.

Thanks. One more thing... I see these connectors are saying a pitch of 1.25mm but I'm seeing GH 6pin <-> Separate 2.54mm females  so I'm not understanding that discrepancy can you [ or anyone ] clear it up for me? Thx


This is the specs for the JST GH connector series:

However, you need to show me where you're looking so I can see for myself. Thanks!

Looking at the PixRacer specs it's saying 2.54 mm  Perhaps one is the spacing of the pins [ 1.25 ] and one is the thickness of the housing?

2.54mm is the other end of the cable. 2.54mm is also referred to as 0.1" or 100 mil spacing. Basically a standard header connector. Think of the servo rail on the Pixhawk or the channel pins on a receiver.


"latest" (aka "master") plane supports the pixracer but the fixes are quite recent so they were not included in the last "official" release.  Plane releases go out fairly regularly and the next official one will certainly include support but I can't say when that will be.  I guess until then you could load "latest" from the Mission Planner by pressing Ctrl-Q.  That's use at-your-own-risk of course 'cuz it won't have undergone much official beta testing... but my guess is it will work fine.

Hi Tim,

Pixracer will work fine for plane. The 3.5.0 release came out before I received the final version of the Pixracer, so it doesn't have the fix for the FRAM issues. As Randy says you can fly master now, or I could push out a beta for you now if you prefer. We're close to being ready for 3.5.1 anyway.

Cheers, Tridge

Thanks Randy and Tridge. I can wait for 3.5.1. Really looking forward to  trying pixracer. Thanks again for all your work.

ahhhhh  got it. Thanks

In another forum I noticed that AUAV will eventually be offering a case.  I did see a link to designs already available from Shapeways.  The case does have an isolation chamber for the baro but there was some discussion on the location of a static port that needs to be drilled.  Has anyone done any testing on the best location for this static port?  If I ordered a case top and bottom from shapeways could I just drill a small hole in the baro chamber of the case and have this work?

I have the other controllers in cases and no problem, I'm waiting for a case to this board too.
