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.
Great form factor, great functions, reliable manufacturer, but very very pricey.
vrbrain core seem impressive
what is the price for you new board?
The VR uBrain is a nice board indeed. Did two builds with the previous version (5.0) , sandwiched in an SD card package where I could attach the baro foam in betweenn and the anti vib foam underneath .
But I did not know the VR Brain Core yet, very interesting form factor ! Is it required to compile Arducopter for it, or does it run with the uBrain FW via MP as well ?
Another alternative: After my 2nd PIXHAWK LITE came DOA (LSM303) , I ordered a PX4LITE .In fact a PIXHAWK V2 derivate despite the name. I implanted it into a Cheerson CX-20 / Quanum NOVA and did a few pics.
Nice housing, clear connections.
Obviously some components left away, build quality better than PIXHAWK LITE, some sort of internal damping, which did not work too well, counter weight to small ?
but with HK orange latex,I´ve got incredible low vibs
I made a connection diagram
and yes I installed a Mauch Hall sensor Power Module as well. (100A version)
And it flies great, with stock PID, I just had to set up Emergency Motor Stop @ Ch8 because the land detection of 3.3.2 doesn´t work too well with this light bird (it does at my heavier builds though)
So the PX4LITE is sure a great alternative for those cheap builds.

Just received my gold px4lite. Did you have trouble calibrating the internal mag? The live calibration does 3 samples then hangs. If I disable the internal compass and use only the external, the calibration runs fine (the sphere rotates, get lots of samples, finishes successfully). I figured maybe the lsm303d was dead, but looking in the HUD-status, I see values for both imus and everything looks normal.
Compared to the pixhawk lite, the px4lite did drop the 4th serial port but gained the buzzer and led? What about the the included pdb/powermodule?
Look interesting enough to order one.
Tom, they dropped dropped the AUX,CAN, SPi connectors as well. Concerning the 5/12V pdb /Powermodule with rubber dampers, one could buy as well (not nec. included)...For my taste: Waste of space and my logs were great using HK Orange Latex. Since the Nova is a 3s bird anyways, I don´t need a big surface HK style 5V/12V supply.
Gervais - I do not think the PX4LITE is a PixHawk2 derivative. That would require mechanical vibration isolation. This board is a PixHawk1 derivative.
In fact, PX4v2 was meant. I wrote that, because the name PX4 is pointing to a PX4v1.(like Airbot FC) .
Although the PX4LITE is coming with an mechanically vibration isolated IMU (embedded in foam), its sure no PIXHAWK 2 (which is not called PIXHAWK V2..) derivate ;-)
Sorry for the confusion.
Please take care there are 3 different versions of the PIXhawk light 1. bad silk screen 2.reversed POWER connector 3 . reversed I2c & UART ports to built in compass . the PIX HAWK falcon seems to be consistent. stable design the one I like the most though is the Pix hawk light you can find the new gold Pix Hawk . RC groups as well as Diy drones threads on them!
the falcon with NM8GPS
A bit cheaper and it shipped out immediately.
