New Raspberry Pi 3 is about to be announced, it will bring 64-bit 1.2Ghz cores and Wi-Fi connectivity. It is surely an exciting update for Navio2 and we can’t wait to get it into the air.
It is expected that the new processor will be similar to the previous BCM2835 with upgraded cores (probably Cortex A53), just like it was with the previous upgrade from single-core ARMv6 to quad-core ARMv7. That means that the peripheral blocks should stay the same and will have a high level of compatibility while bringing more performance. Cortex A53 is 30-40% faster than Cortex A7 according to data from ARM.
Build-in WiFi and BLE should simplify the configuration of the board eliminating the need in USB adapters.
As soon as we get our hands on the board we will make sure that it is supported by APM and will work with Navio2 autopilot HATs. As Raspberry Pi foundation maintains 40-pin connector compatibility it should be a seamless upgrade. We are yet to see how different the software will be for the new processor.
Thanks to CNX-Software for bringing the news. You can read more about Navio2 autopilot at emlid.com .

Odroid CO and C1+ have SPI. I haven't seen the exact Odroid specs for C2 yet.
I don't really see any reason why 3 people from Erle should directly confront Mikhail in this manner, without any provocation.
As an independent developer who's worked with almost all generations of Linux AP shields from Erle and Emlid, (Navio1, Navio+, Navio2, ErleBrain 1, ErleBrain 2) I have to say the the Navio 2, from a purely engineering perspective makes more sense. The GPS module onboard is a boon, *especially on a RPi* since the Pi has only got a single UART, and no other digital, onboard-suitable buses like CAN. The Ublox on the Navio2 has been interfaced via SPI, which leaves the serial port free, and importantly, more so (now) for upgrading the STM32 IO chip.
When it comes to the PXFmini, the board is great but has a different target config (mini quads, racers) and I don't see why anyone would like to limit themselves to it on a full-sized Pi board. The PCA output driver makes sense on this board since it's simpler to implement, and cheaper as well. You also don't need to change output rates on the different channels, which is just fine for a multirotor, but not for e.g an airplane.
Both boards are very nice, but are aimed towards to very different target audiences. Makes sense to choose a platform first.
And saying that Emlid is hijacking posts is BS. I mean, you're allowed to ask if you suspect someone is ripping off your work, no?
As far as the Odroid Cx series goes, no one's going to have any luck there, because the recent ones have no SPI, and the original ones had a rubbish i2c implementation with timing issues.
I don't care anything about open hardware anymore, but still considering publish the schematics when pix2 went production.
Dji has Left us behind too far we better come up with something. Px4 stack is now primary hardware target but with limited doc and popularity. People only laugh at 'those amp guys' if nothing come out blue very soon.
Integrated GPS but external GPS antenna needs to be mentioned here though too. That's not quite the same.
Smaller platforms also have space restrictions where GPS placement is difficult for RF separation, making some of the argument for separate GPS mute, like on a 250 or smaller quad. There are platform dependent constraints which make generalizing "which is better" irrelevant. I'd define the platform first and then argue it's merits.
In regards to Raspi3: I'd still prefer a Odroid. The Odroid CO fits the Navio 2 (faster than Pi2) nicely and the 64Bit C2 is coming next month which is faster than the Pi3...So who cares about Pi? ;-)
I know nothing about this apparent tension, but looking historically at APM, integrated GPS has always been a source of trouble.
Personally I am more interested in the functionality of the chip used on the RPi3, since shields can be added later as needed. For one, internal wifi is great from a integration stand point. But without external antennas it would be worthless. Also can you disable it, when you need to use other equipment on 2.4ghz etc.?
Improved video hardware would also be nice, for low latency live streaming.
First at all, this is an open forum and everyone can post links and their opinions. Mikhail, you are doing the same thing, posting your product here as a marketing campaign. Also you are hijacking other posts with your product: for example [1].
PXMini is smaller and cheaper but not include the GPS. And I think that not including the GPS is a great point because of the electromagnetic compatibility. I have a Navio+ I'm not able to fly in autonomous modes because of the compass it's completely crazy.
I think is great that the people can choose between different solutions. For this reason exists this forum. Please don't try to monopolize the posts because you find first the news of the new Raspberry Pi 3.

Iñigo, perfect, then let's just stop it.
I dont think that integrating GPS in the sensor cape is good idea from compatibility side...
And @Mikhail you're being unfair respect the statements you've made about Victor. And also about Erle contribution to this open-source based community in general.
To finish, I also don't think this kind of crooked discussion makes any sense in this page.
Alex, the tracking code will be sent to you next week, watch the email box:)
