> Same GPIO
To clarify, this means exactly the same GPIO capabilities (no extras like analog inputs, etc), as opposed to full GPIO compatibility with previous generations?
Also, any idea when documentation for the new SoC will be released (i.e. the equivalent of this, for the bcm2837: https://www.raspberrypi.org/documentation/hardware/raspberry...)? Said documentation could, of course, answer the above question, but I can't find any yet.
Massive improvement if that was all that happened.
From the engineer who worked on it:
> I reimplemented the original PWM-based 11-bit audio @48kHz as 7-bit 2nd-order Sigma-Delta modulated at 781.25kHz. The effective noise floor with this scheme approximates that of CD-quality audio DACs.
from the forums https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=1364...
You can connect the RPI to a dac/amp with HDMI input or a digital audio extractor. The best quality will be found by connecting to an HDMI to SPDIF extractor and then running that into a good quality DAC.
The nice thing about this solution is that you're not dependent on the horrible and CPU-sucking USB offered by the RPI.

I've since moved the music setup to also use HDMI (the DAC in the receiver is bound to be better anyway), but sheesh, be warned.
I've no idea if it's a priority interrupt firing too much, body diode current weirdness, or some thermal issue. And I'm certainly not going to keep teasing the fault to figure it out.
MicroSD Card swapped out. Not more annoying spring ejection system that breaks.
The CPU is Cortex-A53. Cache sizes reportedly same as on the Pi 2, 32K data + 32K code + 512K level 2. RAM still 1Gbyte 900MHz.

Sounds like you'll be find if you use the original 2A power supply and NOT connect power hungry stuff.
“Lastly, there’s an upgraded switched power source that goes up to 2.5 Amps instead of just 2 Amps - allowing your Pi to power even more powerful devices over USB ports.
Note: Our 5V 2A power supply still works great with the Pi 3. For most uses, you don't need 2.5 amps of power and our 5V2A supply should be sufficient.”
Still, it would be nice if they did make/source a generic USB wall adapter that can supply 2.5 A of current. Hopefully, this new Raspberry Pi will increase the demand for such a thing.

(And, if you compare with prices in stores that have it available, is actually cheaper).
It costs $35 and comes with ethernet, wifi, and a quad-core processor.
Furthermore, it's fully supported in linux.
That's terribly awesome for what it is.
A decade ago you had to spend 50x that amount of cash to get a laptop with those specs, without linux support.
No matter how you cut it, the Raspberry Pi 3 is not bad from any angle. At all.
Truly awesome, yes indeed .. and from my perspective, completely out of left-field. Fact is, this kind of evolution rewards those who invest in the platform, and is definitely a key indicator of a successful platform strategy, wherein the benefits of standardization and compatibility, applied along Moorse curve, results in the platform becoming more and more useful. Really great that they're able to maintain the price-point, the form-factor, GPIO compatibility, and so on; all the while pushing the platform into "workstation-class" territory, bit by bit.
The only thing that would make it better .. truly, the only thing .. is if we had the ability to go up to 16gigs of RAM. RAM is lacking, but still the machine is awesome. (I'll just assume that the next $35 investment in the rPi dream that I'll make, will fix this issue..)
I've ordered rPi 3, I'm a true believer, for it to sit atop a bundle of stacks of every other rPi released so far .. and, it seems, the rPi revolution is beneficial to everyone.
I mean, this class of workstation device, for a Linux desktop system, for .. ~$50 worth of investment .. phenomenal!
I hope we see more stuff like this, and it forces the mobile power-horses to re-consider bundling the compiler onboard.
Fun Fact: with this new rev of rPi, I can develop software for the fleet-of-rPi's like never before, i.e. it'll be usable enough to just ditch the cross-compiler and other bunk needed to maintain dominance in a tech-soaked garden of various walls, smokes and mirrors .. so instead of giving my customers an App-store link this year, I think I'll just put the working system in the mail.
Bonanza!
Yeah, I keep thinking about how a tiny device with oodles of RAM would be such a killer Redis or static asset server. Or even a killer database server, for read-heavy loads.
Although am not even sure if that would be possible in the near future - for SoC's like the BCM2837, the RAM is on the same chip as the CPU+GPU, right? I don't even know if it would be feasible to build gobs of RAM into a package like that.
Of course, RPi's are still freaking awesome, and I am happy they exist.
There is apparently an architectural limit in the Videocore 4 that limits it to 1Gbyte.
The C2 goes on sale in like one or two days for $40. (edit: You can buy in now on HK's website.) Kind of a childish move for the RPi Foundation to be making so much noise about their new board right now, actually. (edit: Okay, benbenben makes a fair and accurate point. Several boards, including the first, have been released at the end of February.)
* Not entirely just like. It's an Amlogic chip instead of Broadcom or Allwinner. Amlogic is one of the few without blatant GPL abuse.
It's their fourth birthday, a pretty good time to release a new/updated product, no?
That's not all that much of a differentiator. The Banana Pi Pro only costs $12.89 more on Amazon. It doesn't have built-in wifi and it's dual- instead of quad-core, but it does have real SATA and better video. If I weren't perfectly happy with the Odroid U3 I've been using as a Linux desktop for the last couple of years, I'd probably lean toward that instead of the RP3, but that's not the point. The point is that SATA would be a nice addition, and not unreasonable at this approximate price point, even if the RP3 is already awesome.
I was wrong. Horrible support, 2 of the usb ports never worked. The community is non existent compared to rpi.

Also they have a nice battery connector, they'll keep the battery charged and switch to it if main power fails (and even keep the SATA drive powered (not sure if you plug a 3.5" one, though)).
If a board with SATA 3.0 existed, that is still just 600MB/s.
- Wifi Built-in
- Bluetooth Built-in- New System on chip (BCM2837 reported to be 1.5x speed of previous gen)
- Chip is now 64bit ARMv8 QUAD Core 64bit processor
- MicroSD Card swapped out. Not more annoying spring ejection system that breaks.
- Position of status LEDs has changed (there is a chip antenna where they used to be).
- New power switching for 2.5Amp power supply.
What is the same:
- Same USB/Ethernet controller
- Same form factor
- Same GPIO
