Changes from Pi3 :
- BCM2837 frequencies
- LED position
- SDIO
- UART
- WIFI and BT removal

(Only) Change from Pi2 :
- BCM2837

From my point of view, it's likely more a Pi2+ than a Pi3- ;)
Perhaps we should compromise and call it a "Pi2.5".

I see what you mean. In the est they included this little gem:
This revision Pi 2 Model B board features four mounting holes for easy installation, a built-in reset circuit, and can be powered via the USB data ports.
No idea where the "built in reset circuit" idea came from (referring to the unpopulated header, perhaps). As regards the "powered from the USB data ports", not sure if there is something they know that we don't or somebody was reading from a description of the Model B and didn't realize that that hasn't worked (without some futzing around) since the B+ came out. All of this does make me suspect that their web site maintainers aren't Pi users, or at least not serious ones.

It usually takes MCM are few tries to get their web content straight. Looks like it was hurried, despite first ship being 3+ months out.

What they actually say is that the new Pi2B is a special order and it takes 97 days to get them, not that they are going to be in stock in 97 days. The specific quote is:
This product typically arrives at our warehouse in 97 days, once ordered.
What Newark (US subsidiary of Farnell) says is:
Awaiting Delivery
Contact us for more availability or to purchase on backorder
And that's quite a bit different.

One would be nuts to order this item from MCM if anyone else (like Newark) actually stocks it.

Whatever. My point is that MCM is also mentioning the product. Order at your own peril.

Farnell have it up for £29 ( vs pi3 at £32) - nice saving for those who won't use wifi/bt

Wait and see how cheap it ends up elsewhere (amazon sell pi3 for £29)

Sometimes the gears in the brain grind slowly... This change will make it possible for the revised Pi2B to use boot over USB.

Good point.
That may be handy for some people :)

With the changes in spec, I think this upgraded 2B should have been called the 3B and the current 3B with Bluetooth and WiFi should have been called a 3B+

Interesting naming ideas. I suspect the new one is simply going to be "Pi2Bv1.2" or "Pi2B2", for short. though maybe that should be "Pi2B3" to make it clear what SoC it will use (or with a nod to popular movies..."P2B2"). In any case, when I get one, I think I'm going to "overclock" it to 1GHz. Unless they're selecting the SoCs by doing bins (which is possible), it should manage to do that. Won't be for at least 6 weeks, though.

The theory is that the current 2B & B+ can boot with just bootcode.bin on the SDCard, but that didn't work when I tried it on my B+ as the USB HDD needs max_usb_current=1 or it won't spin up.

If the new 2+ or 2B+ or R2D2 (or whatever it's called) has the USB / PXE that will be a neat bonus.

The ability to boot over the USB bus, using MSD or PxE, is a feature of the SoC. Swap in a '2837 SoC and the capability will be there.

While we're on the subject of overlooked implications... This change will mean that the Pi2Bv1.2 will be able to run a 64-bit OS, should anyone want to do so. Once the CM3 and Pi3A are in the wild, that will be a capability of all Pi lines except the Pi Zero.

I think the willingness to make this change has implications for the future as well. If my contention that the next gen SoC to be used in a Pi will be a 28nm part, it will require less power for the same performance and--therefore--generate less heat. One might expect the possibility of a Pi2Bv1.3 and--potentially--a Pi3Bv1.2, both of which might be "de-rated" versions of a "Pi4B".

What about the overheating issues reported for the Rpi3? Will the new RPI2+ inherit that problem?

Probably not, as it's under-clocked to Pi 2B levels.

Look at this one as a Pi2B PCB with a 2837 on it, pretending to be a 2836. Because that is basically what it is!

Might be some minor tracking changes, not sure if the 2837 has a different BGA.

I'm not sure why you are referring to the Pi3 when this discussion is about the Pi2 v1.2 revision.

Here's the correct link:
http://www.newark.com/raspberry-pi/rpi2 ... dp/95Y1948
They are out of stock and the ETA is 11/7/16

Does its pretending extend to having MSD / ethernet boot disabled?

Jamesh may or may not know...and even if he does know, he may or may not tell us.

However, since the internal bootrom on the SoC is *in* the SoC, I don't think anyone would try to find a way to disable it. I would expect that the Pi2B2 (that's my name and I'm sticking with it) would have the ability as a "new feature". I also expect to see the feature on the Pi3A. CM3 is going to be a little tricky, but probably doable.

Pi Hut recently added some Pi 2 at 20£ : https://thepihut.com/collections/raspbe ... 8198528708

I ordered one just in time before they get sold out, hopping it was the v1.2, but unfortunately, I received it and it's "just" a v1.1 :oops:

No matter, my B+ was too slow for retropie :mrgreen:

The photos there aren't recycled 2B photos, that's an actual 2B+, early serial number, made by E14's Embest (China) factory during week 35 2016 (~4 weeks ago as of today). Shouldn't be long before they're in the wild somewhere...
