Would be nice to have. "More efficient power management" is claimed but what that amounts to isn't described. Pimoroni's graphs suggest it's about 250mA at idle which makes it worse for battery use than other Pi's.

Element14 don't sell the Zero and recommend Pi A+ for lower power consumption. That will presumably increase when the Pi 3 A supersedes it.

Nope and nope. PCB technology limits mean that we couldn't route out the FM antenna pin. It's left disconnected underneath the chip, unfortunately.
Pity - FM receiver built in would be a nice addition, complementing piFM transmitter ;)

Naughty! Some of these combo wireless chipsets provide proper FM Tx as well as Rx (the old non-BTLE capable BCM4329 is one), but not the 43428.

stupid question:

I have a pi 2 at the moment which is running openelec,
can i just switch the sd cards? will this work? or do i have to set it up from scratch?

thx

No, NEON instructions are just quicker. No compiler flags need changing.
The non-neon stuff may benefit from -mcpu=cortex-a53 instead of cortex-a7

Pi 3 support is contingent on having recent (i.e. post-release) firmware. I'd wait for a distribution release if you don't feel like fiddling with the boot files on the SD card.

Update to 6.0.2 when stil on Pi2. It will then work fine on Pi2 or Pi3.

Does the on-board WiFi have the same MAC address as the on-board ethernet (based on CPU serial) or is the prefix different or is it random?

If not can someone with a running RPi3 please post the output from ifconfig -a for me?

Does the new, official case for the 3 Model B still have the LEDs visible now that they have been moved to the other side of the micro sd slot? RS seem to be advertising it for the "3 Model B, 2 B, B+".

Thanks

I see from the pin-mapping that PCM audio is wired up to the BT part of the 43438, so that means audio out to BT headsets is possible :)

Especially for the BT/WIFI
Full Pi 3 pin-mapping can be seen in bcm2710-rpi-3-b.dts over here: https://github.com/raspberrypi/linux/co ... 3bd3fa48b7
Thanks a lot !
Unfortunately there is no information about the GPIOs for cam, lan9514 reset,clock and usb-current-limit.
What I got from the dts:

BT: uses GPIO 28-31 for PCM, 32-33 for UART0 and 43 as clock.
Wifi: uses GPIO 34-39 for SDIO

So only GPIO 40,41,42,44,45 is left. Assuming that:
Audio is on GPIO 40,45
Cam-GPIOs on 41,42
and that clock on GPIO 43 is also for the lan9514
there is only GPIO 44 left for either lan9514 reset or for the usb current-limit.
So I guess there is no longer a ethernet reset and the power-led and brownout detection have gone.

Congrats on the new release and birthday :)

Honestly a bit surprised about the BCM2837, given the fact that its only a year after the BCM2836. The Foundation seems to have quite a bit of cash lying around to afford these SoC improvements :lol:. A bit concerned about Eben saying that the B+ might outlive the 2B however. Bit of a shame to spend a pile of money on the bcm2836 only for it to get outdated a year later :? .

A question regarding the new compute module.

Will the new compute module match the pinout of the first version? In other words, will I be able to place the new compute module in the hardware I have already developed for the first version?

And what is the reason for not releasing it together with the pi3, is it development or just production capacity, or something else?

Pinout is the same, proto boards do exist and work, but still some dev work to do before release IIRC.

Releasing at the same time is just too much work!

Does the RPIv3 ETH/WLAN still pass through the USB2 bus on the ARM?
My post got deleted. Yet someone else says "The Odroid C2 is better" and theirs gets allowed. Great moderation.


So here goes, a simple question:
Does the RPIv3 ETH (and the new built in WLAN) still pass through the USB2 bus on the ARM?

Regarding the RasPi3

Why were we kept in the dark regarding the new model release?

Why did the management allow misleading information regarding the development to remain on the FAQ?

7. WHEN WILL THE NEXT MODEL OF THE RASPBERRY PI BE RELEASED?

As of February 2015, the second generation of the Raspberry Pi has been released, initially in a Model B version. Beyond this revision, which upgraded the main processor on the board to a quad core and doubled the RAM while maintaining full backwards compatibility with the original Raspberry Pi, there are no immediate plans to release any more new models. A further new model may be released in 2-3 years, but this is not a firm schedule. We concentrate our engineering effort on making the software that runs on the Raspberry Pi faster and better all the time, which is why you should always ensure that you are running the most recent firmware. -General -Top

Has the RCA audio been improved for low volume usage (hiss was ever present) ...? The only fix (that worked for me) was on Pi2 to have the volume at max on the output hardware.

Does the RPi 3 still use the same Synopsys USB IP core as previous versions? Gert van Loo said last year that they "could not touch the USB" on the RPi 2, and I'm curious if that's changed on the RPi 3.
