Raspberry Pi 3

[TinkerFan]

Hello there,
for those that haven't already seen it, the new raspberry pi 3 was released yesterday or so. Although the software doesn't support the built in Wifi and Bluetooth yet (Make Video on YouTube), it has it built in...
It's also running at a faster speed (as probably every "upgrade" so far).
Here's the link: https://www.raspberrypi.org/blog/raspberry-pi-3-on-sale/

  bought one. Thanks

Of course they moved the LEDs. They have to make sure each new Pi is *ever so slightly* different from the last, just to make absolutely sure we can't use the litany of existing cases. (You have no idea how frustrating it is to find the perfect case for a specific project, only to find out that it was designed for a B+ so the internal cutouts are a few mm off from the Pi 2 fitting.)

Jesus Christ. Can't they standardize on a fucking form factor already? Damn, I must be getting old or something. Time to go chase some kids off my lawn.

[MrSlack]

I agree with you. It's like every PC motherboard coming out with a new form factor. Stupid idea. Nail the form factor then engineer it into that consistently.

Also I genuinely have no use for these things. I've bought quite a few over the years with grand designs in mind and found a better cheaper solution. If I need some wumph it's lots of wumph and requires heavy ass Intel kit and the associated low levels of hassle, plus you can get a whole desktop PC for far less with things like real SATA and real serial ports. If I don't need wumph, an AVR or ARM uC will do the job. if I need some background processing, chuck it on Linode or something.

Oh and by the way, the missing software for the wireless stuff reminds me of the unbox in of the Pebble watch Dave did a while ago

[SKPang]

Just ordered one from RS.

Another CPU upgrade (woo, it's actually a modern processor now).. with the same old crap bolted on.

I have a feeling the wifi will be hard of hearing too.

One of the reasons why I bought a 3D printer. I looked at the price of the offered rPi 3 enclosure and that confirmed it was a good decision.

[wraper]

Damn this raspberry pi 3  . Today on ebay two of my buyers already requested to cancel the order of rpi 2 made less than hour ago.

nice for me, I get a super upgrade for my embedded project and not have to change things. win win!

At least they kept the GPIO port and mounting holes in the same place this time.  It was a pain when they changed to the new layout on the B+ as I had to redesign all of my expansion boards to fit the new design.  I still have trays full of PCBs for the original layout which nobody wants to buy any more.

Hardkernel  has just come out with the ODROID-C2: http://www.hardkernel.com/main/products/prdt_info.php?g_code=G145457216438

• - 2GHz quad core
• - 2 Gigabyte DRAM
• - 4K HDMI 2.0
• - about 40 to  42 US$ with heatsink included this time

No wireless, for folks that prefer hardwired.

The entire project looks like children playing with the PCB designer software. Mounting holes on the first version. Connectors on all 4 sides. SD card, not onboard memory.  The crappy wannabe windows. MicroHDMI and the paper launch of the zero. The list of issues is longer than the list of features. Its like they just do some random things, and everyone goes crazy, and they go even into printed newspaper.

I like the gigabit ethernet and adding wifi is trivial. It's 50% more expensive than a pi3 in the UK, but that only matters if you're bulk-buying and then you'd get a quantity discount I'm sure.

From http://www.digitaltrends.com/computing/c2-offers-competitive-specs-to-raspberry-pi

"... the Pi is still the most recognizable offering, and as Liliputing points out, the lack of a strong community pushing development forward may mean that the C2 does not become as popular as it might otherwise."

I actually prefer the SD vs onboard flash. Look at the Beaglebone Black. 2GB was nowhere near enough. 4GB is pushing it. Especially considering  how bloated their Debian distro is. (Raspbian is nearly as bad.)

Just give me a uSD socket and let me sort storage out myself. (That way I'm not paying for a flash chip I never use.)

All the other points I agree with.

Having 8GB microSD is especially useful for OSMC / Kodi as it allows for a large thumbnail cache, speeding up menu browsing. (My thumbnail cache is 500MB, but with the OS and all partitions and thumbnail cache I have just 1200MB free.)

[Keridos]

Ooh, gonna test this one out some time in the future, the inbuilt wifi is great for places where ethernet is not or simply ugly. But the release was a lot earlier than I expected some time ago.

It seems like there is a small issue with the UART port on the Raspberry Pi 3.  I normally use a UART to USB adapter to set up new Raspberry Pis but when I plugged it into the new Raspberry Pi 3 that turned up this morning all I got was garbage on the console.  After plugging my logic analyser into the UART port I found that the data coming out of the Raspberry Pi is about 1.6X slower than it should be.  The baud rate should be 115200 but I had to set the USB adapter to 72000 for it to work.

It seems that the new Raspberry Pi uses the original UART port for the new bluetooth adapter and the UART pins on the GPIO port is now a soft UART port which is dependent on the CPU speed and the current Raspbian Linux distro isn't doing the calculations properly to configure the baud rate.

nooooooooooooooooooooooooooooooo! argh. I'm using the  uart pins to do rs485 at 10mbps, after bumping the uart clock when linux boots.

damn. damn damn.

Wait, what? Soft UART?! Really?! Christ on a Cracker. Most SoCs have like a ton of UARTs (the Sitara on the BBB has at least 5 full UARTs with hardware flow control for example) so I assumed the BCM would have at least two. How could they think this was a good idea? Talk about amateur hour...

For twice the price?

[MrSlack]

Twice the price or twice the crap.

Or usually both of it's Broadcom (way too much bad experience with their router SoC's and NICs)

[Monkeh]

I'll just leave this here.

[tom66]

That is one toasty die. Under what conditions was that achieved?

The new RPi3 should pull 0.65A @ 5V when loaded fully, most of which will be dissipated in the CPU. That's 3.2 watts.

Send it back for a refund. You've obviously got a faulty one.
