> 1GB LPDDR2 SDRAM When are they going to upgrade the memory? All of that is nice, but what I've really wanted is one with at least 3-4GB.
When Broadcom has a less shitty SoC for them…

#182Re: New Raspberry Pi Model B+
#183I am always impressed at how people can buy a fully functional computer for $35. That said, as an engineer I often cringe at the compromises made. Like "Gigabit Ethernet over USB 2.0". Since the top bit rate of USB2.0 is 480Mbps and GbE is 1250Mbps, USB 2 only has about 1/3 the bit rate to support it. Now it will be faster than 10/100 ethernet connections but don't expect to send a 100 megabytes/second through it.
So, to be fair, they both refer to it as 'faster ethernet' to try to distinguish it from 'full Gigabit' and say explicitly in the post:
> While the USB 2.0 connection to the application processor limits the available bandwidth, we still see roughly a threefold increase in throughput compared to Raspberry Pi 3B.
And then show that they're typically seeing 314Mbps for TX/RX in iperf.

For any problem, there is always someone who could come up with a brilliant solution and makes me feel like a dummy. That is a great idea I haven't thought of! PS: Upon further inspection, PXE netbooting is already possible on the 3B under the name of "USB booting," it's just not the default in the hardware, and there might be bugs that are fixed in the new version.
But remember you can always put the very latest bugfixed version of bootcode.bin standalone on an SD card and use that instead of the version in your Pi's bootrom. This also works for older models (Pi/Pi2) that don't have PXE support in their bootrom.
Even with the new bootcode.bin, Pi 3 firmware netbooting has been extremely unreliable for me.
And at this point, if you already use an SD card for the bootcode, might as well put the whole U-Boot onto the card (which I did)

#1852GB of RAM would've been more important to me than all the listed changes.
For network applications the improved networking speeds are far more important.

That is interesting, I didn't even know that was a feature that was capped on the RPi. I can see that being made into very compact 3D Scanners very quickly after launch if that was added as a feature.
To clarify, the "3D video feature" is nothing more than being able to record simultaneously from two cameras and merge the video inputs into side-by-side H264 stream. Combined with hardware H264 encoding with delay of ~100 ms, this is very useful for certain applications (in my case, live 3D video broadcasting from UAV). I'm not aware of any other "tinkerer-friendly" board capable of that.
I'm thinking something like this could be used for a depth sensing application; a visual rangefinder.

wait, since when can gigabit ethernet transmit more than a gigabit per second?
Re: New Raspberry Pi Model B+
#188"Just over two years ago, we released Raspberry Pi 3 Model B. This was our first 64-bit product" Very unfortunate that their in-house developed and promoted OS ("Raspbian") only supports armv7, thus leaving the vast majority that doesn't know about the existence of (or how to use) archlinux ARM an the likes with a 32 bit os. Am I the only one that doesn't get the sense out of this here? Debian supports Aarch64 out of…
To me, that makes a lot of sense. Having only one architecture to support and one image to rule them all across the product line is quite a great thing to have. The other day, there was a person who had a "reddit gold" bounty for the first person who can help them get the Pi 0 online. The person basically couldn't get the Pi Zero on the wireless network. They had no USB-OTG adapter or mini HDMI adapter they could use…
I'd love to give reddit gold (if I had any) to anyone who could point me to a source for the Pi Zero at the price point it was originally supposed to be selling at: $5.00
I have yet to find it - you can get them cheap, but no where near what the RPi Foundation advertised them at when they first were announced/launched.

It depends where you are. Microcenters generally have them for $5 ($10 for the 'W'), although for Pi Day they're both on sale for $3.14. Sadly, there aren't any near me, but I had a relative who is near them pick up a literal handful last time they came down.
Several online places have them for $5, but shipping 'kills the deal' as they say.
