Looks so awesome! Can't wait to try it out but I gotta go get some microHDMI cables now

#542I'm so happy they haven't removed the composite video out in the headphone jack! If you didn't know, you just need a 3.5 mm TRRS connector - the pinout[0] looks like: T - Left Channel Audio R - Right Channel Audio R - Ground S - Composite Video Out [0] https://www.raspberrypi-spy.co.uk/2014/07/raspberry-pi-model...
Why? What do you use composite video for? I think the last time I used composite video for anything was 10+ years ago.
Not OP, but I love the composite output.
I have a raspberry with retroarch connected to an old CRT and an arcade stick. Old arcade games with a lot of dithering just don't look the same on an LCD.
(Some emulators now come with some decent CRT filters, but It's still not as good as a real CRT)

Playing your emulated video games on a real CRT TV so you don't have to use computationally-expensive CRT filters on your video output to get it to look even sort-of the way you remember? Can't think of another use but I assume they exist.

It is analog video. Meaning you can read the result without needing a HDMI decoder.
It also has much long range than HDMI (150 feet is cited compared with 50 feet for HDMI). You can also use boost extenders to transmit the feed over almost unlimited distances for little additional cost.
It is less useful at home, and more useful in industry, scientific, and experimental applications.

#546Can't wait to buy this, boot it up, play with it for four hours, then stick it in the same desk drawer with the other Pis I have bought over the years. (The upgrades look great, just my attention span is not so great)
That's silly. RasPis are stupidly useful.
I've got:
* A Zero W hooked up to a PM2.5 to do air quality monitoring in the house. Just bought a couple more sensors for it (VOC, eCO2, etc), but haven't hooked them up yet.
* A 3B+ running the UniFi controller for my home network.
* One is running a custom Hue automation I built to shift the color temperature of the lights throughout the day.
* One is built into an internet connected dog treat dispenser I built as a gift.
* A rather dusty Pi is running CNCjs so I can have a decent interface to my cheap grbl CNC.
* And finally I have a Pi running OctoPrint for my 3D printer.
And that's just the ones currently running. I've got two more in progress. One to automate an exhaust fan based on inside and outside temperatures. Another is destined for the garage where it will replace the not-so-great MyQ "smart" functionality of the garage door opener.
To each their own I suppose, but I've been consuming RasPis like candy. $60 all-in gets you a fairly beefy platform with almost all the I/O you could require and a vast ecosystem of software and HATs. Honestly their only downside is that at some point I'll have to reconfigure my home network when I start exhausting my current internal /24 with 200 RasPis.

Do we know for sure that all VC5/6 SoCs support HDR decoding, or is that still unknown? The Wikipedia page for VideoCore only lists one VC5 SoC and no VC6 SoCs. The Broadcom page for the VC5 SoC is pretty uninformative. Edit: I found this thing someone on the RaspPi forums put together! https://cdn.shopify.com/s/files/1/1560/1473/files/Inside_Ras... > The Pi 4 has seen an upgrade to VideoCore VI. > The H.265 / HEVC d…
The KMS in this new chip is still the old VC4 HVS (high-speed video scaler). That chip can not output any 10 bit formats. (But it also wasn't capable of 4k60, so maybe there are some modifications there.)
This was mentioned in the rpi forum by staff:
May I ask whether RPI supports things such as 10 bit video decoding, Dolby Vision and Atmos? Thx.

#548The book 'kubernetes up and running' had a description on how to set up a kubernetes cluster out of raspberry pies. I guess a setup with the new pies would look a bit more real.
I run a 4x RPi Kubernetes cluster at work. Took me about 6h to set up once I figured out newest version of K3S is borked.
We're gonna use them to deploy signage / dashboards all around the office.

Are you sure? I've worked with a myriad of ARM devices, and I would say that despite their small size, Hardkernel are one of the most responsive companies when I have had issues. I say that as both a Gentoo and Kali ARM dev
Im excited to look at the wifi on the RP4! Any word on the chipset used for that? On a more personal note - thank you for your service. You got any advice for pulling the aircrack_ng/rtl8812au driver from github and making it into a patch for building in-kernel? I really like having signed-module verification, but I also really want this driver.
The credits at the end of the post thank folks who worked on the CYW43455 integration, which matchs up with the raspberry expectation of being a (former) Broadcom part.

In the video here https://www.raspberrypi.org/magpi/raspberry-pi-4-specs-bench... they said they doubled the SD card performance.
Finally! First RPi SD card performance upgrade ever. Doubled, so I guess around 40 MB/s. Still a far cry from fastest SD cards that can both read and write over 250 MB/s. Hopefully RPi4+ will improve on this. :-)
People have spent however many years since the release of the last pi suggesting improvements. It's announced today offering basically everything that people were asking for, and you are already planning for the next one?
