Can't wait to try Nerves (https://nerves-project.org/) on this. Waiting for the US-based devs to wake up to find out what they think.

This is a stunning upgrade in my eyes. Going to evaluate how it would work as a dev desktop too. Just mount it behind a monitor. iHackintosh?

Can'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)

I can relate. However these days I have found a new life for those abandoned Pis: I install Pi-Hole [1] on them and set them up for family and close friends. [1] https://pi-hole.net/

What else would you recommend along side pi-hole, something easy to setup and maintain like pihole?

Depending on the purpose, for example if somebody just wants a compact home cloud, the Odroid HC2 could also - still - be considered: https://www.hardkernel.com/shop/odroid-hc2-home-cloud-two/ - Half the RAM but double the cores. I'm waiting for some benchmarks to see if the RPi4 is faster and by how much. - Also Gigabit Ethernet and it works great. My downloads are always at 108-111MB/s for the whole transfer. - Not…

The USB port on the Odroid HC2 is 2.0, but the SATA interface is connected to a USB3 but, as is the Gigabit Ethernet. Furthermore, SATA and Ethernet are connected to individual USB3 busses, as opposed to earlier RPi designs where everything shared the same USB2 bus. I haven't checked the RPi 4 specs yet, but i can imagine it's still the same layout, just a faster bus, which can be "just fine" - it should be plenty fa…

For the RPi 4, they moved the ethernet controller onto the SoC, it's not connected via USB any more.

I had a bad experience with Raspberry Pi. After few day it stops responding (I think sometines WiFi just dies) and SD card gets corrupted despite me doing my best to shut it down gracefully (made a switch for it that when pressed runs power off command) and despite swapping power supply to recommended for Pi and putting all peripherials on powered USB hub that's dedicated for Pi as well.

Maybe you have a faulty unit? While SD corruption can be a problem, I don't think it's that bad for most users. I only had that problem on my Raspberry (v1) when I accidentally cutoff power while I was apt-installing.

RPI would be awesome for NAS if you could connect SATA somehow

Only maximum 4 Gbps shared by 1G ethernet, PCIe 2 and 2x USB 3.0? Thats even less speed than 2 harddisks.

The Raspberry Pi 4 has the Ethernet controller on the SoC unlike previous versions, so it does not share the 4Gbit PCIe bus with the USB ports.

Earlier quoted context omitted.

I looked at the dmesg from someones Phoronix testsuite run and it has: [drm] Initialized v3d 1.0.0 20180419 for fec00000.v3d on minor 0 So this is vc5/6, not vc4. Additionally: Vendor: Broadcom (0x14e4) Device: V3D 4.2 (0xffffffff)

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…

> Sounds promising! (The documentation on the website should certainly be fixed if this is correct.) Now assuming Rec. 2100 is properly supported to allow connecting to HDR capable displays over HDMI 2.0, we should be good!

As hopeful as I am, that's quite a big assumption...

That might be it. I think I'll just buy another one and try again.

I wish there were some improvements in the I/O aspect of the board. Having tried to use an RPi for a small automation project, I felt limited by the single ADC input and single PWM output. I was faced with using an Arduino daughter board to do the actual IO or going with a BeagleBoard.

Driving an arduino from a pi is still the way to go, which is a shame. I’d have liked to have seen more PWM too.

Look at pca9685-based i2c pwm driver boards, it gives you 16 channels and is much more stable and easier to control from userland code than RPi gpios.
