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)

Don't forget to keep it powered while it's in the drawer so you could ssh and build something really awesome.

Maybe it's a personality flaw, but I get plenty of satisfaction from just reading blog write-ups if things I could have done with my tech junk, without all the associated time invested.

It's much easier to vicariously enjoy projects like these, which is why I think drawer-dwelling is an inevitable destiny for most of these widgets.

Oh my! This is such a crazy upgrade. I've been using the RPI2 as my HTPC/NAS at my folks, and I'm so happy with it. I was itching to get the last one for myself. USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?! What the!? How the??! I know I'm not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited! I'm setting up a VPN to hook this (when I get it) to my VPS and then do…

> I've been using the RPI2 as my HTPC/NAS at my folks Could you provide some details? The USB-adapted ethernet & lack of wifi sounds limiting for a NAS.

Not OP but... If I would guess hes using OpenMediaVault? It works rather well on even gen 1 pi's.

I always feel like I'm missing something. I don't have a single idea where something like this could be useful. Maybe because I don't care about "fun" projects and live a quit minimalistic live style? I must don't have (small) problems with no solutions. Then again, I've also never had an idea for an interesting software side project.

Another way to think about this is that it's the antidote to seamless portless iGlass slabs for $1000. You've got compute, a pile of mainstream ports and wireless interfaces, GPIO pins and an established ecosystem, all for basically no money. It's an open enough platform that kids, adults, startups, schools, and companies have found endless uses for them, ranging from toy projects for learning purposes to production…

My comment wasn't meant to criticise, just open self reflection. Even reading about some of those projects, I still don't get it and wonder why. What makes some people see this tool and get all excited about the possibilities, while others like me can only shrug their shoulders? As said before, I think I'm missing something, something great I like to have but just don't.

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…

I had an Exynos 5422, and when it came out it was a great card, however, nowadays, it's old generation - it consumes more and it's less performing than the latest archictures (A7x).

"Double the cores" is not a valid consideration - 4+ core configurations typically have 2/4 cores (the 5422 has 4) with a high-powered architecture, and the remainder with a low powered one.

Compare for example the XU4 with the N2 - the N2 is more powerful, and yet, it has less cores (4 hp. + 2 lp.) and requires no fan.

The RPi is an interesting configuration - they have 4 high-powered architecture cores (4x A72) only. It seems it doesn't require any fan.

Of course if one requires specific chipset/components, we're talking about specific use cases, which is another story.

Too bad the USB-C slot is only used for supplying power instead of being a proper Thunderbolt slot with support for acting as a USB device or attaching external PCIe cards. But well, that's a thing for the 4+ then I guess...

It says the USB-C connector supports On The Go (OTG), which means it can act as both a host and a device.

I could imagine being able to power the RasPi4 and communicate with it over Ethernet using just a USB-C cable if the Raspberry Pi 4 supports USB Ethernet 'gadget' mode, which I'm guessing it will if that USB-C port is fully USB OTG compatible.

There's even a kernel driver for the CSI receiver, which we paid for ((link: https://patchwork.kernel.org/patch/9951525/ ) patchwork.kernel.org/patch/9951525/). What you can't do is clone the official v2 camera module and use the default ISP tuning, which we also paid for. https://mobile.twitter.com/EbenUpton/status/1088440503622909... Personally I…

I'd prefer if they gave us the full functionality of the device though - the imager is capable of global shutter but it is locked out.

That's a fair point. Perhaps when camera v3 is released they'll have the option of updating start.elf and removing the restrictions on using this hardware.

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.

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.

also, 15W is max power I suppose, how low can it go if you configure and use it for small tasks

from their benchmarks: https://www.raspberrypi.org/magpi/wp-content/uploads/2019/06...

I wouldn't be surprised if downclocking it would reduce the consumption even further. Also this was with a screen+kb/m attached so that's extra.
