Just need a bigger battery. 15W is achievable. You'll add more weight obviously but you get the extras of the pi4. Tradeoff. As for the screen you pointed to, isn't an adapter available?

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

Oh this is great. WiFi and gbit ethernet onboard is what I needed. Is USB and network bandwidth still shared?

"The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports." Better than one could've hoped!!

Oh wow, this will make one of my projects go from four raspberrys to one.

Gigabit Ethernet? I'm tempted to grab a few and try running Pi-Hole for my whole organization (~1200 users) and see how that goes. :) I know you can set up Pi-Hole on Ubuntu VMs. But there's something so attractive to me about running it separate from your hypervisors and closer to the core switch on very very cheap hardware.... Been curious about Pi-Hole on my bigger work scale for a while, this may very well tip me to trying it out.

Desktop performance my behind. What's the point of all that CPU power when IO performance remains in mid 2000s territory? It takes forever to boot, any time disk access occurs everything crawls to a halt. M.2 has been around for 5+ years now and would have easily fit on this design in its short length form factor. No datasheet for the SoC either. Again. There are vastly better SBCs out there.

> There are vastly better SBCs out there. Can you provide some examples please? Always keen to try out any alternatives

I'd love to see other interesting $35 SBCs with reasonable performance.

Has anyone had success using an ARM based system for local development in Linux?

Yes. I use mine for a lot of back-end development (I can run Ubuntu on them and Docker, and have a bunch of containers built for them as well, via a multi-arch pipeline[1] I have been adding to for a while and just cleaned up for re-use).

This looks usable for desktop tasks, does anyone have tips for a good display to pair with it, optimized for energy saving (in the 24", FullHD class)?

I’m not very familiar with the hardware here but could someone elaborate on why this seems to be such a big deal that there are four versions of the announcement trending on the first page?

You can buy a pretty powerful full computer (networking, video, RAM, etc) that fits on a tiny card for $35. That makes it possible to build all sorts of fun things on next to zero budget - everything from robots to video game emulation systems and tv streaming boxes. The previous 3 versions were already wildly popular, but there were starting to show their age and to be significantly outperformed by Nvidia's Jetson N…

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.

They remove all the bottleneck from the previous generations making it more interesting for networking and desktop use.

All? What about that nasty SD card?

You don't have to boot from the sd card, so I think that's a legitimate statement.

I've got an sd card reader on my laptop, it isn't a bottleneck though.
