For under $30 you can get a new/used Android smartphone with an actually decent CPU and memory, $5 adapter allows you to attach to an existing USB keyboard for when you need one, very simple to install the UserLand Ubuntu environment.

Perhaps a pregnancy test kit would suffice. It will run Doom: https://www.gamesradar.com/12-things...ally-anything/

Default Radxa Zero

The Radxa Zero is an interesting board. The same size as a pi zero (2) w, but much more powerful and can have up to 4GB RAM and 128GB eMMC ($90 USD). I believe the CPU is a quad core ARM A53. It has USB-c etc.

Doesn't the Pi Zero 2 W not also have a quad core A53 CPU? Though the Pi only has half a gig of memory.

Yes. The Pi Zero 2 does have a quad core A53 @ 1GHz, whereas the Radxa Zero is @ 1.8Ghz. The main advantages of the Radxa Zero are the eMMC, up to 4GB of RAM and USB-C. Both are competitively priced considering their respective hardware specs. (The Pi Zero 2 and the Pi 4 8GB are out of stock!)

A53, the design that will never die. My SBC fondling is done until a cheap Risc-V device comes out that's at least as powerful as an A53 with an open source iGPU that's just about fit for accelerated display. Probably more important for general use (than an iGPU that goes beyond the essential) is an open hardware media decode engine, something that can display a desktop and efficiently decode VP9 and AV1 would be nice. 2025?

Imagine my disappointment when I found out that Pi 4B won't do H.264 or even H.265 at 4Kp60 reliably, or at all. Not with stock Pi OS or Ubuntu, my transcoder setup, and the couple evenings of expended time, at least...

Shame that usefully powerful and open-hardware embedded GPU seemed to be basically an oxymoron at this point for what little I know.

I see Odroid N2 and N2+ with 4GB RAM (but typically sans PSU and eMMC module) selling for under $100 at various sites including eBay, Amazon and here - should have well over 2x the crunching power of a quad a53 running at ~2GHz. OTOH my little avx-512-running 2c4t Intel NUC8I3CYSM1 NUC cost ~$300 with 8GB RAM, 1 TB SATA HDD and a Radeon 540 iGPU with 2GB GDDR5 cost just $300 and provides a lot more crunching power still, with footprint not much more than an N2 with case.
