Those things are ancient, too. It’s annoying that there are no tiny cheap Linux SBC’s like that, which you can straightforwardly buy.
Apple’s old airport express was kinda that. You plugged it into the wall and it was a wifi repeater, had a USB port to make your wired printer wireless, and a 3.5mm jack for airplay to speakers. It was about the size of a macbook power brick, but for 2004 you can’t complain.
Someone posted this further up I remember when they came out but I don’t know much about them
Luckfox Pico Mini might be you’re looking for. It’s a Linux SBC that costs around 10 USD, in a Teensy/Raspberry Pico or even smaller formfactor.
