“Well, what can you write about a switch? Solidly made, it seems, plugs between my Pi and its power supply. It switches on. It also switches off - but of course you don't ever want to do that.”
“Works great but if you're using Raspberry 400 with Hifiberry-DAC it disables audio output and there's no sound in Linux desktop. I can't find any reason why but I removed switch and I have audio back on”
“Very handy. I have two computers attached to the same monitor, a Pi4 and a regular desktop. Everything (computers, monitor, printer etc) is attached to a main switch, and with this little thing I can avoid the Pi to boot on those occacions I want to use the desktop.”
