i see the new Raspberry pi computer came out yesterday.
pi 400.
it is safe and simple to overclock it to 2.2ghz per core.....4 cores 64 bit...... because it has a very large heat sink. (using 2 terminal commands)
i mean a "pi zero" computer is just 5 bucks and a 20 cents micro usb to usb adapter.....plugged into your laptop usb socket,,,,,and it's up and running.
(you need a micro sd card)
youtube vids show it.
but the new pi 400 is the same power as the pi 4.....but inside a computer housed keyboard
at $70.....it's pricey but ....well
It supports dual 4k monitors out of the box etc
thx
