Raspberry Pi 4B 8 GB
Raspberry Pi 4 B is now available in an 8GB version for you over-achievers. $75.
A 64 bit OS with direct boot from USB is also in Beta.
No this does not mean I recommend it for Octoprint. But it should work. Power hungry little beast.
I just ordered one. I'm probably not going to use it with the printer, but just to play around with.
I'm curious as to how it will perform with Retropie/Emulation Station.
Before I buy the Pi4/8GB, I would rather equip the MK3 with a 32bit board. Has anyone ever done this before?
