is there a CPU\RAM expansion for a Raspberry Pi Zero?


Recommended Posts

I use Retroarch on my raspberry pi zero, and wish to run a certain arcade game on it. the problem is, it has a very low framerate. so I figure that I need more RAM or something. is there an external RAM thing for Raspberry Pi, and will it speed up said arcade game?

Yeah, in all seriousness, you just need to buy a more capable Pi. The Zero/Zero W are great for some things but they’re too inexpensive to be very powerful. They’re also closed designs - that is, the only way to “expand” them is to connect something via USB, the GPIO pins, etc. But those are just I/O, not a way to add memory or replace the processor. 


But because Pi Zeros are so cheap, it’s quite literally cheaper to just buy a $35 full-sized Pi 3 than even try to engineer some kind of expansion.
