Raspberry Pi Zero 2 W

The Raspberry Pi Zero 2 W is similar to the original Pi Zero except that the CPU has been upgraded. In stead of having a single core BCM2835, it now has a quad core Arm coretex-A53 which is 64-bit. Other than that it is basically the same as the original Pi Zero.

The improved CPU makes this Pi better suited to playing games. It still only has 512MB of RAM which limits how useful it is as a desktop but the improved CPU does make a difference for gaming ( specifically retro gaming and emulation ).

The “W” in the name indicates that this model comes with wifi.

Similar to the original Pi Zero, this board is great for low profile builds. It is capable of running a full OS. It can be used more as a “full computer” rather than must a micro-controller. You could use it as a desktop system but it doesn’t have enough RAM for this to really be a good idea.

Typical use cases where this board worsk well:
