A basic Butter Box setup is a Raspberry Pi Zero 2 W with a microSD card running the Butter software, a USB stick, powered by a USB source like a power cord, power bank or solar panel.
In most setups like this, a Butter Box can comfortably handle **4–10 connected devices at once** without slowing down. It’s possible to have more, but performance may drop if everyone is downloading large files or videos at the same time.
The reach for it is about **5–10 meters** indoors, depending on the Raspberry Pi model and depending on walls and interference. Outdoors, in open space, it can sometimes reach farther. Think of it like the range of a home Wi-Fi router — enough to cover a classroom, a coffee shop, meeting space, or small outdoor gathering.
