# FAQ

### Does the Butter Box give me the internet?

Not quite. The Butter Box doesn’t provide internet access. Instead, it
creates its own local Wi-Fi network that lets you access apps, content
(previously set up), and message board features offline . Everything is
stored and shared locally — no internet or data connection needed.

### How do you power a Butter Box?

The Butter Box is super flexible! You can power it using a USB power bank, a
wall adapter, or even a small solar panel. As long as it provides power to
the Raspberry Pi, you’re good to go. Go to the [Power
Supply](../build-a-box/power-supply) section to learn more.

### If I’m powering the Butter Box with a solar panel, do I need a power bank?

A power bank isn’t strictly required, but it’s highly recommended. Solar
panels can be inconsistent — clouds, shade, or changing sunlight can
interrupt power. A power bank helps smooth that out by storing energy and
keeping the Butter Box running steadily, even when sunlight dips. Check it
out this use case to know more: (insert use case URL)

### What are the security features of the Butter Box? Can I put a password on it?

Currently, the Butter Box broadcasts an open Wi-Fi network — that means no
password is required to connect. This makes it easy for people nearby to
join, especially in offline or community settings.

However, users must either enter the Butter Box’s local IP address manually,
or scan a QR code that takes them directly to the content. Since it’s all
offline, there’s no exposure to the internet or external threats.

You can configure the Raspberry Pi to require a Wi-Fi password in the admin
settings. Refer to the [Security](../security) section for more security
features.

### How much storage does a Butter Box have?

The Butter Box storage capacity is defined by the microSD card you install —
it doesn’t have fixed built-in memory. You can choose anything from a 16 GB
card up to 1 TB (the Raspberry Pi Zero 2 W supports microSD sizes up to
that). We recommend 256 GB.

| Use Case                              | Suggested micro SD Size    |
| ------------------------------------- | -------------------------- |
| Basic setup (apps + message board)    | 16 GB – 32 GB              |
| Additional content or media storage   | 64 GB – 128 GB             |
| Handling large content packs or files | 256 GB or more, up to 1 TB |

***

### Can I customize it?

Absolutely! You can add, for example, your own content - dropping in PDFs,
videos, images, and HTML pages to build a local library, or add your own
apps - including Android APKs (even if they’re not on F-Droid).

### My USB drive is plugged into the Butter Box, but the content is not displayed on the portal. Why?

Yout USB drive is probably in the wrong format. Your USB needs to be
formatted to ExFat, Fat32, MS-DOS (FAT). Refer to [Reformatting Your
USB](how-to-reformat-your-usb-drive) for help.
