## What it is
USB armory is an open source hardware design for a compact secure computer built into a USB stick form factor, based on ARM SoCs. This repository hosts the hardware design files and developer documentation for the Mk I and Mk II board models.

## Use cases
- build a portable secure computing device on a USB stick
- run a private Linux environment on untrusted hosts
- develop embedded security tooling on open hardware
- use a compact headless ARM computer for pentesting
- experiment with open source hardware board designs
- carry an encrypted personal server in a pocket

## When to choose
- you need open hardware with published schematics and CERN OHL licensing
- you want a tiny ARM computer that powers from a USB port
- you need a trusted portable environment for security work

## When to avoid
- you need a general-purpose desktop with graphics and peripherals
- you want a ready-made consumer product rather than a developer board
- you need high compute power or GPU workloads

## Facets
- artifact type: application
- maturity: active
- function: security, embedded, developer-tools
- domain: security, hardware, embedded-systems, privacy
- platform: embedded, cross-platform
- tags: open-source-hardware, secure-computer, usb-stick, arm, hardware-design, cern-ohl, linux
