USB armory Mk II – Pocket-Sized Secure Linux Computer
299,00 € (ex. VAT)
Overview
The USB armory Mk II is an open-source compact secure computer in a USB-stick form factor. It gives developers, security researchers, and advanced users a flexible platform for cryptographic, secure-boot, trusted-computing, and embedded-Linux applications.
This product is independently manufactured and sold by 3mdeb based on the original USB armory Mk II open-hardware design authored by Andrea Barisani, Andrej Rosano, and Daniele Bianco.
The 3mdeb manufacturing revision includes component substitutions, PCB modifications, and production-documentation updates described in the Description section below.

Description
USB armory Mk II is a high-capability, open-hardware platform built for security-conscious applications. It supports secure boot, hardware-backed cryptographic features, full Linux distributions, TrustZone-based isolation, and secure storage use cases.
It is designed to plug into a USB-C port and operate as a self-contained “computer in your pocket”. Onboard are a single-core NXP i.MX6UL-family Arm Cortex-A7 processor, 16 GB of built-in eMMC storage, a microSD card slot, and an additional USB-C receptacle.
Because the design is open source—including hardware schematics, board files, firmware, and software—you can inspect, adapt, and extend it in accordance with the applicable licences.
Key features
- Compact USB-stick-sized form factor that functions as a secure Linux host when connected to a USB port.
- Secure boot and trusted platform support for building hardened systems.
- Full embedded Linux and virtualization support for advanced workloads such as VPN appliances, cryptographic key management, and IoT gateways.
- Open-hardware design with publicly available board files, firmware, and software sources.
- Broad operating system compatibility, including mainstream Linux distributions and custom embedded builds.
Use cases
The USB armory Mk II is well suited for:
- Firmware development
- Security auditing and penetration testing
- Embedded Linux engineering
- IoT and edge gateway prototyping
- Secure key storage
- Trusted boot development
- Workload isolation and portable security applications
Why choose this over standard hardware?
Because the USB armory uses open-hardware and secure-design principles, it provides transparency and control that many “black-box” solutions cannot offer.
It is a professional-grade platform in a portable form factor, enabling security-focused development without the footprint of traditional development boards.

The official upstream USB armory repository is the canonical source for the original design and project documentation.
3mdeb is not the original designer of USB armory Mk II. This listing covers a batch independently manufactured and sold by 3mdeb, based on the upstream design and modified to address component availability and manufacturing requirements.
3mdeb is responsible for the modifications introduced in this manufacturing revision and for the products sold through this listing. This batch is not manufactured, sponsored, or endorsed by the upstream authors or maintainers.
Changes introduced by 3mdeb
To prepare the design for this production batch, 3mdeb introduced the following changes:
- Replaced the obsolete
EMMC16G-TB29-PZ90eMMC component withEMMC16G-MW28-01E10. - Updated the microSD socket selection to
Molex 503182-1852. - Changed the PCB prepreg material from
370HRto the more readily availableS1000-2M. - Increased selected PCB manufacturing tolerances.
- Updated the PCB stack-up for the selected manufacturing process.
- Increased the overall PCB width by 20 mil, approximately 0.51 mm, to address traces and components located too close to the PCB edge.
- Corrected the via arrangement on the PCB.
- Rerouted traces to meet the required clearance constraints.
- Updated component reference markings on the PCB.
- Removed test-point entries from the Bill of Materials and Pick & Place files.
These changes constitute the 3mdeb manufacturing revision and are separate from the original upstream design contribution.
Mechanical compatibility notice
Important: The PCB in the 3mdeb manufacturing revision is approximately 20 mil, or 0.51 mm, wider overall than the original board outline.
Enclosures and other mechanically constrained accessories designed for an unmodified USB armory Mk II may require adjustment. Please verify the mechanical dimensions before using an existing enclosure design.
