## Blueprint

**Open hardware.** Full KiCad schematics, PCB layout and a STEP 3D model for USB armory Mk II rev gamma are published under CERN-OHL-S v2; only the plastic enclosure lacks an editable 3D file.

_Notes:_ Verified via GitHub API against usbarmory/usbarmory (default branch master): hardware/mark-two/ holds a complete KiCad 5.1.10 project (schematics + armory.kicad_pcb) plus armory.step, under CERN-OHL-S v2 (confirmed by reading hardware/mark-two/LICENSE). README confirms this is 'USB armory Mk II rev. gamma'. Wiki (fetched) links a separate BOM per revision (beta/gamma, plus a LAN variant) and confirms chips as NXP i.MX6UL/i.MX6ULL + NXP SE050 + Microchip ATECC608B. Microchip's product/datasheet pages (microchip.com, ww1.microchip.com, digikey.com) all returned 403 to every fetch attempt (WebFetch and curl, multiple user agents), so the ATECC608B datasheet link is omitted rather than guessed. Enclosure has only a PDF technical diagram; no STEP/STL for the case was found.
