## Blueprint

**Open firmware.** DFRobot publishes the HUSKYLENS 2 Arduino/Python library on GitHub and a mechanical STEP 3D model, but no schematic, PCB source, or BOM.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Kendryte K230 (dual-core, 1.6 GHz, ~6 TOPS) | SoC / AI vision processor | https://www.kendryte.com/k230/en/v1.8/K230_brief_datasheet.html |

_Notes:_ Fetched wiki.dfrobot.com/sen0638/ Resources section directly (200): it lists an SVG, an 'STP Files' zip (verified 200, actual STEP 3D model, not a schematic), an Arduino/Python library zip, and the DFRobot_HuskylensV2 GitHub repo (verified via gh api, MIT license). Also checked the three wiki.dfrobot.com/sen0638/docs sub-pages given in known_links (22599/22617/22601, all HTTP 200) — they are getting-started/self-learning/power-board wiring tutorials with embedded wiring diagrams, not schematics or dimensioned pinout drawings, so not cited as files. No Gerbers/KiCad/schematic PDF/BOM found anywhere on the wiki.
