## Blueprint

**Open firmware.** MCU firmware and Linux build scripts are open on GitHub, and enclosure/mount CAD is public on OnShape, but no RK3576 mainboard schematics or Gerbers exist yet; project is pre-release.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Rockchip RK3576 | Main CPU (4x Cortex-A72 + 4x Cortex-A53) |  |
| Raspberry Pi RP2350 (RP2350B) | Low-power MCU co-processor (Cortex-M33/Hazard3) | https://www.raspberrypi.com/products/rp2350/ |

_Notes:_ Checked flipperdevices/flipperone-mcu-firmware and flipperone-linux-build-scripts via GitHub API recursive tree listings: both are firmware/build-script source only, no schematic/KiCad/Gerber/STEP files. docs.flipper.net/one/mechanics/module-mounting-system links a public OnShape document for the enclosure/module-mounting parts; confirmed genuinely public via the OnShape API (GET /api/documents/<id> returned "public": true, "permission": "ANONYMOUS_ACCESS") since the interactive /documents/ URL itself redirects a bot request to /signin (normal OnShape SPA behavior for non-browser clients). blog.flipper.net/flipper-one-we-need-your-help (fetched) frames the project as actively evolving toward full openness ('no binary blobs, closed drivers, or proprietary firmware') but confirms schematics/PCB files for the mainboard are not out yet. raspberrypi.com blocks curl (403) but WebFetch confirme
