## Blueprint

**Schematics published.** Mecha publishes a mainboard schematic PDF and a mechanical assembly STEP file under CERN-OHL-S in a dedicated hardware repo; no PCB layout source, Gerbers, or BOM.

### Design files

- schematic: [Comet mainboard schematics (PDF, rev a0-55)](https://github.com/mecha-org/mecha-comet-hw/blob/main/mainboard/a0-55/schematics.pdf) (PDF)
- 3d-model: [Comet mechanical assembly (STEP, rev 7)](https://github.com/mecha-org/mecha-comet-hw/blob/main/mechanicals/rev7/assembly.step) (STEP)

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| NXP i.MX95 | main SoC (6x Cortex-A55 up to 1.8 GHz) | https://mecha.so/datasheets/IMX95-datasheet.pdf |

_Notes:_ mecha-org/mecha-comet-hw repo confirmed via `gh api` (CERN-OHL-S v2 LICENSE, contains exactly these two files - no Gerbers/BOM/KiCad project). developers.mecha.so/docs/hardware/{pcb-schematics,mechanicals} pages link directly to these same GitHub files. mecha.so/datasheets/IMX95-datasheet.pdf is Mecha's own mirror of the NXP datasheet (confirmed 200); NXP's own site could not be reached from this environment to cross-check.

### Raw source files

Direct links an agent or KiCad can open (the viewer on the page reads the same files).
