Design for Production¶
Use this path after selecting a chip or module and before releasing a schematic, PCB layout, BOM, or manufacturing package. It brings together implementation references to help reduce first-pass bring-up and qualification risk: device-specific hardware design guides, checklists, module interface definitions, approved components, and EDA libraries.
Recommended Production Sequence¶
Use this as an iterative review sequence, not a one-time handoff. Check symbols and footprints before prototype fabrication; release the production CAD and manufacturing package only after design review and validation of production-intent hardware. Repeat affected checks whenever the board, firmware, or BOM changes.
| Stage | Use | Evidence to retain |
|---|---|---|
| Architecture | Product introduction and interface requirements | Chosen part, package, memory, display, audio, storage, and power assumptions. |
| Schematic and layout | Chip or module hardware design guide | Reviewed power, clock, reset, RF, storage, display, and interface implementation. |
| BOM | Approved Vendor List (AVL) and component datasheets | Qualified or deliberately validated alternates for each critical line item. |
| Design review | Hardware design checklist | Recorded resolution for every applicable checklist item and exception. |
| Bring-up | Development board references, SDK examples, and measured tests | Repeatable boot, programming, peripheral, wireless, power-consumption, and recovery results. |
| Production CAD release | Official EDA libraries plus package drawings | Verified symbol, footprint, pinout, land pattern, and manufacturing outputs. |
Use the Right Reference for the Chosen Product¶
Use these entry points to find references for each implementation task:
- Hardware Design Guides provide device-specific schematic, layout, power, interface, and bring-up guidance for chips, plus carrier-board integration guidance for modules. Use the matching checklist where available, and consult the module introduction first to confirm a module fits the product architecture.
- M2 Modules contain the μForge M2 naming rules and the draft pin-level interface definition. The interface definition is a proposal; validate it before a production commitment.
- CAD & Components contains SiFli's AVL and official EDA libraries. Neither replaces final verification against the exact part, package drawing, and selected design guide.
A Production Reference Is Not a Substitute for Validation¶
Design guides and qualified-component lists reduce risk, but they do not prove a finished product. Validate the final PCB revision, firmware image, enclosure, battery, display, storage device, RF behavior, operating environment, and manufacturing test flow. Record departures from a guide or checklist as explicit engineering decisions rather than undocumented exceptions.
