S3Suite
Engineering Suite
Centralize every schematic, firmware build, BOM, test report, and certification in one version-controlled system. No more shared drives. No more FINAL_v3_REAL.
Documentation
Every document versioned.
Every revision tracked.
Engineering documents belong in a system, not a folder named "Documents_FINAL." S3Suite gives every document a version history, links it to the product it belongs to, and controls who can access it.
Version-controlled document templates
Automatic revision history
Role-based access and file passkey protection
Document tagging and categorization
Manufacturing Vault for production handoff
Golden sample registry
Hardware Files
Schematics, PCBs, Gerbers.
All versioned. All linked.
Stop asking "which version of the schematic did we send to the vendor?" Every hardware design file is versioned, linked to its product, and packaged for manufacturing handoff.
Schematics
Version every schematic revision. Link schematics to the product and variant they belong to. Full diff history.
PCB Layouts
Track PCB design files with layer stackups, design rules, and version history tied to each product revision.
Gerber Files
Store and version Gerber outputs alongside the source design. Package them into the Manufacturing Vault for vendor handoff.
Assembly Drawings
Maintain assembly instructions, 3D models, and mechanical drawings. Link them to BOMs and production variants.
Firmware Management
Every build tracked.
Every version linked.
No more firmware binaries on a shared drive named "v2_final_USE_THIS.bin." S3Suite tracks every firmware build with full metadata, links it to the product and variant, and integrates with your git repository.
Full version history for every build
Build metadata (commit hash, toolchain, build date)
Git repository integration
Link firmware builds to products and variants
Track which version shipped on which device
OTA update path via S3 Protocol
Bill of Materials
BOMs with
built-in intelligence.
Your BOM is not a spreadsheet. It is a living document that needs health scoring, alternative tracking, and lifecycle alerts. S3Suite treats it that way.
Health Scoring
Each BOM gets a health score based on component lifecycle status, supplier risk, and lead times.
Alternative Components
Track alternative parts alongside primaries. Swap without scrambling when a part goes end-of-life.
Lifecycle Tracking
Get alerts when components hit end-of-life or when lead times spike beyond your thresholds.
Cost Rollups
See total BOM cost per variant. Track cost changes across revisions.
Testing and Certifications
Test once. Trace forever.
Define test templates at the product level. Run them at the device level. Every result recorded, every certification tracked, every expiry date monitored.
Structured test templates (pass/fail, range, text, checkbox)
Test case libraries per product
Device-level test reports
Certification tracking (FCC, CE, UL, FDA)
Certification expiry alerts
Compliance document linking
