For hardware product teams
Your Products
Deserve a System.
Not Spreadsheets.
S3Suite brings engineering, manufacturing, and field operations into one platform. Stop firefighting. Start shipping.
What Is S3Suite?
S3Suite is a product lifecycle platform built by RnD Square for hardware teams. It replaces spreadsheets, shared drives, and disconnected tools with a single system that covers engineering documentation, manufacturing tracking, and field operations. Every device gets full traceability from first schematic to last firmware update.
Built from the patterns observed across 50+ real product deployments since 2018. We kept solving the same problems manually: lost firmware binaries, untraceable serial numbers, manual RMA tracking, and zero visibility into devices after deployment. So we built S3Suite.
Sound familiar?
Every hardware team
hits the same wall.
The BOM is in Excel. The schematics are on someone's laptop.
Firmware binaries live on a shared drive named FINAL_v3_REAL.bin. Nobody's sure which version shipped last quarter.
A device fails in the field. Now what?
Two hours digging through emails to find the lot number, firmware version, and who tested it. Then someone asks for the test report.
Warranty claims come in on WhatsApp.
The RMA tracker is a Google Sheet that three people update inconsistently. Returns pile up. Root causes stay unknown.
Firmware updates mean sending a tech to site.
No remote update path. No health monitoring. A $2 sensor failure becomes a $2,000 truck roll.
Production scales. Tracking doesn't.
500 devices were manageable. 5,000 breaks everything. Serial numbers collide, test records go missing, lot traceability is a myth.
The certification expired. Nobody noticed.
FCC, CE, UL compliance dates live in someone's calendar. Maybe. One missed renewal and an entire product line is at risk.
One platform. Three suites.
Everything your team needs.
Nothing it doesn't.
Engineering Suite
Design. Version. Certify.
Every schematic, firmware build, and test report versioned and linked to the product it belongs to.
- Document templates
- Firmware version control
- Schematic management
- BOM with health scoring
- Certification tracking
- Test templates (pass/fail, range, text, checkbox)
- Golden sample registry
- Manufacturing Vault
Manufacturing Suite
Build. Track. Ship.
From variant V1 to V17. Every lot tracked. Every device serial-numbered. Every test recorded.
- Production variants
- Bill of Materials
- Lot management with threads
- Auto serial numbers
- Device-level test reports
- Packaging management
- Vendor directory
- Send to Vendor (auto-suggest files)
Operations Suite
Deploy. Monitor. Support.
Devices in the field don't go dark. Track health, manage warranties, handle RMAs, push OTA updates.
- Device health dashboard
- Warranty management (bulk actions)
- RMA with 5-Why root cause analysis
- OTA firmware updates
- Connectivity monitoring
- Support ticketing (bi-directional)
- Knowledge Base (auto-suggest)
- AI Assistant
S3 Protocol
Devices That
Talk Back.
A lightweight communication layer. Provision at the factory. Get health metrics in real-time. Push firmware remotely. One token per device, lifetime validity.
SDKs for ESP32, STM32, Zephyr RTOS, Linux/Yocto, and Android.
Your firmware engineer can implement it in a day.

}How It Works
Set up in 10 minutes.
Not 10 weeks.
Create a Project
Organize by product. Every document, BOM, and firmware build belongs to a project.
Design and Document
Version schematics, track firmware builds, manage certifications, set up test templates.
Manufacture and Track
Define variants, create lots, generate devices with auto serial numbers. Test against templates.
Deploy and Support
Integrate S3 Protocol, push OTA updates, monitor device health, process RMAs.
Who It's For
Hardware teams shipping
500 to 50,000 devices.
IoT Product Companies
Firmware versioning, device health monitoring, OTA updates, fleet traceability across multiple SKUs.
EV Charger OEMs
