For hardware product teams

Your Products
Deserve a System.
Beyond Spreadsheets.

S3Suite is a self-hosted platform for hardware product teams. Replaces spreadsheets, shared drives, and disconnected tools with one system covering engineering, manufacturing, and field operations.

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.

01

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.

02

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.

03

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.

04

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.

05

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.

06

The certification expired. Nobody noticed.

FCC, CE, UL compliance dates live in someone's calendar. One missed renewal and an entire product line is at risk.

Platform + Services

The Platform. Plus Managed
Services When You Need Them.

S3Suite is the platform. On top of it, we offer managed services on a recurring basis. Your team uses the tool. We handle the operations you do not want to staff for.

S3 Protocol

Device health, firmware updates,
and field support.

A lightweight communication layer. Provision at the factory. Get health metrics in real-time. Push firmware remotely. Secure per-device authentication via signed tokens.

HTTPMQTTTCP

SDKs for ESP32, STM32, Zephyr RTOS, Linux/Yocto, and Android.

How It Works

Set up in 10 minutes.
Four clear steps.

01

Create a Project

Organize by product. Every document, BOM, and firmware build belongs to a project.

02

Design and Document

Version schematics, track firmware builds, manage certifications, set up test templates.

03

Manufacture and Track

Define variants, create lots, generate devices with auto serial numbers. Test against templates.

04

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

Safety-critical traceability, OCPP compliance, remote charger monitoring, warranty tracking at scale.

Industrial Equipment

Long product lifecycles, regulatory compliance (CE/UL), field service operations, complex BOM management.

Medical Devices

FDA/CE audit trail, rigorous testing enforcement, immutable traceability from component to deployed device.

Consumer Electronics

High variant count (regional SKUs), rapid iteration cycles, production scaling, certification tracking.
