From Concept to
Production-Scale IoT.
Our in-house R&D team designs custom IoT devices from scratch — hardware, firmware, cloud integration, and deployment. No outsourcing. Full-stack engineering.
Built to Last
Every RAMAC device is engineered from the ground up — custom PCBs, embedded firmware, and ruggedised enclosures designed to perform in harsh field environments.
Custom Test Jigs. Real Production Testing.
We engineer custom test jigs for device manufacturers — built on LabVIEW and C/C++ — and run their production testing in-house.
We design and build custom test jigs for clients who manufacture electronic devices but don't want to build the test infrastructure themselves. Each jig is purpose-built around the product under test — hardware fixturing, electrical interface, automated test sequencing, and a full pass/fail report flow.
Our test jig stack
- LabVIEW (National Instruments) for high-level test orchestration, reporting, and operator UI.
- C / C++ for low-level device communication, calibration routines, and timing-critical test sequences.
- In-house hardware design for fixtures, harnesses, and interface boards — built to fit your DUT exactly.
Once a jig is in operation, we can run the production testing on it too — at our facility, on our team's time. Clients ship boards; we ship tested, certified product back, with full per-unit traceability.
Full-Stack IoT Engineering
Every layer of the IoT stack, designed and built in-house.
Hardware Design
Schematic design, PCB layout, component selection, and prototype manufacturing. From single sensors to complex multi-board systems.
Firmware Development
Embedded C/C++ firmware for STM32, Nordic, and ESP platforms. OTA updates, power management, and protocol implementation.
Cloud & Software
Device management platforms, mobile apps, APIs, and dashboard development. The RAMAC Portal and Cerebro App are built entirely in-house.
Deployment
Production testing, quality assurance, field installation, and ongoing maintenance. 40,000+ devices tested monthly.
Our Process
From Idea to Deployed Product
A structured process that takes concepts from first discovery through design, prototyping, validation, and scalable deployment.
Discovery
Requirements, constraints, feasibility, risk review, and project scoping.
Design
System architecture, electronics, firmware, mechanical, and UX design alignment.
Prototype
Rapid development, proof-of-concept builds, hardware bring-up, and iteration.
Validate
Testing, refinement, environmental checks, functional verification, and readiness review.
Scale
Production preparation, deployment support, lifecycle planning, and continuous improvement.

Engineering FAQs
Does G-Matrix design and manufacture its own products?
Yes. G-Matrix is a full electronic design house that develops its own hardware, firmware, and software in-house, and manufactures and tests at production scale rather than reselling third-party devices.
My use case isn't listed — can G-Matrix still help?
Yes. Beyond its standard solutions, G-Matrix engineers custom IoT solutions from scratch. If your monitoring, tracking, or control challenge isn't covered by an existing product, contact the team to scope a tailored solution.
Does G-Matrix build custom IoT products?
Yes. G-Matrix is a full electronic design house that builds custom IoT hardware, firmware, and software from concept to production — whether you need a prototype to validate an idea or a production-ready device.
What does G-Matrix's engineering process look like?
G-Matrix typically moves from discovery and design through prototyping, testing, and production. Rapid prototyping, including 3D printing, lets ideas be validated quickly before committing to manufacture.
Can G-Matrix do rapid prototyping?
Yes. G-Matrix uses in-house rapid prototyping, including 3D printing, to turn concepts into testable hardware quickly, shortening the path from idea to validated design.
What technologies does G-Matrix work with?
G-Matrix works across ARM and STMicroelectronics microcontrollers and connectivity including Sigfox, Bluetooth LE, and GPS/GNSS — covering hardware design, firmware, and software integration.
Can G-Matrix manufacture and test at volume?
Yes. G-Matrix runs production-scale manufacturing and testing, with over 40,000 units tested monthly using multinational-standard test jigs to ensure quality and reliability.
Can G-Matrix develop both the hardware and the software?
Yes. As a full-stack design house, G-Matrix develops electronic hardware, embedded firmware, and the supporting software and integrations, so a project can be delivered end to end by one partner.
Who is G-Matrix's engineering service for?
It suits OEMs needing custom hardware, companies needing IoT integration, and organisations needing bespoke monitoring or control devices that aren't available off the shelf.
Can G-Matrix integrate IoT data with our existing systems?
Yes. Because G-Matrix builds the software layer as well as the devices, it can discuss integrating device data and alerts with your existing systems or platforms. Contact the team to scope your integration needs.
