Six engineering pillars, one accountable team
Every discipline below sits inside Ambimat. That is the point of the structure: there is no integration gap between the board, the firmware and the build.
Embedded Hardware
Architecture and component selection, schematic design and PCB layout, power and grounding, signal integrity, and EMI/EMC-conscious design through to production-ready files.
Firmware
Production-grade firmware for resource-constrained devices: RTOS and bare-metal, device drivers, protocol stacks, secure boot and over-the-air update readiness, diagnostics and validation.
Wireless & IoT
Connected products across short-range, mesh and cellular links — 2.4 GHz, Wi-Fi, Zigbee, LoRa and Sigfox, NB-IoT and CAT-M1, GPS/GNSS, with RF and antenna integration.
NFC / RFID
A long-standing contactless practice: NFC reader and tag hardware, UHF and RFID design, antenna and matching-network design, fare-collection hardware and smart labels.
Embedded Security
Hardware-rooted device identity designed in from the start: secure element integration, key protection, firmware authenticity, encrypted device-to-cloud channels and tamper-aware design.
Productisation & Manufacturing
The path from a working prototype to a build that repeats: industrial design and enclosure, test and QA/QC, design for manufacturability, supply chain, box build and packaging.
Alongside these, Ambimat develops the mobile and cloud layer that most connected products need — Android and iOS applications, cloud APIs, device onboarding, MQTT and HTTPS communication, dashboards and firmware update flows.
From concept to a box-packaged product
Ambimat takes a product through the full sequence, and a customer can join it or leave it at any step. Most engage for part of it.
1 · Concept
Requirement, architecture and the decisions that set the cost and the risk.
2 · Design
Schematic, PCB layout, mechanical and industrial design.
3 · Develop
Embedded firmware, mobile applications and cloud services.
4 · Prototype & QA
Functional builds, test, iteration and quality control.
5 · Compliance
Compliance-oriented design and test support, working to FCC, CE and PTCRB requirements on customer programmes.
6 · Manufacture
Design for manufacturability, supply chain, box build and packaging.
Compliance outcomes are properties of a specific customer product assessed on its own terms, not a property of Ambimat or of any Ambimat module.
Ambimat Legacy
Established in April 1982, Ambimat Electronics has spent 44 years turning an electronics requirement into a product that can be manufactured. Ambimat works in both OEM and ODM models for public sector units, private enterprises and start-ups.

More on the Why Ambimat? page.
How we work with OEMs
A complete product programme
Concept to manufacture, with one organisation accountable across hardware, firmware, RF and the build.
A single engineering stage
Architecture, hardware, firmware or test, taken on its own where the rest of the programme sits elsewhere.
Design-in around a module
Integration support for AmbiTap or AmbiConnect B22 in the customer’s own product.
Migration and re-engineering
Reworking an existing design — cost, supply, obsolescence or localisation.
The product a customer ends up with is theirs. Ambimat supplies the engineering and the hardware; it is not a network operator and does not run deployed connectivity, fleets or IoT networks.
