Hardware is the work most software companies pretend not to do — because hardware does not forgive shortcuts the way software does. Mutex Systems delivers hardware engineering across IoT, embedded systems, PCB design, firmware, point-of-sale terminals, industrial automation, and edge AI devices. Where digital meets the physical world.
Shipped devices in shops, hospitals, factories, vehicles, and field operations across the UK, Pakistan, and the GCC — including the hardware behind Mutex Fintech POS.
IoT device engineering, embedded systems, firmware, PCB design, POS terminals, industrial automation, edge AI, hardware certification, and new product introduction.
Connected devices from concept to production
Full-lifecycle IoT device engineering — from connectivity architecture to cloud integration — designed to survive the real environments devices actually operate in.
Microcontroller-based products and modules
Embedded systems built for the constraints that matter — power budget, memory footprint, real-time response, and long-term maintainability.
Real-time, low-power, and safety-critical firmware
Firmware written to be maintainable by a team that did not write it — documented, unit-tested, and version-controlled from the first commit.
Schematic, layout, prototyping, and small-to-medium production
PCB design from schematic capture through layout, design rule checks, and prototype assembly — with DFM considered from the first layer stack decision.
Mechanical design, materials selection, human-factors
Enclosure design that satisfies IP ratings, thermal requirements, assembly constraints, and the need to look appropriate for the environment it operates in.
Card and crypto-ready POS hardware
The hardware behind Mutex Fintech POS — our own crypto-ready payment terminal. Card-present, NFC, and QR payment hardware engineered for reliability in high-transaction environments.
Retail, hospitality, and public-sector kiosks
Kiosk hardware designed for the environment it will actually live in — vandal resistance, 24/7 reliability, remote management, and accessibility compliance.
Sensors, controllers, and gateways for commercial property
Smart building device design for occupancy, energy, environmental, and access management — integrated with BMS and cloud analytics platforms.
Shop-floor automation and SCADA connectivity
Industrial IoT hardware that bridges the gap between the plant floor and digital systems — connecting legacy PLCs and SCADA systems to modern analytics and control platforms.
ISO 13485-aware design and IEC 62304 firmware
Medical-grade device design aligned to ISO 13485 quality management and IEC 62304 software lifecycle requirements — designed for the standards, not around them.
On-device inference for vision, audio, and sensor analytics
Edge AI hardware that runs inference locally — reducing latency, cloud costs, and privacy exposure compared to cloud-dependent AI deployments.
GPS, BLE, LoRaWAN, NB-IoT trackers for fleet and logistics
Asset and fleet tracking hardware designed for long battery life, reliable connectivity in poor signal environments, and tamper-evident installation.
Environmental, industrial, and structural monitoring at scale
Sensor network hardware and infrastructure for large-scale monitoring deployments — designed for long-term reliability in demanding physical environments.
Production tooling and quality control fixtures
Purpose-built tooling and test fixtures for production lines — designed to speed up assembly, reduce operator error, and ensure consistent quality at volume.
Cloud-managed firmware updates and device telemetry
Device management infrastructure that keeps firmware current and devices observable — without requiring physical access to deployed units.
CE, FCC, RoHS, and compliance from schematic stage
Design-for-compliance from the schematic — catching certification risks before they become costly redesigns at the test laboratory.
Recovering, replacing, or extending discontinued hardware
Legacy hardware revival — recovering schematics from physical boards, replacing obsolete components, and extending firmware for devices whose original design files no longer exist.
Environmental, EMC, vibration, drop, and lifecycle testing
Hardware QA beyond bench testing — environmental chambers, vibration rigs, drop tests, and EMC pre-compliance testing to reduce the risk of first-article certification failures.
Component sourcing, BOM optimisation, and risk reduction
Supply chain guidance for hardware products — component selection that balances cost, availability, lead time, and long-term lifecycle risk.
Secure elements, TPMs, and HSM integration
Hardware-rooted security for devices handling sensitive data or operating in adversarial physical environments — cryptographic keys that cannot be extracted from a stolen unit.
From bench prototype to first production run
New product introduction support from first prototype bring-up through design validation, production validation, and the first production run.
Every hardware engagement delivers a complete technical package — design files in your hands, test evidence ready for certification submission, and manufacturing documentation your production partner can act on without us in the room.
Discuss a Hardware ProjectHardware engagements follow a five-phase model. Most begin with a paid feasibility and specification phase — two to four weeks — producing a requirements specification, BOM estimate, and fixed-scope quotation for subsequent phases.
Paid, 2–4 week phase. Requirements specification, architecture sketch, BOM estimate, risk analysis, and fixed-scope quotation.
PCB schematic, layout, firmware architecture, enclosure design, and DFM review — iterating with you at each major design checkpoint.
Prototype bring-up, functional testing, pre-certification testing, and design iterations — until DVT criteria are met.

Straight answers about IoT device engineering, PCB design, hardware certification, and how hardware projects engage.
What hardware does Mutex Systems actually build?
IoT devices and connected products, embedded systems and microcontroller-based products, industrial sensors and gateways, point-of-sale terminals (including the Mutex Fintech POS with crypto settlement capability), self-service kiosks, smart-building devices, asset trackers and fleet telematics devices, wearables, medical-grade devices, edge AI hardware, and custom tooling and jigs for production lines. We also provide PCB design, firmware engineering, and full-lifecycle support from concept through manufacturing.
Can you take us from concept to shipped product?
Yes. Our hardware engagements run across five phases: feasibility and specification, design and schematic, prototype and validation, production run, and ongoing support and OTA update. Most engagements begin with a paid feasibility phase — two to four weeks — that produces a requirements specification, architecture sketch, BOM estimate, and risk assessment. This gives you a written fixed-scope quotation before any significant engineering investment is made.
Do you do PCB design and assembly?
Yes. We use Altium Designer and KiCad for schematic capture and PCB layout. Our PCB work covers multi-layer designs, high-speed digital, RF, mixed-signal, and power electronics. For prototype assembly we work with trusted electronics manufacturing partners and can coordinate small-to-medium production runs. DFM (design for manufacture) considerations are built into the layout process rather than addressed as an afterthought before production.
Can you support CE, FCC, RoHS, and other hardware certifications?
Yes. We design for compliance from the schematic stage — catching EMC, safety, and radio issues before they become expensive failures at the test laboratory. We provide CE Marking support across the Radio Equipment Directive, Low Voltage Directive, EMC Directive, RoHS Directive, and Machinery Directive depending on product type. For FCC we support Part 15 compliance and test laboratory coordination. We manage all test laboratory liaison and prepare the technical file and declaration of conformity.
Do you build IoT devices with cloud connectivity?
Yes. Our hardware and cloud practices work together on IoT projects — the hardware team designs the device and its connectivity, and the cloud team builds the backend infrastructure, device management platform, and data analytics layer. We have delivered IoT projects connecting to AWS IoT Core, Azure IoT Hub, and custom MQTT brokers, using LoRaWAN, NB-IoT, Wi-Fi, BLE, and cellular connectivity depending on the power, bandwidth, and range requirements of the specific application.
Can you reverse-engineer or extend legacy hardware?
Yes. Legacy hardware work typically involves recovering schematics from physical PCB inspection and analysis, identifying obsolete components and sourcing modern alternatives, extracting and analysing existing firmware where required, and extending the hardware and firmware for new requirements. This is common for manufacturing clients with production equipment whose original supplier has ceased trading, or for clients acquiring businesses with undocumented hardware assets.
Do you build edge AI devices?
Yes. Our edge AI hardware work covers NVIDIA Jetson platforms for computer vision and inference-heavy workloads, Google Coral with Edge TPU for power-efficient inference, Hailo accelerators for embedded vision applications, and microcontroller-class neural accelerators including STM32 with CubeAI and Nordic Semiconductor. We handle model optimisation for edge deployment using TensorFlow Lite and ONNX, as well as the hardware bring-up and integration of the inference pipeline with the surrounding device firmware.
