At HardFault, we build smart, wireless, and connected electronic products that bring hardware and software together into one seamless solution.
Whether you’re building a wearable, remote monitoring system, industrial dashboard, medical device, or a custom gateway — we help you design, engineer, and deliver reliable IoT products from concept to production.

Our expertise covers hardware, firmware, wireless technologies, cloud connectivity, sensor systems, and complete IoT architecture.

Why Custom IoT Development Matters

Every product is different — and off-the-shelf modules cannot match the reliability, power efficiency, or specific needs of real-world applications.

With custom IoT development, you get:

We ensure the entire wireless system — hardware, firmware, sensors, protocols, and cloud — works together smoothly.

Tailored hardware for your unique requirements
Optimized power consumption for battery-operated devices
Reliable long-range communication
Better security & control over your data
Scalable architecture ready for future growth
Freedom to customize & innovate faster

What We Build

We offer end-to-end IoT and wireless product development, including

Prototyping & Proof-of-Concept Development

Fast, engineering-accurate prototypes to validate your wireless concept, test connectivity, and verify real-world performance.

Testing, Validation & Manufacturing Support

Wireless performance testing, range optimization, EMI/EMC-friendly PCB design practices, and pilot manufacturing assistance.

Our IoT Development Process

We follow a clear, proven workflow to deliver production-ready wireless products:

Discovery, Requirements & System Architecture

We begin by understanding your use-case, constraints, wireless needs, and performance goals.
Our team then defines the complete system architecture — selecting the right microcontroller, sensors, wireless protocol, power design, and enclosure approach.

Hardware & Firmware Engineering

We design custom PCBs, RF layouts, and electronics while developing the firmware that brings the device to life.
This includes wireless stack integration, OTA support, sensor interfacing, and power optimization.

Prototyping, Testing & Refinement

We build engineering prototypes and validate real-world wireless performance, range, reliability, and power behavior.
Based on field testing, we refine the design and prepare it for small-batch manufacturing.

Pre-Production, Pilot Manufacturing & Deployment Support

Once the design is stable, we support manufacturing readiness—testing jigs, flashing workflows, documentation, and pilot builds.
We help you move smoothly from prototype to production and deployment.
