The hardware journey, simplified

8 structured stages from concept to mass production. One point of contact per project; molding, assembly and test in the Shenzhen factory.

01 Concept and feasibility

We start by understanding your product vision, target market, and business model. Our team conducts a technical feasibility study covering component availability, power budget, connectivity requirements, form factor constraints, and regulatory landscape. You receive a comprehensive project plan with timeline, budget, and risk assessment.

Key deliverables

  • Feasibility report
  • Project plan & budget
  • Risk assessment
  • Component pre-selection
02 Industrial design

Our design team creates the physical form of your product — from initial sketches and mood boards to photorealistic 3D renders and ergonomic studies. We balance aesthetics, user experience, and manufacturability to create a design that looks great and can be produced at scale.

Key deliverables

  • Concept sketches
  • 3D CAD models
  • Photorealistic renders
  • CMF (Color, Material, Finish) spec
03 Electrical engineering

Schematic design, PCB layout, and firmware development for your product's electronic brain. We design for reliability, EMC compliance, and power efficiency from the start. Our team handles everything from simple microcontroller circuits to complex multi-board systems with wireless connectivity.

Key deliverables

  • Schematic & PCB layout
  • Firmware source code
  • Power budget analysis
  • EMC pre-compliance test
04 Mechanical engineering

Detailed mechanical design of enclosures, structural components, and internal assemblies. Every part is designed for the target manufacturing process — injection molding, die casting, sheet metal, or CNC. DFM analysis ensures your parts are optimized for production from day one.

Key deliverables

  • Production-ready CAD
  • Tolerance analysis
  • DFM/DFA report
  • Assembly instructions
05 Prototyping and validation

Functional prototypes built using production-representative processes. We run EVT (Engineering Validation Test) and DVT (Design Validation Test) cycles to verify all functional, environmental, and reliability requirements. Each iteration is scoped and scheduled in the project plan.

Key deliverables

  • Functional prototypes
  • EVT/DVT test reports
  • Design iteration log
  • Golden sample approval
06 Tooling and pilot production

Production tooling fabrication and pilot production run (PVT). This validates the entire manufacturing process at scale — yield, cycle time, quality metrics, and supply chain. The pilot run produces the Golden Sample for your final sign-off before mass production.

Key deliverables

  • Production tooling
  • Pilot run samples
  • Process validation report
  • Quality control plan
07 Certification path

The certification path is planned from the feasibility study. We design for it, run EMC/RF pre-scans in DVT, build DVT units for the test lab and supply the documents it asks for. You or a test lab you choose make the FCC, CE or UL submission.

Key deliverables

  • Pre-scan results
  • DVT units for the lab
  • Lab document pack
  • Compliance matrix
08 Mass production and fulfillment

Full-scale manufacturing with ongoing quality management. We handle everything from component procurement and SMT assembly to final packaging and global logistics. Direct shipping to your warehouse, Amazon FBA, or end customers.

Key deliverables

  • Production units
  • Quality reports (SPC)
  • Inventory management
  • Global logistics

Frequently asked questions

How much does it cost to develop a new hardware product?

It depends on complexity: a single-board sensor with an off-the-shelf enclosure and a multi-board consumer product with custom tooling are different projects. We do not publish a range, because a range wide enough to be true would not help you budget. The feasibility study is a paid first step at a published tier, and it produces an itemized cost breakdown for your product. The free engineering review of what you send comes before it.

How long does the entire process take from concept to production?

Three things move it most: how many certifications the product needs, whether it needs custom tooling, and how many validation cycles the design takes to settle. None of those is known before the feasibility study. That study produces a dated plan for your product, and the official quote restates it. We do not put a number on it before we have seen the product, because a number given then is a guess.

What connectivity protocols do you support for IoT products?

We have deep expertise in Wi-Fi (802.11 b/g/n/ac/ax), Bluetooth/BLE (5.0, 5.3, Mesh), Cellular (Cat-M1, NB-IoT, LTE), LoRaWAN, Zigbee/Thread/Matter, and Sub-GHz (433/868/915 MHz). We also handle cloud platform integration (AWS IoT, Azure IoT, custom MQTT) and OTA firmware update systems.

How do you handle the transition from prototype to production?

A hardware product has three transitions at once, electronics, mechanical and firmware, and most of the risk is in them disagreeing. The same engineers carry all three through EVT, DVT and PVT in the Shenzhen factory and attend each build in person. After PVT you sign the golden sample, and production is held to it. Nothing is handed to a new supplier.

Can you help with firmware development and cloud integration?

Yes. Our firmware engineers write embedded software for ARM Cortex-M, ESP32, Nordic nRF and other platforms, including RTOS integration, wireless stacks, power management, OTA updates and cloud connection. OTA updates are designed to verify each image and fall back to the last good one. Firmware source is delivered when the order includes it; otherwise you receive binaries.

When in the project does certification actually happen?

The certification path is in the project plan from the feasibility study. We design for it, build DVT units for the lab and supply the documents it asks for; you or a test lab you choose make the FCC, CE or UL submission.

What are the typical MOQs for production?

It depends on whether the product needs custom tooling: a tool has to be amortised over a run, and an off-the-shelf enclosure does not, so the two have very different floors. The quantity your product actually needs is set in the project plan and restated in the official quote. We offer blanket orders and quarterly releases either way, to help manage inventory and cash flow.

How do you protect my intellectual property?

We sign your NDA before the first call, and project files live in private project storage. On engineering projects, design files and IP are assigned to you at hand-off. Tooling you pay for belongs to you. Production units ship with debug ports locked.

How do you optimize battery life for IoT products?

Battery optimization is a system-level challenge. We address it at every layer: hardware (low-power component selection, power gating, efficient DC-DC converters), firmware (sleep modes, duty cycling, efficient protocol usage), and connectivity (BLE vs. LoRa vs. cellular based on data requirements). Battery life is a design outcome rather than a specification we can promise before seeing the duty cycle, so it is modelled during the feasibility phase and stated in the project plan.

Can you work with our existing engineering team?

Yes. Some teams have no hardware engineers, some have one generalist, and some need a specialist for FPGA, RF and antenna, power electronics, motor control or embedded Linux. You might keep the firmware while we design the hardware, or keep the industrial design while we handle the mechanical engineering and production.
