Hardware Product Engineering Studio
Hardware Engineering Built to Your Target Form, Quantity, and Budget Specifications.
Provide your core functional requirements and constraints. We identify the optimal engineering path — component sourcing, prototype validation, or mass production — and execute end-to-end circuit, firmware, and mechanical engineering.

2 · Structuring Requirements
Requirements Become Technical Specifications, Unconfirmed Parameters Turn into Engineering Reviews.
We analyze form factor, target volume, budget limits, and schedule to build an initial technical specification. Gaps are resolved through engineering reviews, and initial consultations are provided at no charge.

| Your condition: 100 | 100 |
At 100 units, one unit costs about 51% of making just one.

5 · Phased Execution & Deliverables
Milestone Verification and Formal Engineering Deliverables
We share interim results and check records at every milestone and proceed only upon your approval, reducing costly redesigns later.

Typical Outsourced Development vs. Arcarix Integrated Engineering
Typical outsourcing starts from a client-prepared spec, and the first real check often comes with the physical prototype, when redesigns cost more. Arcarix refines the spec from the initial idea and reviews interim results at each milestone to reduce rework.
Typical outsourcing
- Spec drafting & quote waiting
- Contract engineer designs & builds
- First look at the assembled prototype
- ↺ Redesign and rebuild changes
- Delivery

- First integrated prototype (EVT)
- Revision · spec-line testing
- Deliverable handover
Milestone verification & approval checkpoint
- Start from just an idea
A spec or brief usually has to come first before a quote and schedule.
A sentence or two is enough for a draft spec; gaps become questions.
- Form and circuit designed together
Circuit and case are often designed separately and first meet when the prototype is assembled; problems then mean rebuilding.
Form, enclosure and circuit are designed together to the same dimensions from the start, with 3D fit checks and interim results at each step to reduce rebuilds.
- Start from set foundations
Parts and layout are chosen and drawn from scratch for each project.
We start from chip families we use often (ESP32, nRF52) and a set order of part and fit checks.
- Don’t build what already exists
A development request assumes something new is built.
If a product on the market works, we compare, check a sample and you receive it.

Quantitative testbench mapped to PRD specifications
In form-driven products (wearables and the like) the enclosure sets the board area first; in spec-driven products (sensors, industrial devices) the case is shaped around the parts and battery. Either way, form and circuit move together from the start.
