Practical guides on IoT hardware design, firmware development, product certification, and bringing connected products to market.
From Our Engineering Team
Concrete advice based on real products we've built and shipped.
From working prototype to production-ready product
A working prototype still needs evidence from reliability tests, conformity assessment and pilot production. Learn what to check before selling.
PCB design costs: what belongs in your quote?
What determines the cost of a custom PCB? A practical guide to requirements, design files, prototype assembly, testing and comparing engineering quotes.
Hardware design: size, battery life, performance and cost
Small size, long battery life and frequent updates affect each other. Learn how to define usage scenarios and make practical hardware design choices.
How to test a hardware idea before investing heavily
Test technical feasibility, usability and demand before committing to a custom hardware product. A practical guide to choosing the next experiment.
From breadboard to PCB: when is your prototype ready?
Moving a working electronics prototype to a custom PCB? Define the requirements, interfaces and acceptance tests before committing to board layout.
Hardware development stages: PoC, EVT, DVT and PVT
What do PoC, EVT, DVT and PVT prove? Follow the stages from an initial idea to repeatable hardware production, with clear decisions at each step.
Hardware development costs: what should you budget?
What does custom hardware development cost? Michaël Devid explains the €50,000–€150,000 planning range, phased investment and costs beyond engineering.
How IoT Devices Get Tested on a Production Line
Four test stages stand between a soldered board and a shipped product: AOI, ICT, functional test and end-of-line. What each one catches, and how we run them.
Building JOGO: a football sensor that hides in the insole
How we put a sensor under a player's foot without them feeling it: an ultra-thin PCB, an antenna tuned to work through a foot, and shot analysis on the IMU.
CE and FCC in Plain Words: When You Can Sign It Yourself
Nobody hands you a CE certificate — you sign it. The rule that decides whether you can sign alone or need a notified body, worked through on an LTE-M tracker.
The Cyber Resilience Act: what to do before September 2026
From 11 September 2026 you have 24 hours to report a vulnerability being exploited in your product. Who it applies to, and what's worth doing this year.
From working prototype to CE-certified production
Your prototype works — that's the easy part. What stands between it and a product you can legally sell in Europe: directives, testing, and the technical file.
CE certification for IoT devices: the whole path
A practical guide to CE marking for connected hardware: which directives apply, what goes in the technical file, and which pre-compliance tests save money.
Building MedeMeter: solar-powered environmental sensing
How we built a solar-powered outdoor sensor that measures noise and air quality with on-device psychoacoustic AI — and which problems actually turned out hard.
