Specialisation
Design office for your connected products
You have an idea for a connected product. Our engineers support you from idea to industrialised prototype: custom hardware, firmware, connectivity and certification.
From idea
to product
Designing a connected product means combining four disciplines in a single product: the measurement or control electronics, the firmware that makes it work, the radio that connects it, and the power management that makes it autonomous. At Codium, all these skills are in-house.
We work with hardware start-ups launching their first product, SMEs looking to connect existing equipment, and manufacturers who want to add value to their offering through connectivity.
There is no need to have files or technical specifications at the first discussion — we start from your functional need and build the architecture with you.
Already have IoT expertise in-house and mainly need specialist skills in radio connectivity (LoRa, LTE-M, DECT NR+, BLE)? See our IoT design office.
The 4 pillars
of a successful connected product
A connected product that works in real-world conditions must excel on four dimensions. At Codium, all of them are mastered in-house.
Schematic, PCB layout, component selection, mechanical and thermal constraints. The physical foundation of the product.
RTOS, drivers, application logic, sleep mode management. The software that makes the hardware work and talks to the network.
LoRa, LTE-M, DECT NR+, BLE, Wi-Fi — protocol selection, antenna, radio stack, cloud integration. The link between the device and the world.
Power consumption optimisation in sleep and transmission. Battery sizing, energy harvesting. A connected product must run without maintenance.
Your product's journey
Whether you start from an idea or an already validated proof of concept, Codium can take charge of the whole journey or a specific stage.
Initial discussion to understand the need, usage constraints, environment and target volume. Together we build the technical architecture and the schedule.
Validation of the principle on a development board before starting the custom PCB design. Reduces risk on innovative projects.
Schematic, PCB layout, firmware and radio stack development. Deliverables in industry-standard formats (Gerber, BOM, documented source code).
Manufacture of the first prototype, functional tests, validation of connectivity and performance. Rapid iterations until the validated version.
Technical file preparation, EMC pre-tests, CE marking. Complete manufacturing file and launch on our production line.
They entrust us with their connected product
Start-up, SME or large group — we adapt our method to your technical maturity and your context.
First electronic product, in need of a partner who handles everything. We bring the multidisciplinary team and the product development process.
→ Rapid prototyping & POCAdd connectivity to an existing machine or piece of equipment, or create a new connected product. We integrate it as well as possible into your infrastructure.
→ Industrial IoT solutionsAn idea, but no technical specification yet. We start from the functional need and build the architecture together, step by step.
→ Free initial discussionFrequently asked questions — Connected product
The questions our clients systematically ask before starting a project.
Where do I start when designing a first connected product?
It all starts with an initial discussion to define the need: use, physical constraints, environment, desired connectivity, battery life, target production volume. There is no need to have files or technical specifications — we start from your functional need.
From there, Codium draws up a technical architecture and a project schedule.
How long does it take to develop a first prototype?
For a simple connected product (a sensor with a radio and basic firmware), allow 8 to 16 weeks from design to first working prototype. A complex product (multi-sensor, multi-radio, display, optimised battery) can take 4 to 8 months.
A precise schedule is drawn up at the start of the project.
Can you build a quick proof of concept before committing?
Yes. Codium can build a proof of concept on a development board to validate technical feasibility or the measurement principle before starting the custom PCB design. It is often the right approach for innovative projects or technologies the client does not yet master.
What battery life can be achieved?
Depending on the protocol and measurement cycle, a battery life of 1 to 10 years on a battery is achievable. A LoRa node sending one measurement per hour typically consumes less than 50 µAh/day. Codium optimises power consumption from the hardware and firmware design stage.
Is CE certification mandatory for a connected product?
Yes, as soon as the product is placed on the European market. A connected product (with an embedded radio) falls under the RED directive. Codium supports you with preparing the technical file, EMC pre-tests and referral to an accredited laboratory for the final tests.
