Isonoe d.o.o. · Zagreb, Croatia

Hardware, firmware, software, cloud. One team.

We build complete solutions end to end, from first prototype through certification to production. No handoffs between vendors, no integration gaps.

10,000+ Devices deployed
CE / FCC Products passed
Full stack PCB to cloud
01 / About

Most projects lose time at the seams between the hardware vendor, the firmware contractor, and the app team. We remove the seams.

Mission
We bridge the gap between ambitious ideas and working products, handling the technical complexity from early prototype to production-ready system.
Approach
No handoffs, no silos. Our engineers work across embedded firmware, PCB design, and software, so every layer is designed against the others.
Team
Engineers who have shipped products across structural health monitoring, mobility, and consumer electronics. Hands-on problem solvers, not project managers.
02 / Services

End-to-end delivery across the stack. Each layer is built by the same team that builds the others.

Software

Software that ships with the product, as part of the whole system rather than a separate deliverable.

  • Desktop & mobile 3D visualization, operator interfaces, and planning tools your users work with daily
  • Cloud platforms Dashboards, analytics, and device management that scale from 10 devices to 10,000
  • Machine learning Computer vision and pattern recognition that turns sensor data into automated decisions
  • System integration One team across hardware, firmware, and software, so there are no integration gaps and no finger-pointing

Electronics

Production-grade hardware that passes certification and ships to real users, not bench prototypes.

  • PCB to production Circuit boards designed for manufacturing, with thousands of units shipped in certified products
  • Embedded firmware Real-time firmware that runs unattended for years in the field
  • Rapid prototyping Concept to working prototype in weeks, then straight to production-ready design
  • Compliance We design for CE and FCC and run EMC pre-compliance testing on our own equipment, so products reach the accredited lab ready to pass

IoT

Connected devices that work reliably in the real world, with 10,000+ deployed and counting.

  • Sensor networks Battery-powered devices monitoring structures, vehicles, and equipment for years unattended
  • Connectivity Wi-Fi, BLE, NB-IoT, LTE-M. We pick the right protocol for your deployment, not the trendy one
  • Fleet management Monitor, update, and control thousands of deployed devices remotely, from firmware rollout to diagnostics
  • Data & analytics Real-time dashboards and alerting that turn raw sensor data into actionable insight
03 / Projects

Solutions we designed, built, and took through certification to production.

001 / Own product

GaiaPulse

Our own ecosystem of battery-powered IoT devices for structural health monitoring, built for long-term deployment in harsh environments.

  • Nexus Cloud platform unifying data from every device, with real-time visualization, alerting, and analytics
  • Sentinel Battery-powered device for long-term seismic monitoring, with GNSS time synchronization
  • Spectra Continuously analyzes the frequency response of structures to detect changes in stiffness
  • Fractis High-precision crack width monitoring for early detection of structural damage
002 / Consumer electronics

Cali's Books: Infinibook

A digital reader that keeps the tactile experience of a physical book while adding interactive audio and games.

  • Hardware Custom electronics tuned for audio quality and responsive interaction at a consumer price point
  • Firmware Architecture supporting immersive storytelling and interactive educational games
  • Connectivity Wi-Fi and BLE for content updates, data sync, and mobile app integration
  • NFC Recognition system that identifies booklets and loads the matching content automatically
003 / Mobility

Scoozer

An IoT retrofit that turns standard scooters into a connected, rentable fleet with remote monitoring and control.

  • Hardware Control module integrating with off-the-shelf scooters for authentication and remote operation
  • Firmware Reliable operation, accurate status monitoring, and power management that maximizes battery life
  • Connectivity BLE for local interaction, NB-IoT/LTE-M for fleet-wide tracking and diagnostics
  • Security Anti-theft protection with GPS tracking, geofencing, and remote lock/unlock
