End-to-end hardware, firmware, and software development for a microfluidics control system used in medical research. Integrated sensor arrays, precision fluid and temperature control, and real-time data acquisition with wireless connectivity.
About
Opotek is a Barcelona-based engineering studio. Consulting engineer Oriol Pascual leads and engineers every project, working with specialist partners (mechanical design, machining, certification labs) when a project needs them.
We take care of the whole product: electronics, firmware, software and mechanical design,
and we make sure it all works together on real hardware, not just on paper.
You receive tested, validated files that are ready for production.
What we do best
We build complete embedded hardware systems: schematics, PCB design, enclosure CAD, prototyping, and system integration. You get production-ready deliverables (manufacturing files, test documentation and a sourced BOM) and, if you need them, the physical product too: working prototypes or manufactured units.
- Concept to working prototype. Complete system design: electronics, firmware, and enclosure integrated from day one for your MVP.
- Validation builds. EVT builds, bring-up, iteration, and validation.
- Production support. Test fixtures, programming jigs and DFM/DFT review before the first production run.
- Embedded systems. MCU/RTOS firmware, drivers, and wireless connectivity for IoT (BLE, Wi-Fi, LoRa, GNSS, LTE-M/NB-IoT).
- AI and machine learning. On-device inference (edge AI), sensor fusion and signal processing, plus AI models built on your product’s data, such as anomaly detection and classification.
- Industrial automation. PLC programming, custom controllers, motor drives, sensing and operator controls for machines and industrial processes.
- Turnkey delivery. Coordinated mechanical, electrical, firmware and software in one integrated product.

Projects
Selected projects. No two projects are alike, so each one is scoped as its own case, and detailed documentation is shared under NDA when a client requires it.
Complete product development for a therapeutic massage device using targeted light therapy and controlled heating. Delivered electronics design and firmware for a manufacturable MVP.
Edge ML system for real-time fault detection and predictive maintenance of industrial induction motors. Developed sensor integration, on-device inference pipeline, and anomaly detection algorithms for early failure prediction.
Adapter that connects industrial multifunction testers with banana-plug leads to equipment fitted with CETAC (IEC 60309) connectors, so electrical tests can be run directly on that equipment.
Induction motor driver for industrial use, developed end to end: power stage, control firmware and protection functions.
Interactive educational device for teaching mathematics through hands-on learning. Embedded system generates adaptive math problems using statistical analysis, creating a physical “smart dice” learning tool.
Automated feed dispensing system for equestrian competitions. End-to-end development: sourcing, mechanical design (timed-release latch mechanism), electronics, firmware, and IoT connectivity for precise, scheduled feeding.
Human presence detection system using mmWave radar sensors for smart fitting rooms. End-to-end development: hardware design, firmware, and integration with IoT platforms to allow real-time occupancy monitoring.
- 85 kV output
- Current-controlled
- Fiber-optic control link
Current-controlled 85 kV high-voltage power supply for a CosmoCaixa exhibit. Controlled over a fiber-optic link for full galvanic isolation, with support for live visualization of the experiment.
- BLDC motor with FOC
- Programmable tactile feedback
BLDC motor-based control knob with tactile feedback that lets visitors control industrial stroboscopes in a particle-movement simulation exhibit at CosmoCaixa.
- BLDC motor drive
- Automated open/close cycling
Automated test bench that opens and closes the door of an industrial large-format printer again and again with a BLDC motor, to verify the door's lifetime before the printer goes into production.
- ESD-safe printed parts
- Pogo-pin bed of nails
Programming jigs and bed-of-nails test fixtures built from ESD-safe 3D-printed parts. Printing them in-house cuts fixture cost and lead time, so boards reach production testing sooner.
