Electronics & hardware product development in Barcelona
from 0 to production

End-to-end product development: electronics, firmware and mechanical design.
From idea to manufacturable product.

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.

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.

Industry: Industrial Printing / Test Equipment
  • BLDC motor drive
  • Automated open/close cycling
Test Equipment Motor Control Reliability Testing

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 3D-Printed Test Jigs and Bed-of-Nails Fixtures
Client: Opotek (internal tools)
Industry: Production Test / Manufacturing
  • ESD-safe printed parts
  • Pogo-pin bed of nails
Test Fixtures 3D Printing ESD Production Test

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.

We've partnered with startups and established companies across various industries to bring their hardware visions to life.
