Electronic circuit design
Schematic design, component selection, validation and design reviews.
Sole proprietorship • Norway
Electronics design that is ready for production.
From idea to PCB, firmware and prototypes — with production-ready deliverables and clear documentation.
Circuit + PCB design
Firmware (Arduino/ESP)
3D print prototyping
Production-ready
Gerber, BOM, Pick & Place, drills and clear documentation.
3D models
STEP/3D exports so you can fit electronics into your enclosure fast.
Practical support
Component sourcing, revisions and improvements when the market changes.
Services
I help companies and makers turn ideas into robust electronics — with predictable deliverables.
PCB design
2–8+ layer PCB layout, EMC-minded routing, DFM and clean documentation.
Firmware development
Arduino/ESP32/ESP8266 and embedded workflows — from prototype to stable releases.
3D PCB modelling
STEP exports and mechanical integration support for your enclosure design.
Prototyping & 3D printing
FDM and MSLA printing for quick iteration on enclosures and fixtures.
From idea to production
I can guide the full process: requirements → prototype → pilot → production files.
How I work
A simple process that keeps progress predictable.
- 1) Clarify requirements & constraints
- 2) Design + reviews (schematic/PCB)
- 3) Prototype + test (HW/FW)
- 4) Production package + handover
Deliverables
Typical handover package (adjusted to your manufacturer and workflow).
- Gerber + drill files (manufacturer-ready)
- BOM with alternates and sourcing notes
- Pick & Place / centroid files
- Assembly drawings + polarity/critical notes
- 3D STEP model of PCB + keepouts
- Firmware source + build notes (when relevant)
- Test points / programming headers plan
- Revision log + recommended next steps

Projects
A small selection of work and prototypes.
About
I started Fjeldberg Tech as a hobby project in 2018. Today I help clients with everything from electronics design to prototypes and production handover.
I have worked with electronics and mechatronic systems for many years, from practical service work to advanced embedded systems — including energy meters and wearable devices.
