FOUNDER

Daniel Kjellström

Founder — senior electronics engineer. Hardware design, system architecture, embedded software.

Over 10 years designing hardware that reached production: multi-sensor IoT devices, AR/VR optics electronics, EV charging power electronics and maritime RF base stations. Work spans high-speed digital, RF and power design on 4–10 layer boards and flexible circuits, and the full CE marking process from standards selection through in-house EMC pre-compliance to the Declaration of Conformity.

PROFILE
  • Experience — 10+ years in electronics and embedded development
  • Based in Stockholm, Sweden
  • Previously CEO and co-founder of Devward, a deeptech building-automation startup
  • Full CE process ownership: standards selection, testing, technical file, Declaration of Conformity
Domains
  • IoT and building automation
  • AR/VR and eye tracking
  • EV charging and power electronics
  • Maritime RF and telecommunications
  • Consumer appliances
Technologies
  • 4–10 layer PCB and flexible circuit design (Altium)
  • High-speed interfaces — MIPI, DDR3, Gigabit Ethernet, LVDS
  • Isolated AC/DC and DC/DC power conversion up to 11 kW
  • RF and antenna design, 2,4 GHz, Wi-Fi, BLE, 802.15.4, Wi-Fi HaLow, 4G
  • EMC pre-compliance — conducted and radiated emissions, immunity
  • Embedded C/C++ on ARM, ESP32, nRF52 and AVR

Selected work

Work delivered by our founder as an independent contractor, before Polar ProLabs. Shown as engineering track record, not as Polar ProLabs client engagements.

Saab TransponderTech

R60 AIS/VDES base station

Contribution: Electronics design

A shore-based maritime base station for AIS and VDES, the digital successor to AIS. Board-level electronics for equipment that has to run continuously in a coastal installation.

CTEK

Njord Go

Contribution: Electronics; embedded software for production tooling, test and energy-meter calibration

Electronics for an EV charging product, plus the embedded software behind its production tooling — end-of-line test and energy-meter calibration.

Devward
