The postmarketOS and Alpine Linux Conference

postmarketOS hardware CI at scale
2026-09-25 , 5053.1 (Großer B-IT Raum)

This talk covers the reasoning behind automated Hardware in the Loop (HiL) testing of standard pmos devices.
Recap of the design process and preliminary setup of a hardware in the loop (HiL) testing rig designed for scaling into a test farm with dozens of devices.

The talk and slides will be in English.


This talk tells a story of how we took a reliable test setup for single device testing and scaled it up to potentially handle dozens of devices with reasonable per-device cost.
I will cover:

  • Finding and testing reliable power supplies
  • designing and building reusable physical mounting for various devices under test (DuT)
  • keeping everything compact and reliable
  • Adapting a DuT for automated testing
  • How to stay motivated in case nothing goes to plan

hk is an electronics engineer from southern Germany.
He used to work in hardware prototyping and later switched to test automation.
In his hackspace he built an automated postmarketOS hardware testing rig.
