Everything your connected device needs — do it yourself or sit back

A connected device needs more than a circuit board: an operating system, a test at the end of the production line, a way to deliver updates and someone who closes vulnerabilities for ten years. We have a product for each of these. And if you prefer, we do the work too.

  • From the DIN-rail computer to maintenance ten years on
  • You can run every product yourself or leave it to us
  • Source code in the open, escrow updated with every major release

Overview

What a connected device needs

  • The device

    A DIN-rail computer or a single-board computer as the basis, flexible enough to meet your specific requirements too. Or we develop a device of your own for you.

  • The software on it

    A Buildroot Linux with a mainline LTS kernel, signed updates and open source code. Your team builds it or takes our image.

  • Testing in manufacturing

    At the end of the line, devices are programmed, tested and logged — at your EMS provider, at your site or at ours.

  • Operation in the field

    Monitoring devices and rolling out updates. On your own infrastructure or in our cloud in Germany.

  • Ten years of maintenance

    Monitoring, assessing and closing vulnerabilities. As regular releases with SBOM and CVE report, or as a service we take on.

Your choice

Do it yourself or sit back

The scope is the same either way. It is only a question of who does the work.

Do it yourself or sit back
CriterionYou do itWe do it
The deviceqdGate or qdSBC, with component population and variants to your specification.Hardware engineering: we develop a device of your own or adapt ours.
The software on itqdCoreX with sources and build system. Your team builds and changes it.Embedded software engineering: we build your application with you.
Testing in manufacturingqdTest, configured for your device, at your manufacturing site.Verification: we build the test setup and run it.
Operation in the fieldqdCloud on your own infrastructure.qdCloud in a German data centre, operated by us.
Ten years of maintenanceRegular releases with SBOM and CVE report. You integrate them.Systems- & Lifecycle-Management: we keep your device up to date.

You decide this for each product separately. And you can change it later: what you do yourself today, we take on tomorrow — and what we do today, you can take back at any time.

Independence

What belongs to you

  • The source code is in the open

    The Buildroot external tree and the board support are public on GitHub. You can see what the system is built from before you decide.

  • qdCloud runs at your site too

    You can operate the platform on your own infrastructure. In that case your device data never leaves your premises.

  • Escrow with every major release

    The current source code is placed in escrow with every major release, at least once a year. The escrow agent and the release triggers are set out in the supply contract.

Our products

Each one works on its own and can be moved into your own environment.

Behind it

And the services behind it

Behind every product there is a team that also delivers the same work as a service.
