GPIO Hacker Board – Incomplete Help Page and Not Usable as Is

Hi everyone,

I got the GPIO Hacker Board for my Prusa printer to control things like lighting or similar accessories. Unfortunately, the official help page ( https://help.prusa3d.com) for setting up and using the GPIO board is incomplete.

There is no documentation about how to use macros, how to configure the board properly, or how to integrate it into regular printer operation. Without this information, the board is currently not usable for many practical applications.

Does anyone have more detailed information or a working setup guide? Or could someone from the Prusa team please update and complete the documentation?

Thanks a lot!

The page really is incomplete, it looks like Prusa is just ignoring it. It is really disappointing as it would be nice to have better documentation.

Yes, the help page is indeed very incomplete, but you can find useful info in this topic:

I wish Prusa would update the help page with everything you might need to make full use of the board.

RE: GPIO Hacker Board – Incomplete Help Page and Not Usable as Is

It’s frustrating when a product like the GPIO Hacker Board ships with poor or missing documentation. Without proper guidance, users can’t fully utilize its features, leaving them stuck or making mistakes that could damage the hardware. This is a classic example of why Incomplete Help can be more damaging than no help at all — it creates confusion, wastes time, and limits the product’s potential. A well-structured help page should include clear instructions, diagrams, and troubleshooting tips so users can confidently get started. Improving documentation isn’t just about support; it’s about ensuring the product delivers on its promise.
