Steam Machine Inkterface: Valve Open Sources the E-Ink Screen for You to Build

Valve just did something unexpected: rather than selling the Steam Machine’s e-ink screen, the company is publishing all the files you need to build it yourself. This move sums up Valve’s open hardware philosophy pretty well, and it should appeal to the maker community just as much as the Linux gaming scene.

The Steam Machine’s Open Source E-Ink Screen: the Inkterface

Valve named this accessory the “Inkterface”. It’s a faceplate equipped with a 5.83-inch monochrome e-ink display, designed to fit on the front of the Steam Machine. All design files are available on GitLab under the MIT license. Valve even included an assembly video directly in the repository.

The hardware list is precise and approachable:

1 x Adafruit ESP32 Feather with 2MB PSRAM
1 x Adafruit eInk Breakout Friend
1 x Adafruit 5.83″ Monochrome eInk Panel
13 x M2.5 x 5mm socket head screws
4 x 1/4″ x 1/4″ x 3/16″ step magnets (SB443-OUT)

Nothing outrageous on paper. An intermediate technical skill level and a modest budget are all you need to get started.

Why Valve Isn’t Selling the Screen Itself

Valve is upfront about choosing not to produce or distribute the Inkterface. The logic is consistent with the open hardware approach: hand innovation off to the community rather than managing a production chain for a niche accessory. This isn’t the first time Valve has taken this stance. The CAD files for the Steam Deck and the Index were already published the same way.

This decision leaves the door open for third-party manufacturers. JSAUX, for example, has confirmed they plan to offer ready-to-use versions called “Ink & Pixel versions”. If the Steam Machine gains traction, other accessory brands should follow.

SteamOS 3.8: the Context That Changes Everything

The Inkterface release doesn’t stand on its own. Since late June 2026, SteamOS 3.8 lets you assemble a Steam Machine from any PC components. It’s no longer a closed machine with a fixed configuration.

This shift turns the Steam Machine into an open modular platform, closer to a Linux gaming PC running the SteamOS experience. The Inkterface fits right into that logic: the faceplate becomes a customizable surface, not a fixed element.

The Technical Community’s Reaction

The reception has been enthusiastic, especially in Linux gaming and maker circles. GamingOnLinux, which closely follows the SteamOS ecosystem, covered the announcement on July 3, 2026. The Verge also picked it up for a broader audience.

On GitHub, a third-party project quickly emerged under the name xfoa/humours. It offers a partially working implementation featuring a widget displaying a rotating cube and temperature data. The community didn’t just watch: it started building.

Interest is still concentrated among a technically savvy audience. The Reddit score on r/steammachine is modest (around 14 points), which confirms this topic still reaches a niche, despite The Verge’s coverage. Hacker News and GamingOnLinux account for most of the engagement.

What This Means for the Open Source Hardware Ecosystem

Valve keeps walking the talk. Publishing complete design files under the MIT license, with an assembly video and a precise bill of materials, is a real signal to the maker community.

The open question: will accessible kits emerge to bring the Inkterface beyond experienced makers? If JSAUX delivers on its promise, the answer could come sooner than expected. And if other manufacturers step in, the Inkterface could become a de facto standard for customizing the Steam Machine.
