2. It allows flexibility with multiple operating systems, including Ubuntu and Lineage OS, emphasizing Linux compatibility.
3. The device supports various storage options with a PCIe Gen 2 M.2 socket and a user-replaceable battery for sustainability.

Following a fruitful crowdfunding effort for the Brax3 privacy-conscious smartphone, which gathered over two million dollars and delivered more than 5,500 units in September 2025, Brax is returning with the Open_Slate 2 in 1.

Hardware Overview

Currently, only product images are available, but the hardware specifications have been mostly settled. It features a MediaTek Genio 720 CPU and a Mali-G57 MC2 GPU, with options of either 8 GB or 16 GB of LPDDR4X and 5X RAM. Storage options include either 128 GB or 256 GB.

The device is expected to come with a 12-inch 1600 x 2400 Gorilla Glass IPS touchscreen that supports stylus input with 4096 levels of pressure sensitivity. Connectivity options are set to include Wi-Fi 6E, GPS, Bluetooth 5.3, along with hardware privacy switches. While 5G support is not yet confirmed, it is anticipated to be available via an external module. A variety of accessories, such as folio cases and keyboards, are also promised.

Operating System Flexibility

Similar to the Brax3, the Open_Slate sets itself apart by allowing multiple operating systems, including Ubuntu, Ubuntu Touch, Debian, iodeOS, Lineage OS, and BraxOS. Braxtech states that they are:

directly collaborating with Linux integrators and chipset suppliers to guarantee adequate mainline Linux compatibility

and are also incorporating community feedback to guide the product’s evolution.

The Open_Slate is expected to feature various I/O options, including two USB Type-C ports, one of which will support Display Port 1.4.

Storage and Sustainability

The introduction of a PCIe Gen 2 M.2 socket should provide access to numerous fast storage choices (alongside the Micro SD slot), enabling convenient dual-boot functionality. The user-replaceable battery underscores a commitment to sustainability and the right-to-repair, at least as long as components can be bought.

Even though the product hasn’t reached the crowdfunding phase yet (and all the same warnings apply to supporting a product that hasn’t been shipped), the pre-order price of $399 for the basic model may attract interest. The company’s history of actually delivering products might give some assurance to early backers.

With various open-source tablets available, like the Purism Librem 11 and Pine64 Pinetab2, plus numerous Intel-based tablets (like this Chuwi Hi10 x2 – Available on Amazon) that already support Linux installations, it remains to be seen if Brax can thrive in such a competitive market.
