For the last few years now, we’ve all had access to tiny, affordable Systems on a Module. These wunderchips are complete Linux systems with WiFi, a halfway decent GPU, and enough memory to run a real system. This is the perfect platform to base a tablet build on, the only problem is that someone has to actually do it. The DLT One is the ‘Damn Linux Tablet’ from [Prof. Fartsparkle]. It’s the answer to the question of when someone is going to build a tablet computer around one of these cheap Systems on a Chip that are floating around.
With many modules to choose from, the first task is actually choosing one of these Linux modules. [Fartsparkle] ended up with the Nvidia Jetson Nano, an impressive little board that has one distinct advantage: it’s drop-in compatable with the Raspberry Pi Compute Module, the Raspberry Pi-on-an-SODIMM. Given a single chassis, [Prof. Fartsparkle] can simply upgrade his tablet by getting a newer version of the Jetson Nano (or the Compute Module).
The current state of the board is basically an SODIMM socket on a board, with breakouts for Ethernet, a power jack, USB, and HDMI. That’s all there is to it, and design on the tablet chassis is ongoing.
Future updates for this tablet build will include USB-C PD, an mPCI-E connector that would allow for M.2 storage, LTE in some form or another and a dock that would allow you to turn this into a Surface-like laptop. It’s an amazing build, and one of the best entries we’ve seen in this year’s Hackaday Prize.
