The DSpi is a dual touchscreen Linux handheld powered by a Raspberry Pi Compute Module 5, a system-on-module that provides the power of Raspberry Pi 5 in a form factor ideal for handhelds. Creator borpendy has published all the relevant information about the DSpi on GitHub, including a template for the mainboard. The corresponding print templates for the case are also available, which users can then use either with a 3D printer or with a commercial service provider. At the same time, the maker points out that this is still an experimental project, so it should only be replicated by people who already have a certain amount of experience and who may be willing to further develop the device themselves.
As for the specs of the handheld, the creator gives the following description:
The DSpi is a Dual Screen Linux handheld powered by a Raspberry Pi Compute Module 5, designed primarily for DS emulation. The device features a 5000mah amp battery, Xbox pattern controller with dual analog sticks, Dual 480p DSI touchscreens, Stereo speakers and a DAC + Headphone amp. I reccomend using the Rasbian system image provided in the above files, featuring retropie for single screen systems, and melon DS for true dual screen DS emulation (System image coming soon).
