Pi Compute Module Powers Fully Open Smartphone

The Spirit smartphone project uses a Raspberry Pi Compute Module 5 as its core processor, combined with off-the-shelf components including a 5.5" LCD display, a Quectel EG25-GL LTE/GPS module for cellular connectivity, and a 3D-printable enclosure. The design emphasizes modularity with swappable components like the display, camera, and compute module. While the carrier board and enclosure designs are still evolving, the project aims to create a fully open-source smartphone using readily available hardware modules, with active community development ongoing.
