A modular, open-source smartphone built for repairability, upgradability, and hardware freedom.
Built around the MCM-iMX93 System-on-Module, PulsePhone uses Hirose DF40 board-to-board connectors across all subsystems — keeping modules isolated, swappable, and independently developable.
The Main Board is the hub of the system, hosting the MCM-iMX93 SoM, an onboard DAC, and all signal routing. Every peripheral connects to it via DF40 connectors.
| Module | Interface | Role |
|---|---|---|
| Main Board | DF40 (host) | MCM-iMX93 SoM, DAC, signal routing |
| Display Module | MIPI/LVDS + Touch | Adapter for wide MIPI-DSI display compatability. |
| Camera Module | MIPI CSI-2 | Adapter for wide MIPI-CSI camera compatability. |
| Audio Module | Analog | Amp, speaker, headphone, mic |
Full connector pinout in MBI-Lite Specification.
- One connector standard (DF40) across every module
- Linux (Debian + Phosh), Android, and Ubuntu Touch compatible
- Fully open: KiCad source + mechanical files under GNU GPL-V3.0
First prototype! Revamping design. PCB Design in final polishing and bug fix stages!
Deffered to embedded inclusion on main board.
PCB Design DONE! This module acts like an adapter, so PulsePhone can have a wide range of MIPI-DSI displays to be compatible with.
Design TBD
Design Started
Planned inclusion. This extension will include an additional DF40 on the main board for community mods to the phone, like additional features.
- Almost ready to boot something.
- Working on wrapping up design for main board.
