From the project
This page contains the software used in the open hardware smartphone (libresmartphone)
This is gamma version. It's WIP and is going to be sent to production soon (as soon as last TODOs are finished). You can already order this board, but it's possible the I2C GPIO expander pin mapping is going to change. Also, before ordering, please make sure the Gerber files are recent (if they're up-to-date after latest commits concerning PCB files) and regenerate them if necessary.
