Questions
How big is the Back pcb PCB?
It measures 40 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Back pcb use?
118 parts, built around the 74LS125DC, 24C32, LM339 and MCP23017-E/SS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Back pcb KiCad files?
From the ZeroPhone/ZeroPhone-PCBs repository on GitHub, at the commit this page was made from: the board is back_pcb/back_pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Back pcb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).

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.
