vgisc/ZeroPhone-PCBs1This 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.
Front prototype is an open-source printed circuit board by vgisc, from the vgisc/ZeroPhone-PCBs repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 40 × 100 mm with 87 parts on 76 nets, routed with 1,154 tracks and 229 vias.
It is built around the ATMEGA328P-AU, ESP-12E and BC847B, with the FC68125 and JUMPER3 among its other parts. Its parts include 26 capacitors, 19 resistors, 7 connectors, 5 diodes and 4 ICs. It belongs with the ESP8266 and AVR (ATmega, ATtiny) boards of this library.

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.

The 79 most common of 87 parts.
It measures 40 × 100 mm and has 2 copper layers, 1.6 mm thick.
87 parts, built around the ATMEGA328P-AU, ESP-12E, BC847B and FC68125. 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.
From the vgisc/ZeroPhone-PCBs repository on GitHub, at the commit this page was made from: the board is front_pcb/front_prototype.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
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).
