Questions
How big is the Bixi PCB?
It measures 91.4 × 91.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bixi use?
36 parts, built around the ESP8266EX and SP3481CN-L. 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 Bixi KiCad files?
From the msherman13/bixi repository on GitHub, at the commit this page was made from: the board is kicad/bixi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bixi design in my own project?
Its repository states no licence, so its author keeps all rights: ask msherman13 before reusing the design.
