Questions
How big is the PCF1306 PCB?
It measures 51.1 × 17.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PCF1306 use?
15 parts, built around the SN74LS157DR(LX), 74LS00SC, 74LS32SC and BBL-120-G-E. 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 PCF1306 KiCad files?
From the liveboxandy/PCF1306 repository on GitHub, at the commit this page was made from: the board is PCF1306.kicad_pcb and its schematic PCF1306.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCF1306 design in my own project?
Its repository states no licence, so its author keeps all rights: ask liveboxandy before reusing the design.
