Questions
How big is the PulseCounterI2C PCB?
It measures 50.8 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PulseCounterI2C use?
35 parts, built around the 24FC01T-I/OT and PCF8593T/1. 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 PulseCounterI2C KiCad files?
From the freudenthal/PulseCounterI2C repository on GitHub, at the commit this page was made from: the board is PulseCounterI2C.kicad_pcb and its schematic DigitalIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PulseCounterI2C design in my own project?
Its repository states no licence, so its author keeps all rights: ask freudenthal before reusing the design.
