Questions
How big is the ValveServoI2C PCB?
It measures 107.9 × 82.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ValveServoI2C use?
156 parts, built around the BD6222HFP-TR, PCF8575DB and 24FC01T-I/OT. 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 ValveServoI2C KiCad files?
From the freudenthal/ValveServoI2C repository on GitHub, at the commit this page was made from: the board is ValveServoI2C.kicad_pcb and its schematic DigitalIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ValveServoI2C design in my own project?
Its repository states no licence, so its author keeps all rights: ask freudenthal before reusing the design.
