Questions
How big is the Feather valve driver PCB?
It measures 127 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Feather valve driver use?
78 parts. 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 Feather valve driver KiCad files?
From the cbs-ntcore/feather_valve_driver repository on GitHub, at the commit this page was made from: the board is electronics/feather_valve_driver/feather_valve_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Feather valve driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask cbs-ntcore before reusing the design.
