Questions
How big is the Waterpump PCB?
It measures 100 × 65.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Waterpump use?
18 parts, built around the 74HCT245 and AZ943-1CH-5DE. 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 Waterpump KiCad files?
From the huettner94/pcb repository on GitHub, at the commit this page was made from: the board is waterpump/pcb/pcb.kicad_pcb and its schematic waterpump/pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Waterpump design in my own project?
Its repository states no licence, so its author keeps all rights: ask huettner94 before reusing the design.
