Questions
How big is the Hydro PCB?
It measures 78 × 46 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hydro use?
69 parts, built around the ESP-12E, TPS562200DDCR, DRV8825PWP and TPS61161A. 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 Hydro KiCad files?
From the o7-machinehum/Hydroponic repository on GitHub, at the commit this page was made from: the board is ee/hydro/hydro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hydro design in my own project?
Its repository states no licence, so its author keeps all rights: ask o7-machinehum before reusing the design.
