Questions
How big is the Greenhouse controller PCB?
It measures 81 × 67 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Greenhouse controller use?
80 parts, built around the ATTINY45-20SU, ESP-12F, MP2451DT-LF-Z and TP4054. 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 Greenhouse controller KiCad files?
From the taseraul/greenhouse-controller repository on GitHub, at the commit this page was made from: the board is hardware/hardware.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Greenhouse controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask taseraul before reusing the design.
