Questions
How big is the Ec meter PCB?
It measures 46.5 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ec meter use?
41 parts, built around the LM324. 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 Ec meter KiCad files?
From the visgence/ec-meter repository on GitHub, at the commit this page was made from: the board is ec-meter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ec meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask visgence before reusing the design.
