Questions
How big is the E mon PCB?
It measures 64.8 × 36.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E mon use?
41 parts, built around the CP2104EK, ESP-WROOM-02, NE555 and MMBF170. 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 E mon KiCad files?
From the michelmegens/EMonPCB repository on GitHub, at the commit this page was made from: the board is E-mon.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the E mon design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
