Questions
How big is the MainsFrequencyMonitor PCB?
It measures 65 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MainsFrequencyMonitor use?
38 parts, built around the ESP32-WROOM-32, HLK-5M03, EL357N(C)(TA)-G and 10D561K. 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 MainsFrequencyMonitor KiCad files?
From the Qeteshpony/MainsFrequencyMonitor repository on GitHub, at the commit this page was made from: the board is pcb/MainsFrequencyMonitor.kicad_pcb and its schematic pcb/MainsFrequencyMonitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainsFrequencyMonitor design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
