Questions
How big is the Esp pmc PCB?
It measures 25.7 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp pmc use?
27 parts, built around the TPL5111EVM and TPS63020DSJR. 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 Esp pmc KiCad files?
From the ldab/esp-battery-pmb repository on GitHub, at the commit this page was made from: the board is KiCad/esp_pmc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp pmc 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).
