Questions
How big is the Pmic dev PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pmic dev use?
93 parts, built around the ATMEGA168P-20AU, WEMOS D1 MINI, DMG2301L and DMG2302U. 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 Pmic dev KiCad files?
From the zhiyb/test_dev_board repository on GitHub, at the commit this page was made from: the board is pcb/pmic_dev.kicad_pcb and its schematic pcb/esp8266.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pmic dev design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
