Questions
How big is the 0131-dcdc-3a PCB?
It measures 12 × 10 mm and has 2 copper layers, 0.8 mm thick.
What parts does the 0131-dcdc-3a use?
12 parts, built around the AP62300WU. 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 0131-dcdc-3a KiCad files?
From the CircuitMonkey/CHIPs repository on GitHub, at the commit this page was made from: the board is 0131-dcdc-3a/PCB-KiCAD/0131-dcdc-3a/0131-dcdc-3a.kicad_pcb and its schematic 0131-dcdc-3a/PCB-KiCAD/0131-dcdc-3a/0131-dcdc-3a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 0131-dcdc-3a design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
