Questions
How big is the Chirstmas Card PCB?
It measures 106 × 148 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chirstmas Card use?
86 parts, built around the STM32G030C6T6, MHT151WDT, CC0402KRX7R9BB104 and KH-6X6X5H-STM. 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 Chirstmas Card KiCad files?
From the emaneric/Electronic-Christmas-Card repository on GitHub, at the commit this page was made from: the board is PCB/Chirstmas-Card.kicad_pcb and its schematic PCB/Chirstmas-Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chirstmas Card 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).
