Questions
What parts does the Class2 use?
30 parts, built around the STM32G030F6P6, AMS1117-3.3, LR4054-T and WS2812B. 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 Class2 KiCad files?
From the rmd6502/coaster repository on GitHub, at the commit this page was made from: the board is Class_Example/Class2.kicad_pcb and its schematic Class_Example/Class2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Class2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rmd6502 before reusing the design.
