Questions
How big is the Microgame2 PCB?
It measures 58 × 104 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Microgame2 use?
86 parts, built around the ESP32-PICO-D4, FT231XQ-R, MAX98357AEWL+T and TCA6416ARTWR. 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 Microgame2 KiCad files?
From the aherbez/audiotest repository on GitHub, at the commit this page was made from: the board is microgame2.kicad_pcb and its schematic Audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Microgame2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask aherbez before reusing the design.
