Questions
How big is the WroomMINI2 PCB?
It measures 26.7 × 106.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WroomMINI2 use?
30 parts, built around the ESP32-WROOM-32. 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 WroomMINI2 KiCad files?
From the ccadic/wroom2keyring repository on GitHub, at the commit this page was made from: the board is WroomMINI2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WroomMINI2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ccadic before reusing the design.
