Questions
How big is the Mushroom pcb PCB?
It measures 96.4 × 100.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mushroom pcb use?
57 parts, built around the ESP32-WROOM-32E, LM2596S-5.0, ME6211C33M5G-N and AO3400A. 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 Mushroom pcb KiCad files?
From the karenquezada/MushROOM repository on GitHub, at the commit this page was made from: the board is Hardware/mushroom_pcb.kicad_pcb and its schematic Hardware/mushroom_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mushroom pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask karenquezada before reusing the design.
