Questions
How big is the Myco mini host pcb PCB?
It measures 53.5 × 138.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Myco mini host pcb use?
36 parts, built around the BH1750FVI-TR, SHT40-AD1B-R2, XC9145B33CMR-G and MAX40203AUK+T. 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 Myco mini host pcb KiCad files?
From the ludodefgh/PlantSensor repository on GitHub, at the commit this page was made from: the board is hardware/myco-mini-host-pcb/myco-mini-host-pcb.kicad_pcb and its schematic hardware/myco-mini-host-pcb/myco-mini-host-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Myco mini host pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask ludodefgh before reusing the design.
