Questions
How big is the Bugboard mini PCB?
It measures 20 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bugboard mini use?
20 parts, built around the PRTR5V0U2X. 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 Bugboard mini KiCad files?
From the NeerajR18/bugboard-mini repository on GitHub, at the commit this page was made from: the board is PCB/bugboard-mini.kicad_pcb and its schematic PCB/bugboard-mini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bugboard mini design in my own project?
Its repository states no licence, so its author keeps all rights: ask NeerajR18 before reusing the design.
