Questions
How big is the Bb panel PCB?
It measures 35 × 35.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bb panel use?
23 parts, built around the ATTINY13A-SSU, DRV8701PRGE and IRF7351TRPBF. 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 Bb panel KiCad files?
From the goktugh/robotbits repository on GitHub, at the commit this page was made from: the board is beetleback/panel/bb-panel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bb panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask goktugh before reusing the design.
