Questions
How big is the ScribblesBoard PCB?
It measures 50 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ScribblesBoard use?
31 parts, built around the ATMEGA328P-MU, BNO055, MIC5205-3.3YM5 and CSTCE8M00G55-R0. 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 ScribblesBoard KiCad files?
From the etran/ScribblesPCB repository on GitHub, at the commit this page was made from: the board is ScribblesBoard/ScribblesBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ScribblesBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask etran before reusing the design.
