Questions
How big is the Bebl v2 PCB?
It measures 80 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bebl v2 use?
75 parts, built around the ATMEGA328-PU, TPS61221DCK, ADXL345-EP and MCP73831. 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 Bebl v2 KiCad files?
From the wyolum/bebl_v2 repository on GitHub, at the commit this page was made from: the board is kicad/bebl_v2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bebl v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wyolum before reusing the design.
