Questions
How big is the OpenBeacon2 PCB?
It measures 130 × 110 mm and has 4 copper layers, 1.6 mm thick.
What parts does the OpenBeacon2 use?
261 parts, built around the AVR128DA48-E/PT, 24AA64T-I/OT, OW2EL89CENUXK7YLC-25M and CC0805KRX7R9BB104. 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 OpenBeacon2 KiCad files?
From the etherkit/OpenBeacon2 repository on GitHub, at the commit this page was made from: the board is pcb/OpenBeacon2.kicad_pcb and its schematic pcb/OpenBeacon2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenBeacon2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask etherkit before reusing the design.
