Questions
How big is the Bicep PCB?
It measures 70 × 85 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Bicep use?
61 parts, built around the ATSAMD21G18A-AU, AP2112K-3.3, RFM95W-915S2 and DMG3401LSN. 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 Bicep KiCad files?
From the albachten/bicep repository on GitHub, at the commit this page was made from: the board is bicep.kicad_pcb and its schematic bicep.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bicep design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
