Questions
How big is the Bluetera PCB?
It measures 18.1 × 18 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bluetera use?
41 parts, built around the BC840, LIS2MDL, ICM-42605 and SP0504BAJTG. 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 Bluetera KiCad files?
From the ioteratech/bluetera-hardware repository on GitHub, at the commit this page was made from: the board is Bluetera.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bluetera design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
