Questions
How big is the Junebug PCB?
It measures 50.8 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Junebug use?
33 parts, built around the STM32L496RGT3, IS25LP128F-JBLA3, CC0603JPX7R9BB104 and CC1206CRNPO9BN4R7. 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 Junebug KiCad files?
From the CMUAbstract/junebug repository on GitHub, at the commit this page was made from: the board is kicad/junebug.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Junebug design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
