Questions
How big is the RB Macro16 PCB?
It measures 102 × 118 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RB Macro16 use?
73 parts, built around the ATMEGA32U4. 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 RB Macro16 KiCad files?
From the Bragendesh/RB-Macro16 repository on GitHub, at the commit this page was made from: the board is KiCad Project/RB-Macro16.kicad_pcb and its schematic KiCad Project/RB-Macro16.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RB Macro16 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
