Questions
How big is the Macro1 PCB?
It measures 69.9 × 42.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro1 use?
30 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Macro1 KiCad files?
From the keltoncmcgrath/TestMacro1 repository on GitHub, at the commit this page was made from: the board is macro1.kicad_pcb and its schematic macro1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask keltoncmcgrath before reusing the design.
