Questions
How big is the Grouch PCB?
It measures 247.6 × 108.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Grouch use?
111 parts, built around the ATMEGA32U4-AU, ATMEGA32U4-MU 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 Grouch KiCad files?
From the masonzack/Terminal repository on GitHub, at the commit this page was made from: the board is Grouch PCB/Grouch.kicad_pcb and its schematic Grouch PCB/Grouch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Grouch 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).
