Questions
How big is the PCB design try PCB?
It measures 261.9 × 77.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB design try use?
117 parts, built around the ATMEGA32U2-MU, CSTCE16M0V53-R0 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 PCB design try KiCad files?
From the rocket-bus/PCB_design_try repository on GitHub, at the commit this page was made from: the board is PCB_design_try.kicad_pcb and its schematic PCB_design_try.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB design try 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).
