Questions
What parts does the Full Circuit use?
76 parts, built around the R-78E3.3-0.5, TEC 2-1219WI, L293D and 74HC595. 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 Full Circuit KiCad files?
From the EthanSousaProjects/CBR_Custom_Cluster repository on GitHub, at the commit this page was made from: the board is Code_And_Circuits/Full_Circuit/Full_Circuit.kicad_pcb and its schematic Code_And_Circuits/Full_Circuit/Data_Display_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Full Circuit 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).
