Questions
How big is the Cerebra 1.4 IPS PCB?
It measures 60.2 × 95.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cerebra 1.4 IPS use?
109 parts, built around the ATMEGA328-PU, ATTINY85-20PU, VXO7805-1000 and MCP6024-I/P. 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 Cerebra 1.4 IPS KiCad files?
From the spamatica/Cerebra_328_IPS_PCB repository on GitHub, at the commit this page was made from: the board is Cerebra 328 IPS PCB v1.4/Kicad/Cerebra 1.4 IPS/Cerebra 1.4 IPS.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cerebra 1.4 IPS 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).
