Questions
How big is the EPICS elephant project PCB?
It measures 101 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EPICS elephant project use?
34 parts, built around the ESP32-DEVKITC-VE, LM324N, LM358AD and AD620ANZ. 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 EPICS elephant project KiCad files?
From the Tennsei/EPICS_Elephant_Detection_Project repository on GitHub, at the commit this page was made from: the board is EPICS elephant project/EPICS elephant project.kicad_pcb and its schematic EPICS elephant project/EPICS elephant project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EPICS elephant project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tennsei before reusing the design.
