Questions
How big is the EUPLA CONE CORE V1.1.0 PCB?
It measures 76.2 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EUPLA CONE CORE V1.1.0 use?
99 parts, built around the ARDUINO UNO R3, DAC7562SQDGSRQ1, INA114AP and MCP3208-BI/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 EUPLA CONE CORE V1.1.0 KiCad files?
From the PineConeMechatronics/EUPLA_CONE_CORE repository on GitHub, at the commit this page was made from: the board is hardware/source/EUPLA_CONE_CORE_V1.1.0.kicad_pcb and its schematic hardware/source/EUPLA_CONE_CORE_V1.1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EUPLA CONE CORE V1.1.0 design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
