Questions
How big is the Ee115-capstone PCB?
It measures 115.8 × 98.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ee115-capstone use?
191 parts, built around the ESP32-C3-WROOM-02-N4, OPA705PA, AD8038AR and MIC4605-2YM-TR. 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 Ee115-capstone KiCad files?
From the tsaimatthew/ee115-capstone repository on GitHub, at the commit this page was made from: the board is ee115-capstone.kicad_pcb and its schematic ADC-MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ee115-capstone design in my own project?
Its repository states no licence, so its author keeps all rights: ask tsaimatthew before reusing the design.
