Questions
How big is the Custom ESPC5 PCB?
It measures 63.5 × 57.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Custom ESPC5 use?
47 parts, built around the ESP32-C5-WROOM-1U, LM317DCYR, TJA1051TK/3/1 and SP0503BAHTG. 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 Custom ESPC5 KiCad files?
From the MARS-UVA/Custom-ESP-Board repository on GitHub, at the commit this page was made from: the board is custom-espc5-board/Custom-ESPC5.kicad_pcb and its schematic custom-espc5-board/Custom-ESPC5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Custom ESPC5 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MARS-UVA before reusing the design.
