Questions
How big is the Esp32c3 fpga PCB?
It measures 81.7 × 31.8 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Esp32c3 fpga use?
94 parts, built around the ICE5LP4K-SG48I, ESP32-C3-MINI-1, DRTR5V0U4S and CPDU5V0. 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 Esp32c3 fpga KiCad files?
From the ICE-V-Wireless/ICE-V-Wireless repository on GitHub, at the commit this page was made from: the board is Hardware/esp32c3_fpga.kicad_pcb and its schematic Hardware/esp32c3_fpga.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32c3 fpga design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
