This is a breakout board for the XIAO ESP32C3 and the XIAO RP2040.
The intent is to use these boards to implement a wifi modem firmware on the ESP32C3, and to speak to it using the RP2040 as a USB-to-UART+SPI adapter.
The initial plan is to implement a melpo service that acts as a SPI port, but tunnels the communication via USB to the RP2040, similar to (or perhaps exactly like) pretty-hal-machine.

Questions
How big is the Esp32c3-wifi dev PCB?
It measures 79.5 × 31.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32c3-wifi dev use?
14 parts. 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-wifi dev KiCad files?
From the tosc-rs/mnemos repository on GitHub, at the commit this page was made from: the board is hardware/esp32c3-wifi-dev/esp32c3-wifi-dev.kicad_pcb and its schematic hardware/esp32c3-wifi-dev/esp32c3-wifi-dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32c3-wifi dev design in my own project?
Its repository publishes it under the Apache-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).
