Esp32 breakout
dcowden/esp32_breakout_board
The xc board logs data from an nrf52840 and sends it to an esp32 , which processes further. The board needs: 1. esp32 devkit c ( we need all the pins) (38 pin) 2. seed xiao nrf52840 (14 pin) 3.

It measures 228.6 × 123 mm and has 2 copper layers, 1.6 mm thick.
213 parts, built around the AUX6. 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.
From the rileytuttle/order66-pcb repository on GitHub, at the commit this page was made from: the board is order66/order66.kicad_pcb and its schematic order66/order66.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask rileytuttle before reusing the design.
