Questions
How big is the RiverMesh PCB?
It measures 56.1 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RiverMesh use?
26 parts, built around the ESP32-S3-WROOM-1U-N4 and MAX77801ETP+. 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 RiverMesh KiCad files?
From the Qadriga/RiverMesh repository on GitHub, at the commit this page was made from: the board is RiverMesh.kicad_pcb and its schematic ESP_MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RiverMesh design in my own project?
Its repository states no licence, so its author keeps all rights: ask Qadriga before reusing the design.

NOTE: the latest PCB had been manufactured was v2.0. But it had the Gimbal ZH-connector reversed. The schematics and PCB drawing had been updated to v2.1 to fix that. But v2.1 had not been really manufactured yet.
