Zoomwag/Vantis-XA UAB
RowOne is an open-source printed circuit board by Zoomwag, from the Zoomwag/Vantis-X repository on GitHub. It is a 4-layer board of 99 × 70 mm with 71 parts on 86 nets, routed with 616 tracks and 3,566 vias.
It is built around the ESP32-S3-WROOM-1-N8, BMI270 and BQ24074RGTR, with the MAX-M10S, USBLC6-2SC6 and SMD1206P110TF/16 among its other parts. Its parts include 23 resistors, 22 capacitors, 7 switches, 6 ICs and 4 connectors. It belongs with the ESP32 boards of this library.
Vantis-X is a high-performance fixed-wing UAV with a custom-designed flight controller. The aircraft is designed to be fully 3D-printed, with a focus on lightweight construction and integrating the airframe and electronics into one system.
Development journal: JOURNAL.md
The aircraft has a wingspan of approximately 1 metre and an estimated all-up weight of 450 g. The design is still in development, with the airframe and flight controller being developed alongside each other.
The flight controller is being designed specifically for Vantis-X rather than using an off-the-shelf board. This includes the schematic, component selection, PCB layout and 3D modelling before manufacture.

71 parts, built around the ESP32-S3-WROOM-1-N8, BMI270, BQ24074RGTR and MAX-M10S. 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 Zoomwag/Vantis-X repository on GitHub, at the commit this page was made from: the board is Vantis/RowOne.kicad_pcb and its schematic Vantis/RowOne.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 Zoomwag before reusing the design.
