It measures 58 × 32.5 mm and has 2 copper layers, 1.6 mm thick.
49 parts, built around the ESP32-S3-WROOM-1-N4, 05A20L24P and MBR0530. 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 Kandles11/eink-pcb repository on GitHub, at the commit this page was made from: the board is eink-pcb.kicad_pcb and its schematic eink-pcb.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 Kandles11 before reusing the design.

The ESP32-S3 uses 3.3V. I want onboard indicator LEDs, and the option to have offboard LEDs as well. Using addressable WS2812-type LEDs is flexible. These need a 5V supply.
