It measures 32.4 × 52.7 mm and has 2 copper layers, 1.59 mm thick.
32 parts, built around the PDSE1-S5-S5-D, FT231XS-R, USBLC6-2SC6 and PCM13SMTR. 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 zemonkey/Isolated_UART repository on GitHub, at the commit this page was made from: the board is Isolated_UART.kicad_pcb and its schematic Isolated_UART.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 zemonkey before reusing the design.

This is my rendition of the uTerm2-S by Just4Fun (https://hackaday.io/project/181583-uterm2-s-a-multi-emulation-color-rs232-terminal). My one is in SMD, and I hopefully made it easily hand-solderable for everyone.
