It measures 25.6 × 24.6 mm and has 2 copper layers, 1.6 mm thick.
61 parts, built around the TLV70033DDCR-MS, TLV70018DDCR-MS, SD0805S020S0R5 and SS-53000-001. 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 Nold360/LibreHDMI repository on GitHub, at the commit this page was made from: the board is KiCAD/LibreHDMI.kicad_pcb and its schematic KiCAD/LibreHDMI.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 Nold360 before reusing the design.

Luxera One is a from-scratch attempt to build what the big labs keep teasing: AR glasses that look like actual glasses. Everything — compute, batteries, optics, sensors, audio — seals inside a chunky acetate frame.
lnls-sirius/SPIxCONV
This project consists of an 18-bit analog input (ADC) and output (DAC) within a range of 20 V (± 10 V) and 32 digital pins that can be either as inputs or outputs.
