It measures 55 × 100 mm and has 4 copper layers, 1.6 mm thick.
87 parts, built around the LM358, LT3757AEDD#PBF, VNH5019ATR-E and XIAO ESP32C3. 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 humancomputerintegration/electrotactile-thermal-illusion repository on GitHub, at the commit this page was made from: the board is Hardware design/PCB.kicad_pcb and its schematic Hardware design/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 humancomputerintegration before reusing the design.
