It measures 116.5 × 82.9 mm and has 2 copper layers, 1.6 mm thick.
30 parts. 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 YashPS-code/General_ESP_Motor_Ctrl_PCB repository on GitHub, at the commit this page was made from: the board is omni_pcb.kicad_pcb and its schematic omni_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 YashPS-code before reusing the design.
