It measures 47 × 77.5 mm and has 2 copper layers, 1.6 mm thick.
11 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 sudesh41/current-_sensor-PCB repository on GitHub, at the commit this page was made from: the board is current_sensor.kicad_pcb and its schematic current_sensor.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 sudesh41 before reusing the design.
