It measures 52.5 × 62.6 mm and has 2 copper layers, 1.6 mm thick.
42 parts, built around the ESP32-WROOM-32E, AP62300TWU, AMS1117-3.3 and BC847. 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 perumalelectro/NFC_PROJECT repository on GitHub, at the commit this page was made from: the board is nfc_circuit.kicad_pcb and its schematic nfc_circuit.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 perumalelectro before reusing the design.
