It measures 46 × 76 mm and has 2 copper layers, 1.6 mm thick.
43 parts, built around the ESP32-WROOM-32U, MAX485ED, LM2596S-5.0 and 74HC04D. 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 dialfandi/KiCAD_Project repository on GitHub, at the commit this page was made from: the board is ESP_Lora_ESP32/ESP-Communication.kicad_pcb and its schematic ESP_Lora_ESP32/ESP-Communication.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 dialfandi before reusing the design.

Three projects live in this folder. They share NewLibrary.kicadsym, TMC2209.pretty and the same philosophy: nothing on the board needs precision placement, every active part is a module in a socket.
