It measures 147.3 × 119.4 mm and has 2 copper layers, 1.6 mm thick.
69 parts, built around the TPS65581PWP, ERJ3EKF3300V, C0603G104K5RACT250 and 800AWSP9M2QE. 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 arsal18/HW-Lab repository on GitHub, at the commit this page was made from: the board is Project/PCB_Design/new/PCB.kicad_pcb and its schematic Project/PCB_Design/Alarm-Clock.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 arsal18 before reusing the design.
