It measures 55.2 × 76.5 mm and has 4 copper layers, 1.6 mm thick.
130 parts, built around the Z0103MN, TPS61040DBV, AMS1117-3.3 and DW01A. 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 qqq0/STM32_Based_Multimeter repository on GitHub, at the commit this page was made from: the board is PCB KiCad/STM32_Multimeter_PCB/STM32_Multimeter_PCB.kicad_pcb and its schematic PCB KiCad/STM32_Multimeter_PCB/STM32_Multimeter_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 qqq0 before reusing the design.
