It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
51 parts, built around the CH340C, LM1117DT-3.3, SM4001 and LL4148. 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 MatheusCipolotti/STM32_Codes repository on GitHub, at the commit this page was made from: the board is DEV_BOARDS/STM32F030K6T6/Hardware/STM32_DEV_BOARD/STM32_DEV_BOARD.kicad_pcb and its schematic DEV_BOARDS/STM32F030K6T6/Hardware/STM32_DEV_BOARD/Fonte.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 MatheusCipolotti before reusing the design.
