It measures 44.5 × 21 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the MT3608 and SS34. 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 ArifRahmanEEE/IOT repository on GitHub, at the commit this page was made from: the board is MT3608 (Boost Converter) Symmetrical/mt3608 Boost Converter.kicad_pcb and its schematic MT3608 (Boost Converter) Symmetrical/mt3608 Boost Converter.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 ArifRahmanEEE before reusing the design.
