This project is part of From Schematic to PCB: Layout Fundamentals Course
It measures 48.5 × 45 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the CD4033BE, HDSP-7401 and NE555P. 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 Diinidu12/Simple_Seven_segment_Counter repository on GitHub, at the commit this page was made from: the board is seven_segment_counter_Circuit/seven_segment_counter_Circuit.kicad_pcb and its schematic seven_segment_counter_Circuit/seven_segment_counter_Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
