Questions
How big is the SevenSegment PCB?
It measures 74 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SevenSegment use?
39 parts, built around the 74HC595, ULN2003A and PJ-102AH. 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.
Where can I download the SevenSegment KiCad files?
From the MandusBorjesson/sevenSegment repository on GitHub, at the commit this page was made from: the board is hardware/seven_segment.kicad_pcb and its schematic hardware/seven_segment.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SevenSegment design in my own project?
Its repository states no licence, so its author keeps all rights: ask MandusBorjesson before reusing the design.
