Questions
How big is the UC segment control PCB?
It measures 139 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UC segment control use?
140 parts, built around the ATMEGA88PA-PN, BC548, IRLML2244 and IRLML2502. 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 UC segment control KiCad files?
From the bigdisp/scoreboard-hardware repository on GitHub, at the commit this page was made from: the board is board_schematic/uC_segment_control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UC segment control design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
