Questions
How big is the Lcd cnt PCB?
It measures 69.4 × 21.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lcd cnt use?
30 parts, built around the 74HC595, 74HCT08D, MP1540DJ and M2.5. 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 Lcd cnt KiCad files?
From the dilshan/yali repository on GitHub, at the commit this page was made from: the board is design/lcd-cnt.kicad_pcb and its schematic design/lcd-cnt.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lcd cnt 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).
