Questions
How big is the Lkt100a1 PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lkt100a1 use?
455 parts, built around the 74HC245D, TJA1042T, RS8751XF and LM324. 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 Lkt100a1 KiCad files?
From the bronzewang/escope repository on GitHub, at the commit this page was made from: the board is lkt100a1/lkt100a1.kicad_pcb and its schematic lkt100a1/lkt100a1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lkt100a1 design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
