Questions
How big is the LCC Booster PCB?
It measures 90 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LCC Booster use?
84 parts, built around the 6N137S-TA1-L, CL31A106KBHNNNE, AC0402FR-071K43L and ERJ6ENF4702V. 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 LCC Booster KiCad files?
From the TechModelRailroadClub/System4 repository on GitHub, at the commit this page was made from: the board is hardware/LCC_Booster/LCC_Booster.kicad_pcb and its schematic hardware/LCC_Booster/LCC_Booster.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LCC Booster design in my own project?
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).
