Questions
How big is the LCSDR PCB?
It measures 100 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LCSDR use?
197 parts, built around the MCP3202-CI/P, TDA2822M/TR, 74AHC1G04SE and 24C16. 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 LCSDR KiCad files?
From the licheegh/LCSDR repository on GitHub, at the commit this page was made from: the board is hardware/main/main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LCSDR design in my own project?
Its repository states no licence, so its author keeps all rights: ask licheegh before reusing the design.
