Questions
How big is the LEOS radio PCB?
It measures 100.1 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LEOS radio use?
27 parts, built around the E22-900M30S, MCP2562FD-E/P, MCP2518FDT-E/SL-HX and CL21A226MAYNNNE. 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 LEOS radio KiCad files?
From the VIP-LES/leos-radio-pcb repository on GitHub, at the commit this page was made from: the board is LEOS-radio.kicad_pcb and its schematic LEOS-radio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LEOS radio design in my own project?
Its repository states no licence, so its author keeps all rights: ask VIP-LES before reusing the design.
