Questions
How big is the Ads b PCB?
It measures 98 × 98 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ads b use?
53 parts, built around the BLB01, LC76G, CC0402JRNPO9BN101 and CC0402JRNPO9BN120. 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 Ads b KiCad files?
From the beam-ttm/simulaciones repository on GitHub, at the commit this page was made from: the board is sonnet/adsb_patch/source/ads-b.kicad_pcb and its schematic diseno_final_patch_1090/kicad/ads-b.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ads b design in my own project?
Its repository states no licence, so its author keeps all rights: ask beam-ttm before reusing the design.
