Questions
How big is the Smd breadboard PCB?
It measures 20.4 × 38.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smd breadboard use?
8 parts, built around the CC1101RGPR. 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 Smd breadboard KiCad files?
From the vasavbn2/ECE445 repository on GitHub, at the commit this page was made from: the board is SMD_Breakout/smd_breadboard.kicad_pcb and its schematic Fob_Design_Files/Fob_Design_Files.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smd breadboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask vasavbn2 before reusing the design.
