Questions
How big is the IoT Launch Kit PCB?
It measures 26.4 × 54.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IoT Launch Kit use?
28 parts, built around the CH340G, LD1117S33CTR-HXY and S8050. 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 IoT Launch Kit KiCad files?
From the bjpirt/IoT-Launch-Kit-PCB repository on GitHub, at the commit this page was made from: the board is IoT-Launch-Kit.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the IoT Launch Kit design in my own project?
Its repository states no licence, so its author keeps all rights: ask bjpirt before reusing the design.
