Questions
How big is the 1u front pcb PCB?
It measures 36.2 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 1u front pcb use?
25 parts, built around the ESP-WROOM-02. 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 1u front pcb KiCad files?
From the slimcdk/lkf-smart-switch repository on GitHub, at the commit this page was made from: the board is circuits/1u-front-pcb/1u-front-pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1u front pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask slimcdk before reusing the design.
