Questions
How big is the SilkScreen Field Reference Example PCB?
It measures 40.6 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SilkScreen Field Reference Example use?
7 parts, built around the ESP32-WROOM-32D, AMS1117-3.3 and SK6812MINI-E. 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 SilkScreen Field Reference Example KiCad files?
From the lcooldong/Kicad_Study repository on GitHub, at the commit this page was made from: the board is SilkScreen_Field_Reference_Example/SilkScreen_Field_Reference_Example.kicad_pcb and its schematic 24V_5V_StepDownModule/24V_5V_StepDownModule.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SilkScreen Field Reference Example design in my own project?
Its repository states no licence, so its author keeps all rights: ask lcooldong before reusing the design.
