Questions
How big is the MicLightV2 PCB?
It measures 84 × 103 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MicLightV2 use?
130 parts, built around the STM32F072CBU6, NCR321UX, UA78M33CKVURG3 and JK3030AWT-P-H40EA0000-N0000001. 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 MicLightV2 KiCad files?
From the Daxxn/MicLightV2_PCB repository on GitHub, at the commit this page was made from: the board is MicLightV2.kicad_pcb and its schematic MicLightV2-LEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicLightV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Daxxn before reusing the design.
