Questions
How big is the LED PCB PCB?
It measures 121.5 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED PCB use?
48 parts, built around the SMD110PL-TP. 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 LED PCB KiCad files?
From the freevoltage/LED_BAR_Prusa_Mini repository on GitHub, at the commit this page was made from: the board is LED_PCB.kicad_pcb and its schematic LED_Breakoutboard/LED_Breakoutboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask freevoltage before reusing the design.
