Questions
How big is the LEDController PCB?
It measures 85 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LEDController use?
89 parts, built around the TPS54202DDC, SN74LVC8T245PW, LM66100DCK and USBLC6-2SC6. 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 LEDController KiCad files?
From the Handkep/LEDController repository on GitHub, at the commit this page was made from: the board is KiCad/LEDController.kicad_pcb and its schematic KiCad/LEDController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LEDController design in my own project?
Its repository states no licence, so its author keeps all rights: ask Handkep before reusing the design.
