Questions
How big is the LEDbacklight PCB?
It measures 136 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LEDbacklight use?
177 parts, built around the 74HC245D, TLC5955DCA, AD9708AR and LMV601. 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 LEDbacklight KiCad files?
From the JasonLiJT/HDR-backlight-PCB repository on GitHub, at the commit this page was made from: the board is LEDbacklight/LEDbacklight.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LEDbacklight design in my own project?
Its repository states no licence, so its author keeps all rights: ask JasonLiJT before reusing the design.
