Questions
How big is the DriverBoard PCB?
It measures 44.4 × 8.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DriverBoard use?
27 parts, built around the 74AHCT1G125SE, TPS92510DGQ, RT9058-50GV and SS24. 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 DriverBoard KiCad files?
From the zephray/X61-Backlight-Mod repository on GitHub, at the commit this page was made from: the board is DriverBoard/DriverBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DriverBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask zephray before reusing the design.
