Questions
How big is the Driver PCB?
It measures 45 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Driver use?
46 parts, built around the HV9961LG-G, TLP291-4 and ESP32-H2-MINI-1U. 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 Driver KiCad files?
From the fujiy/Home repository on GitHub, at the commit this page was made from: the board is ACLamp/driver/driver.kicad_pcb and its schematic ACLamp/LEDboard/LEDboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask fujiy before reusing the design.
