README
readme.md陶瓷灯丝 LED
很简单的电路设计，没有什么特别值得说的
简而言之就是USB供电，通过一个限流保护开关，然后通过一个LED驱动芯片驱动4串LED，通过一个LED触摸控制芯片控制灯的亮度
焊接的时候需要注意LED的正负，我买的陶瓷灯丝LED上是有孔的一端为正，对应圆角矩形的一端为正，椭圆矩形的一端为负

Questions
How big is the LED LIGHT USB PCB?
It measures 51.8 × 14.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED LIGHT USB use?
23 parts, built around the SY6280AAC and SS14. 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 LIGHT USB KiCad files?
From the TheBadZhang/LED-LIGHT-USB repository on GitHub, at the commit this page was made from: the board is main.kicad_pcb and its schematic main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED LIGHT USB design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheBadZhang before reusing the design.
