基于上述原因，诞生了这个项目，解决了上面的问题，并具有以下特点： - 超小尺寸，超高集成度，仅比开发板长1mm。 - 整合接口，仅用一个Type-C接口实现充电与程序下载。 - 集成最最最重要的电池保护芯片。 - 预留电池引脚接口和开关引脚接口，锂电池不再直连3.3V引脚，而是会先经过降压芯片降压后输出。 - 智能切换供电，在有外部USB供电的情况下会切断锂电池供电并进行充电，断开供电后自动使用锂电池供电。 -…

Questions

How big is the LED Assy PCB?

It measures 90 × 8 mm and has 2 copper layers, 1.2 mm thick.

What parts does the LED Assy use?

27 parts, built around the BSS138PS and CJ3401. 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 Assy KiCad files?

From the SATXcircuitmakers/UniversalBadge repository on GitHub, at the commit this page was made from: the board is LED_Assy/LED_Assy.kicad_pcb and its schematic LED_Assy/LED_Assy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the LED Assy design in my own project?

Its repository states no licence, so its author keeps all rights: ask SATXcircuitmakers before reusing the design.
