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。 -…
Yes. The symbol is EasyEDA_Cloud:CH9340K and the footprint EasyEDA_Cloud:ESSOP-10_L4.9-W3.9-P1.00-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
