Boards using the TP4057
117 boardsBoards in 94 GitHub repositories, designed in KiCad, that use the TP4057 by TECH PUBLIC (-40℃~+85℃ 1 25uA 4.24V 4V~6.5V Charging IC Lithium Battery Not supported SOT-23-6 Battery Management ROHS). See how each wires it, with its parts, size, README and files; the TP4057’s symbol, footprint and pinout are on its own page.

SlimeVR Tracker
CoreanXka/SlimeVR-Tracker
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。 -…
