nanoESP32-S2
nanoESP32-S2介绍
nanoESP32-S2 是MuseLab基于乐鑫ESP32-S2系列模组推出的开发板，板载USB转串口，TYPE-C、全彩LED，引脚兼容官方开发板，同时引出调试烧录串口和ESP32-S2本身的USB接口，更方便日常的开发测试。

demo说明
预置的出厂测试固件源码位于demo目录下，上电之后预期RGB LED应该会开始闪烁，两个TYPE-C接口一个为CH340 USB，用于调试下载，另一个为ESP32-S2的USB，若插入ESP32-S2 USB，预期会出现一个名为"ESP32-S2 MSC"的的U盘以及一个CDC串口设备。 固件编译参考：
