在 1.0 基础上添加 TYPE-C 接口方便刷机，替换 C3 模块为乐鑫的（安信可和乐鑫关系崩了），PCB 兼容两个版本的 C3 模块，不带天线 ESP32-C3-WROOM-02U-N4（方便放入正泰模数化插座）和带天线 ESP32-C3-WROOM-02-H4 （适合不用壳 TYPE-C 供电裸奔的）

电量重置按钮的地址要和表地址一致，如果地址不是0x01，最后两位CRC校验码需要重新生成
可以在这里生成MODBUS CRC16

透传模式（有空更新）
通过 ESP 的 IP 和端口 666 透传数据，测试工具可以使用 SSCOM

Modbus 一般分 Modbus-TCP 和 Modbus-RTU 两个种，收发报文有所区别，这里不做过多介绍网上资料很多。我这里介绍 Modbus-RTU 的，Modbus-TCP 由于没有设备无法测试。一般设备厂商设备说明书里都会提供地址说明（有的可以从官网下到），直接看图
外壳和变压器安装注意做好绝缘
欢迎提交其他设备适配文件，麻烦按以上设备目录结构提交
