+
+## 描述
+
+<mark>LAN底座</mark>是集成了以太网芯片W5500的底座，目的是提供给有让M5Core接入有线网络需求的用户。因为M5Core集成了无线WIFI，能接收无线热点的网络，可是没有网络接口，如果你需要让M5Core接入有线网络来工作的话，这个LAN底座正好合适，而且LAN底座还配备了磁铁和滑动杆，方便你装置LAN和M5Core到壁面上。
+
+另外LAN底座还有橙色HT3.96端子，这个接口还没有电气连接，它连接不同Pin脚的时候，可以实现对应的Pin拓展。如果你需要这个接口变成RS485的拓展接口的话，那么使用配套的排针和TLL转RS485功能小板子焊接到LAN底座上面，即可实现RS485接口，从而可以通过这个HT3.96端子，通过RS485协议控制M5Core的整个功能。
+
+如果TLL转RS485的功能小板子与LAN底板结合的话，小板子上的串口引脚将与LAN底板的GPIO1、GPIO3(UART0)连接。
