PoE 模块支持:加装 Power over Ethernet 模块后,可通过网线同时供电和传输数据,简化设备部署。 3. 常见问题排查 连接失败:检查网线是否松动、路由器是否开启 DHCP、代码中的 MAC/IP 是否正确。 数据解析错误:HTTP 请求需严格遵循格式(如响应头需包含Content-Type),字符串匹配时注意大小写和特殊字符。 七、应用
Similar to the Arduino Ethernet Shield, but with a newer chipset, this ethernet shield supports both TCP and IP Protocols in TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPoE format. The RJ45 ethernet port is also low enough so... Add to Cart, Ethernet Shield for Arduino - W5500 Chipset ...
