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 ...
使用ArduinoEthernet类库需要有相应的硬件支持。下面是常见的3种支持Ethernet功能的硬件。1.Ethernet扩展板Ethernet扩展板（图19-1）是集成WIZnetW5100网络芯片的扩展 板。将扩展板连接到Arduino后，可使Arduino具有网络功能。同时扩展板还集成了SD卡卡槽，以配合SD卡库读/写SD卡。19.1Ethernet相关硬件介绍 2.Arduino...
