DFRobot原廠 POE以太網絡擴展板 Ethernet and PoE-W5500 (DFR850)For Arduino®
配送清單：
- Ethernet & PoE shield for Arduino-W5500 x1
- 2.54開口跳線帽 x1
W5500以太網擴展板是DFRobot Ethernet家族的新成員，其集成PoE電源和W5500以太網芯片，能夠滿足一般IoT項目的應用要求。其PoE供電、以太網傳輸、IO擴展，為一根網線部署IoT項目打下堅實基礎。
在性能上，W5500 集成了TCP/IP 協議棧，10/100M 以太網數據鏈路層（MAC） 及物理層（PHY），使得用戶使用單芯片就能夠在他們的應用中拓展網絡連接。支持全硬件TCP/IP協議棧，支持TCP,UDP,IPv4,ICMP,ARP,IGMP 以及PPPoE 協議。內嵌32K 字節片上收發緩存以供以太網包處理。這將會比其他嵌入式以太網方案，更加快捷、簡便。此外W5500主控板使用了一個新的高效SPI協議，支持80MHz通信速率，從而能夠更好的實現高速網絡通訊。而且W5500還提供了網絡喚醒模式（WOL）及掉電模式，能夠有效減少系統能耗，供客戶更方便的選擇使用。
在外形和功能擴展上，W5500 PoE以太網擴展板集成了符合IEEE 802.3at行業標準的PoE Class 0電源，MicroSD卡座以及標準的Gravity-4 Pin I2C接口2個，UART 接口1個，Gravity-3 Pin數字模擬接口各4個，產品大小與UNO尺寸相等。

The W5500 Ethernet expansion board is a new member of the DFRobot Ethernet family. It integrates PoE power supply and W5500 Ethernet chip, which can meet the requirements of general IoT projects.
The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. It enables users to have Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC, and PHY are embedded. The Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. W5500 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. It’s faster and easier way rather than using any other Embedded Ethernet solution. Besides, the W5500’s SPI supports 80MHz speed and a new efficient SPI protocol for high-speed network communication. In order to reduce the power consumption of the system, W5500 provides WOL (Wake on LAN) and power-down mode.
With the same size as Arduino UNO, this W5500 Ethernet expansion board adopts IEEE 802.3at standard-compliant POE Class 0 power classification and offers MicroSD card socket and 2 standard Gravity-4Pin I2C ports, 1 UART, 4 Gravity-3Pin digital ports and 4 analog ports, etc.
Functionally compatible with Arduino Ethernet Shield 2
