DESCRIPTION
Integrate your MicroMod project into an Ethernet network including Power-over-Ethernet with the SparkFun MicroMod Ethernet Function Board. This specialized Function Board uses the W5500 Ethernet control module from WIZnet and a DC/DC converter to configure a MicroMod assembly as a connected and powered device into an Ethernet network with a Power-over-Ethernet (PoE) system.
將您的 MicroMod 專案整合到乙太網網路中，包括使用 SparkFun MicroMod 乙太網功能板的乙太網供電。該專用功能板使用WIZnet的W5500乙太網控制模組和DC/DC轉換器將 MicroMod 元件配置為具有乙太網供電 （PoE） 系統的乙太網網路中的連接和供電設備。
The W5500 Ethernet Controller from WIZnet is a TCP/IP embedded Ethernet controller that uses SPI communication protocol to allow up to eight independent sockets to operate simultaneously. The W5500 SPI interface operates at up to 80MHz and supports fast SPI for high speed Ethernet communication. The chip also includes a Wake on Lan (WOL) operation and power down mode to help conserve power.
WIZnet 的 W5500 乙太網控制器是一款 TCP/IP 嵌入式乙太網控制器，它使用 SPI 通信協定，允許多達八個獨立的插槽同時工作。W5500 SPI介面工作頻率高達80MHz，支援高速乙太網通信的快速SPI。該晶片還包括局域網喚醒 （WOL） 操作和斷電模式，以幫助節省功耗。
The board uses a Ag9900m Power-over-Ethernet (PoE) DC/DC converter module to power MicroMod assemblies from a PoE source such as a router or network switch. The DC/DC converter supplies 9 Watts @5V to connected devices. This Function Board configures the PoE supply voltage to the IEEE802.3af Alternate B power scheme. This power scheme uses the spare pairs in the Ethernet cable (4,5 and 7,8) for positive and negative DC voltage, isolating power delivery from the data lines.
該評估板使用 Ag9900m 乙太網供電 （PoE） DC/DC 轉換器模組，從 PoE 源（如路由器或網路交換機）為 MicroMod 元件供電。DC/DC 轉換器可為連接的設備提供 9 瓦@5V。該功能板為IEEE802.3af備用B電源方案配置PoE電源電壓。此電源方案使用乙太網電纜中的備用對（4、5 和 7，8）作為正負直流電壓，將電力輸送與數據線隔離開來。
With the MicroMod standardization, users no longer need to cross-reference schematics with datasheets, while fumbling around with jumper wires. Simply, match up the function board's M.2 edge connector to the slot of the M.2 connector on the main board and secure the function board with screws.
通過MicroMod標準化，使用者不再需要將原理圖與數據表交叉引用，同時摸索跳線。只需將功能板的 M.2 邊緣連接器與主機板上 M.2 連接器的插槽相匹配，然後用螺釘固定功能板即可。
Note: A MicroMod Processor, Main Board, and Ethernet accessories are not included with this MicroMod Ethernet Function Board. These parts will need to be purchased separately.
注意：MicroMod 處理器、主機板和乙太網附件不包括在此 MicroMod 乙太網功能板中。這些部件需要單獨購買。
MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!
