  • Communication Interface: SPI
  • Input Voltage Range: 36 - 57 V

The SparkFun MicroMod Ethernet Function Board - W5500 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.

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 80 MHz 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.

The board uses an 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 at 5 V 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.

Note: MicroMod Processor, Main Board, and Ethernet accessories are not included and need to be purchased separately.
