The Avalanche Board supports several standard interfaces, including:



Microsemi VSC8531 with an RJ45 connector for 10/100/1000 Mbps Ethernet



One full-duplex transceiver lane connected through SFP+ connector



DDR3 memory



2.4 GHz ISM band using Panasonic PAN9320 Wi-Fi module



Arduino™ compatible expansion headers



MikroBUS™ compatible expansion headers



PMOD™ compatible expansion connector



One SPI flash device

The following illustration highlights various components of the Avalanche Board.
