Your Entry to the WIZnet Connect the Magic 2014 Design Challenge must use at least one WIZnet WIZ550io or W5500 chip. Visit WIZnet’s product page for more information about the WIZ550io.
The WIZ550io is an auto-configurable Ethernet controller module that includes the W5500 (TCP/IP-hard-wired chip and PHY embedded), transformer, and an RJ-45 connector. The module has a unique, embedded real MAC address and auto network configuration capability.
When powered on, the WIZ550io initializes itself with the MAC and default IP address and can be pinged from your computer. Thus, you don’t need to write MAC and network information such as an IP address, subnet mask, and gateway address.
