Project Description



W5100 Ethernet shield V1.1 is a WIZnet W5100 breakout board with POE and Micro-SD designed for Arduino platform. 5V/3.3V compatible operation voltage level makes it compatible with Arduino boards, leafmaple, and other Arduino compatible boards except Mega boards.

Note: the POE of W5100 shield is dummy POE. Because in the 100M ethernet wire, 7/8 pins are not used. It will be connected to VIN pin of arduino board directly.



  • With Micro SD socket
  • 5V/3.3V double operational voltage level
  • 10Mb/100Mb Ethernet socket with POE
  • All electronic brick interface are broken out
