Red Board W5100 Ethernet Module

Introduction:

The W5100 is a versatile single-chip network interface chip with an integrated 10/100 Ethernet controller for use in highly integrated, highly stable, high-performance and low-cost embedded systems. Use the W5100 to implement an Internet connection without an operating system . The W5100 is compatible with IEEE802.3 10BASE-T and 802.3u 100BASE-TX . The W5100 integrates the entire hardware, and after years of market-proven TCP / IP stack, Ethernet media transport layer ( MAC ) and physical layer ( PHY ). The use of W5100 does not need to consider the control of Ethernet, only need a simple port ( Socket ) programming.
