The ENC28J60 Ethernet Module utilizes the new Microchip ENC28J60 Stand-Alone Ethernet Controller IC featuring a host of features to handle most of the network protocol requirements. The board connects directly to most microcontrollers with a standard SPI interface with a transfer speed of up to 20MHz.

• Small breakout board for the PIC Microchip ENC28J60. It contains all the necessary hardware to implement an Ethernet interface including the isolation transformer and LINK/STATUS LEDs.
• Support 3.3V and 5V Power supply, need you to choose 3.3V and 5V by the switch.
• 1×10 connector can be easily mounted with the MCU
• SPI Interface

• Based on the w5100based on the wiznet w5100 allows an Arduino board to connect to the internet.
• Stackable design can directly be supported by the Arduino official ethernet library.
• Supports up to four simultaneous socket connections
• It can use to store files for serving over the network.
• Compatible with the for Arduino (168 or 328), uno as well as mega (1280/2560).
• It can be accessed using the mini SD tf library.
• Operating voltage:5v.
• Ethernet controller: w5100 with an internal 16k buffer.
• Connection speed: 10/100mb.
• Package content: 1 x ethernet shield w5100 development board or for Arduino UNO mega 2560 1280 328 uno.

Features:

• ETHERNET SHIELD WIZNET W5100 FOR ARDUINO UNO MEGA 1280 2560 MICRO SD CARD
• This Ethernet Shield which is based on the Wiznet W5100 Ethernet Chip gives you an easy way to get your for Arduino Online. It is directly supported by For Arduino official Ethernet Library. It adds a micro-SD card slot, which can be used to store files for serving over the network
• It is compatible with for Arduino Duemilanove (168 or 328), Uno as well as Mega (1280/2560) and can be accessed using the SD library. The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP
• It supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.

W5500 Ethernet Network Module TCP/IP SPI Interface 51/STM32 Program W5100 Upgrade Edition. The W5500 module is a module based on Ethernet WIZNET new type of chip W5500, module integrates the whole hardware TCP/IP protocol stack, no need code implements the TCP/IP protocol stack, support transmission rate of 10/100MBPS, support sleep mode and wake on LAN, Within the integrated 32K TX/RX cache, support 8 independent ports run at the same time, Module supports 3.3V or 5V power supply, convenient for the user to use in the SCM system different, module and MCU system communication mode is SPI protocol, Support SPI clock frequencies up to 80M, provide STM32 and 51 SCM client, server, three modes of UDP routines.

• Requires an Arduino board (not included)
• Operating voltage 5V (supplied from the Arduino Board)
• SPI (Serial Peripheral Interface) provides an easy interface connected to the external MCU.
• The W5500 supports up to 80MHZ SPI communication speed.
• In order to reduce system power consumption, W5500 provides a network wake-up and sleep modes. W5500 will wake when receiving the original Ethernet packet in the form of the magic packet
