The Smallest Network Module Board For AVR PIC ARM MCU ENC28J60 is Microchip Technology (Microchip Technology, Inc.) recently introduced a 28-pin independent Ethernet controllers.
Small size breakout
With LINK/STATUS and Power LEDs
Seeeduino Ethernet is a compact and multifunctional development platform, which merges data logging and processing, device control and Ethernet communication together into one. It's armed with a MEGA328P chip and a Wiz5100: the former provides an Arduino controlling style and the latter provides TCP and UDP Ethernet communication ability.
The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip. 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. The...
It's a breakout board for W5100 embedded TCP/IP chip. Included on the board is an RJ-45 with X’FMR connector. It can be used as a component and little effort is required to interface to the W5100. This module is an ideal option for users who want a simple solution to adding TCP/IP capability to their project.
It's a small breakout board for the ENC28J60 Ethernet chip. Contains all the necessary hardware to implement an Ethernet interface including the isolation transformer and LINK/STATUS and power LEDs. SPI interface makes this one of the easiest 10Base-T ICs yet. It's 3.3V with 8KB buffer.
