The W5500 Ethernet Shield for Arduino from Seeed Studio is a great way to set up your projects with internet connectivity with just a single chip.  Similar to the Arduino Ethernet Shield, but with a newer chipset, this ethernet shield supports both TCP and IP Protocols in TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPoE format.  The RJ45 ethernet port is also low enough so you can stack another shield on top of it The board includes...

Arduino WiFi Shield 101 is the new IoT enabler shield based on the ATWINC1500 module, developed with ATMEL, that connects your Arduino to the internet wirelessly! Connecting it to a WiFi network is simple, no further configuration in addition to the SSID and the password are required. The WiFi Shield 101 comes with an easy-to-use library that allow to connect you Arduino board to internet with few instructions. The WiFi Shield 101 also...

For years we've seen all sorts of microcontroller-friendly WiFi modules but none of them were really Adafruit-worthy. Either they were too slow, or too difficult to use, or required signing an NDA, or had limited functionality, or too expensive, or too large. So we shied away from creating or developing a WiFi Arduino shield. NO LONGER! The CC3000 hits that sweet spot of usability, price and capability. It uses SPI for communication (not...

The Arduino Ethernet Shield R3 (assembled) allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip (datasheet). 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. Adafruit started shipping the R3 version on Feb. 3, 2012 at 3:30pm ET....
