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...

Connect your Arduino-compatible to the Internet with this WiFi shield that features the FCC-certified ATWINC1500 module from Atmel. This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with SSL support and rock solid performance - running our adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it). The Adafruit ATWINC1500 WiFi...

Give your Arduino project a lift with the Adafruit AirLift Shield - a shield that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite Arduino-compatible (like the Metro M4 or the classic Metro 328) that comes with its own set of awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of...

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....

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...

Arduino has discontinued this shield, please check out the Adafruit WINC1500 shield for a nearly-identical replacement with the same exact module, and the addition of a micro SD card holder and prototyping area. 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...
