This Arduino shield from Adafruit features TI’s CC3000 Wi-Fi module with an onboard ceramic antenna, a microSD card socket, and a designated prototyping area. The CC3000 uses SPI for communication instead of UART, so the communication speed is not limited to a fixed baud rate. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP, and AES, and a built-in TCP/IP stack with a BSD socket interface supports TCP and UDP in client and server mode with up to 4 concurrent socket connections. An Arduino library and example sketches make it easy to get started.
The Adafruit WiFi Shield for Arduino is based on the CC3000 Wi-Fi module from TI. The onboard ceramic antenna, microSD card socket, designated prototyping area, reset button, and the Adafruit CC3000 Arduino library allow for easy integration into an Arduino project. The CC3000 uses SPI for communication instead of UART, so the communication speed is not limited to a fixed baud rate. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP, and AES. A built-in TCP/IP stack with a BSD socket interface supports TCP and UDP in client and server mode with up to 4 concurrent socket connections. We also carry the more compact Adafruit CC3000 Wi-Fi breakout board with ceramic antenna.
Note: The CC3000 does not support “AP” mode; it can connect to an access point, but it cannot be an access point.
The CC3000 Wi-Fi shield and associated CC3000 Adafruit Arduino library are compatible with the Arduino Leonardo, Uno, and Mega. See the CC3000 WiFi Shield section of the Adafruit Shield Compatibility Guide for a full list of tested and compatible Arduino boards. (We have confirmed that the CC3000 shield and library are compatible with the Arduino Leonardo, even though as of July 2014, the Adafruit Shield Compatibility Guide says it is not compatible.) This shield is also compatible with the A-Star 32U4 Prime.
For documentation and resources to help you use the Wi-Fi shield, including tutorials, see the guide on Adafruit’s site.
The shield ships with all of its surface-mount parts populated. However, soldering is required for assembly of the included 0.1″ male headers. If you plan on stacking multiple shields, we recommend our stackable 0.1″ female header set for Arduino shields. When using the shield with an Arduino Leonardo or Mega, the included 2 × 3 female header can be used to connect to the ICSP header on the Arduino. The 2 × 3 female header is not required for use with an Arduino Uno.
Arduino and MicroSD card not included.
Note: This product is Adafruit product ID 1491.
