Adafruit CC3000 WiFi Shield with uFL Connector for Ext Antenna

The CC3000 module marks a new era in WiFi communication for microcontrollers. Experience seamless data transfer using SPI communication, bypassing the usual bottlenecks of UART. With its robust interrupt system, asynchronous connections are now easily attainable. Enjoy compatibility with 802.11b/g and support for secure protocols, including WEP, WPA/WPA2, TKIP, and AES.

Leverage the built-in TCP/IP stack offering a 'BSD socket' interface, with capabilities for TCP and UDP in both client and server modes, handling up to four concurrent sockets. While it cannot function as an access point, it excels in connecting to existing networks. For an even more advanced alternative, consider WINC1500, which adds SSL support and soft-AP capability.

This Arduino shield, featuring a CC3000 module, incorporates an onboard 3.3V regulator capable of handling a 350mA peak current and supports both 3V and 5V logic levels thanks to its level shifter. The absence of an onboard antenna is accounted for with a uFL connector, permitting use of an external 2.4GHz antenna for extended range and versatile enclosures.

Included are an assembled and tested shield, male headers, and a 2x3 female header for easy integration with an Arduino Uno or Mega. Though a detailed tutorial is pending, a working Arduino library and example code are available for immediate use, covering SSID scanning, connection setup, DHCP, DNS, ping, and remote TCP socket connections.
