Adafruit HUZZAH CC3000 WiFi Breakout with Onboard Antenna

This compact WiFi module is a game changer for microcontroller enthusiasts. The CC3000 achieves the perfect blend of usability, performance, and affordability. It utilizes SPI communication, allowing seamless data transfer speeds while maintaining a reliable interrupt system through its IRQ pin for asynchronous connections.

The CC3000 supports 802.11b/g and secure network protocols such as WEP, WPA, and WPA2. A built-in TCP/IP stack with "BSD socket" interface handles up to 4 concurrent sockets in both client and server mode, providing robust networking capabilities.

Equipped with an onboard 3.3V regulator and tri-state buffer, it expertly manages power requirements and facilitates compatibility with 3V or 5V logic levels. Its FCC-compliant antenna design ensures optimal wireless range, comparable to modern smartphones, delivering stable connectivity.

Each package includes a fully assembled and tested breakout board alongside plug-ready headers for swift breadboard integration. Though a detailed tutorial is forthcoming, available resources include a comprehensive Arduino library with example code for tasks like SSID scanning, DHCP connection, and DNS lookups. While certain functions remain in development, users will find ample opportunities to harness the module's current capabilities.
