Adafruit HUZZAH CC3000 WiFi Breakout with Onboard Antenna [v1.1]

The Adafruit HUZZAH CC3000 WiFi Breakout adds 802.11b/g WiFi connectivity to your Arduino projects via SPI. Built around the TI CC3000 module with a built-in TCP/IP stack, it supports open, WEP, WPA, and WPA2 security with TKIP and AES encryption. The on-board antenna delivers range comparable to a smartphone, and the breakout includes a 3.3V regulator and level shifting for 3V or 5V logic compatibility.

Version 1.1 adds a tri-state buffer on the MISO pin, allowing the CC3000 to share an SPI bus with other devices. The module supports TCP and UDP in both client and server mode with up to 4 concurrent sockets, using a BSD-style socket interface.

Key Features

  • 802.11b/g WiFi – Open, WEP, WPA, and WPA2 security with TKIP and AES
  • SPI Interface – Fast, flexible communication with IRQ pin for asynchronous connections
  • Built-in TCP/IP Stack – BSD socket interface with TCP and UDP client/server support
  • Up to 4 Concurrent Sockets – Handle multiple connections simultaneously
  • On-Board Antenna – FCC-compliant layout with smartphone-comparable range
  • 3.3V Regulator – Handles 350 mA peak current draw
  • Level Shifting – Compatible with 3V and 5V logic levels
  • Tri-State MISO Buffer (v1.1) – Share the SPI bus with other devices
  • DHCP, DNS, and Ping Support – Built-in networking essentials

Ideal For

  • Adding WiFi connectivity to Arduino projects
  • IoT sensor nodes and data logging to web services
  • Simple web server hosting from a microcontroller
  • Remote monitoring and control projects

Package Contents

  • 1× Adafruit HUZZAH CC3000 WiFi Breakout v1.1 – Fully assembled and tested
  • 1× Header strip (unsoldered)
Note: The CC3000 does not support Access Point (AP) mode — it can connect to an existing access point but cannot act as one. Compatible with Arduino Uno, Leonardo/Micro, and Mega. Light soldering is required to attach the included header strip.
