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 Adafruit 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 UART!) so you can push data as fast as you want or as slow as you want. It has a proper interrupt system with IRQ pin so you can have asynchronous connections. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP & AES. A built in TCP/IP stack with a "BSD socket" interface. TCP and UDP in both client and server mode, up to 4 concurrent sockets. It does not support "AP" mode, it can connect to an access point but it cannot be an access point.

Please note that the CC3000 module is being phased out and we suggest the WINC1500 as a replacement - it has SSL support, soft-AP capability, and is more reliable.

Adafruit carefully wrapped this little silver module into an Arduino shield. They also added a microSD socket and a reset button. It has an onboard 3.3V regulator that can handle the 350mA peak current, and a level shifter to allow 3 or 5V logic level. The antenna layout is identical to TI's suggested layout and Adafruit are using the same components, trace arrangement, and antenna so the board maintains its FCC emitter compliance (you'll still need to perform FCC validation for a finished product, but the WiFi part is taken care of). Even though it's got an onboard antenna Adafruit were pretty surprised at the range, as good as a smartphone's.

Each order comes with one fully assembled and tested shield, some male header for attaching it to an Arduino and a 2x3 female header that you can use to plug it into the ICSP port of a Mega. Adafruit don't have a detailed tutorial yet but to get you started, Adafruit have got a fully working Arduino library that is based off of TI's codebase but adapted for use with the AVR. We also have example code showing how to scan the SSID's, connect to your access point and run DHCP, do a DNS lookup to IP address, ping a site and connect to a remote TCP socket such as a website and print out the page.

Please note the hardware is good, but the library code does not yet support all of the CC3000's functionality. At this moment, SSID scanning, connection, DHCP, DNS lookup, ping, and UDP/TCP client & TCP server connections (eg connect to a website and grab data or host a very short website) all work and are tested with example code. Check out Adafruit's tutorial for wiring and Arduino library downloads

For use with Arduino Uno, Mega, Leonardo/Micro only at this time - we'll try to get the code ported to the Due at some point but no ETA.

    This worked exactly as I needed.
    As a first time soldering project just to get it working it was easy to understand and follow.
    Online materials and guides were more than adequate. (Posted on 19/03/2014)

  2. Review by Phil - Great product, easy WiFi connection.

    Another great product from Adafruit. Comprehensive website related to the shield with great examples that can with a little effort be re-tasked to suit your needs. (Posted on 9/12/2013)
