Adafruit CC3000 WiFi Breakout with Onboard Ceramic Antenna

Product details

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 we shied
away from carrying any general purpose microcontroller-friendly WiFi
boards.

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.

We wrapped this little silver modules in a tidy breakout board. 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 we're 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 we were pretty surprised at the
range, as good as a smartphone's.

Each order comes with one fully assembled and tested breakout and a
small stick of header you can use to solder in and plug into a
breadboard. We don't have a detailed tutorial yet but to get you
started, we've 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. SSID scanning, connection,
DHCP, DNS lookup, ping, and UDP/TCP client connections (eg connect to
a website and grab data) all work and are tested with example code.
UDP/TCP server connections are not supported yet! Check out our
tutorial for wiring and Arduino library downloads [1]

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