Produktbeschreibung

Das CC3000 WiFi Breakout basiert auf Texas Instruments CC3000 WiFi Modul, welches ein kostengünstigen Einstieg in die drahtlose WLan Welt ermöglicht.
Auf dem Breakout befinden sich die Spannungsversorgung ein ein Pegelwandler, der den Betrieb auch an 5V Mikrocontrollern ermöglicht.
Der komplette TCP/IP Stack ist in dem CC3000 integriert.


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! As we try to complete the functionality, check or subscribe to the github repo for instant updates. For now we suggest this module and codebase for people with some programming and microcontroller experience

For use with Arduino Uno & Mega only at this time - we'll try to get the code ported to the Leonardo/Due at some point but no ETA. To wire it up: Connect Vin to 5V and Ground to common ground. SCLK connects to your Arduino's hardware SPI Clock pin, MOSI to the SPI MOSI pin, MISO to the SPI MISO pin, CS to digital #10, VBEN to digital #5, and IRQ to digital #3
