Adding wireless connectivity to an electronics project is a great way to enhance functionality and make it stand out. Our selection of wireless electronics includes radio frequency modules, such as the Wixel, and Bluetooth modules, like the BlueSMiRF Silver from SparkFun, but until recently, we did not carry a good solution to adding Wi-Fi to a project. That’s where the newest additions to our wireless selection come into play.
We are now carrying two CC3000 Wi-Fi module carrier boards from Adafruit: the CC3000 Wi-Fi Shield for Arduino and CC3000 Wi-Fi breakout board. The CC3000 is a self-contained wireless network processor with an SPI interface, so it is not limited to a fixed UART baud rate, and the Adafruit carrier boards include level shifters, so they should be simple to connect to almost any microcontroller. Adafruit’s CC3000 Arduino library and example sketches make them especially easy to use with an Arduino-compatible board.
The CC3000 Wi-Fi Shield for Arduino offers a MicroSD card socket, a prototyping area for soldering extra circuitry, and a button for resetting the Arduino. The CC3000 Wi-Fi breakout board (v1.1) is much more compact and is also breadboard-compatible. Both products include an onboard ceramic antenna.
