The 802.11bgn module is the best new device for connecting user equipment to the internet, supporting SSL and featuring robust performance. Makers looking to connect their Arduino Zero (or Uno) to the internet can now achieve this with Adafruit’s new ATWINC1500 wireless breakout board.
The ATWINC1500 at the core of the breakout board is an ideal companion device for existing microcontroller solutions that provide wireless and networking capabilities via UART or SPI-to-Wi-Fi interfaces. This wireless module is equipped with a full suite of power amplifiers, low-noise amplifiers, switches, and power management, as well as built-in flash memory. “This 802.11bgn wireless module is the best new device for connecting user equipment to the internet, supporting SSL and featuring robust performance—it can run the Adafruit.io MQTT demo all weekend without any failures (it could have run longer, but we had to unplug it because we had to go to work),” Adafruit explained. “We really love these modules; they have completely replaced the CC3000 modules in all our projects.”
Adafruit’s ATWINC1500 wireless breakout board communicates via SPI and supports a range of security protocols, including WEP, WPA, WPA2, TLS, and SSL encryption. “Currently, the library provided by Atmel runs very successfully on Arduino Zero, and it seems to work on UNO as well, but it may not run on other Arduinos. You can time it at speeds of up to 12 MHz for fast, reliable packet flow, and searching/connecting to networks is also very quick, taking only a few seconds,” Adafruit added.
As this is the latest SPI-based wireless module favored by Adafruit staff, it has rightfully earned its place. The 1.3″x1.1″x0.16″ circuit board features level shifting on all input pins, allowing users to equip it with 3V or 5V logic, a 3.3V voltage regulator, and three LEDs that can be controlled via the SPI interface (part of the library code) or by the Arduino library. The LEDs light up when connected to an SSID or when data is being transmitted. Interested? Head over to the Adafruit official website, and for just $24.95, you can have your own breakout board today!
