This 802.11bgn-capable module is the best new thing for networking your devices, with SSL support and rock solid performance.
Makers wishing to connect their Arduino Zero (or Uno) to the Internet can now do so with Adafruit’s new ATWINC1500 Wi-Fi Breakout Board.
The ATWINC1500 found at its core is the ideal add-on to existing MCU solutions bringing wireless and network capabilities through UART or SPI-to-Wi-Fi interface. The Wi-Fi module features a fully-integrated power amplifier, LNA, switch and power management, as well as internal Flash memory.
“This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with SSL support and rock solid performance — running our Adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it),” Adafruit explains. “We like these so much, they’ve completely replaced the CC3000 module on all our projects.”
The Adafruit ATWINC1500 Wi-Fi Breakout uses SPI to communicate, and supports a range of security protocols including WEP, WPA and WPA2, TLS and SSL encryption.
“Right now the Atmel-supplied library works great with Arduino Zero, and seems to work OK on Uno but may not work on other Arduinos. You can clock it as fast as 12MHz for speedy, reliable packet streaming. And scanning/connecting to networks is very fast, a few seconds,” Adafruit adds.
Since this is the Adafruit crew’s new favorite SPI-protocol Wi-Fi module, and rightfully so, they’ve gone ahead and created a little breakout for it. This 1.3″ x 1.1″ x 0.16” board comes with level shifting on all the input pins so you can use it with 3V or 5V logic, a 3.3V voltage regulator, and a trio of LEDs that can be controlled either over the SPI interface (part of the library code) or by the Arduino library. They’ll light up when hooked up to an SSID, or transmitting data.
