The Adafruit ATWINC1500 WiFi Breakout adds fast, reliable 802.11b/g/n connectivity with SSL support to your Arduino - ideal for IoT projects needing secure, high-performance wireless networking.
Connect your Arduino to the Internet with this fine new FCC-certified WiFi module from Atmel. 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). We like these so much, they've completely replaced the CC3000 module on all our projects.
The Adafruit ATWINC1500 WiFi Breakout uses SPI to communicate, so with about 6 wires, you can get your wired up and ready to go. Right now the Atmel-supplied library works great with Arduino M0's and M4s but does not work on Uno (328P) and 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.
This module works with 802.11b, g, or n networks & supports WEP, WPA and WPA2 encryption. You can use it in Soft AP mode to create an ad-hoc network. For secure client connections, there is TLS 1.2 support in firmware 19.4.4!
Since this is our new favourite SPI-protocol WiFi module we've decided to make a little breakout for it. The breakout comes with level shifting on all the input pins so you can use it with 3V or 5V logic. A 3.3V voltage regulator that can handle the 300mA spikes lets you power from 3-5.5VDC. There's also 3 LEDs that you can control over the SPI interface (part of the library code) or you can have controlled by the Arduino library. They'll light up when connected to an SSID, or transmitting data.

Revision History
As of October 27, 2023 - we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
