Adafruit ATWINC1500 WiFi Breakout

Connect your Arduino to the Internet seamlessly with the new FCC-certified WiFi module from Atmel. This 802.11bgn-capable WiFi module stands out for networking your devices, offering SSL support and exceptional performance, as demonstrated by its continuous operation running our adafruit.io MQTT demo for an entire weekend without interruptions.

The Adafruit ATWINC1500 WiFi Breakout utilizes SPI communication, requiring only about 6 wires to get connected swiftly. Currently, the Atmel-supplied library functions effectively with Arduino M0's and M4s; however, it's not compatible with Uno (328P) and potentially other Arduinos.

Benefits include robust packet streaming up to 12MHz and quick network scanning and connection in just seconds. The module supports 802.11b, g, or n networks and WEP, WPA, and WPA2 encryption. Create an ad-hoc network using its Soft AP mode and enjoy secure client connections with TLS 1.2 support in firmware 19.4.4.

The breakout board accommodates 3V or 5V logic with level shifting on all input pins and a 3.3V voltage regulator that handles 300mA spikes, supporting power from 3-5.5VDC. Control the 3 on-board LEDs over the SPI interface or through the Arduino library, which indicate SSID connection and data transmission.

Included are a solderable header for breadboard integration and a comprehensive set of tutorials and code for easy implementation. Enhance your projects with this reliable and versatile WiFi module, the new standard for SPI-protocol WiFi connectivity.
