The Atmel® SmartConnect SAM W25 is a low-power Wi-Fi certified module.

This highly integrated module offers the ideal solution for designers seeking Wi-Fi connectivity.

The SAM W25 integrates 802.11 IP stack on top of the Wi-Fi core and fully covers RF certifications.

The SAM W25 from Atmel opens the door to the Internet of Things for a vast array of battery-powered devices and applications requiring the integration of WLAN connectivity without compromising on cost and power consumption.

The SAM W25 module is based on Atmel’s industry-leading WINC1500 Wi-Fi core combined with Atmel’s latest ARM® Cortex® -M0+ based microcontroller technology. This turnkey system provides an integrated software solution with application and security protocols such as TLS and integrated network services (TCP/IP stack).
