Add WiFi connectivity to your Arduino-compatible board with the Adafruit WINC1500 WiFi Shield, featuring the FCC-certified ATWINC1500 module from Atmel. This 802.11b/g/n shield supports WEP, WPA, and WPA2 encryption with TLS 1.2 for secure connections, and communicates over SPI at speeds up to 12 MHz.

This version includes a uFL connector for attaching an external antenna, giving you extended range for projects that need it. The shield includes onboard level shifting for 3V or 5V logic boards, a 3.3V regulator rated for 300 mA spikes, three user-controllable LEDs, and a microSD card socket. Works best with SAMD21-based boards like the Metro M0 Express or Arduino Zero; also compatible with Arduino Mega. For a simpler setup without an external antenna, see the PCB antenna version.
