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.

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 for data storage or hosting. This version features a built-in PCB antenna. Works best with SAMD21-based boards like the Metro M0 Express or Arduino Zero; also compatible with Arduino Mega.
