Adafruit WINC1500 WiFi Shield with PCB Antenna

Connect your Arduino-compatible device to the Internet with the Adafruit WINC1500 WiFi Shield featuring the FCC-certified ATWINC1500 module from Atmel. This shield supports 802.11bgn WiFi with SSL and TLS 1.2 security, ensuring reliable wireless communication for your projects.

The shield communicates via SPI protocol and includes GPIO control pins, enabling easy integration with about six wires. It is compatible with SAMD21-based boards such as the Arduino Zero and Metro M0 Express, and also works with the Arduino Mega. This shield is not compatible with 328P, 32u4-based, or attiny-based boards. It operates up to 12MHz SPI clock speed for quick and reliable data streaming.

Features include WEP, WPA, WPA2 encryption, and Soft AP mode to create ad-hoc networks. It has an integrated PCB antenna and includes level shifting on input pins for 3V or 5V logic boards. A 3.3V regulator supports power from 3-5.5VDC with 300mA current spikes. The shield incorporates three controllable LEDs indicating connection status and data transmission.

Additionally, there is a micro SD card socket for local data storage or hosting. Note that Arduino devices based on the ATmega328 (e.g., UNO) cannot use both WiFi and SD simultaneously due to limited memory.

Note: No CircuitPython or MicroPython drivers are available or planned for this shield. For detailed tutorials, code, and schematics, visit the Adafruit Learning System page.
