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.\n\nThe 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.\n\nKey Features\n\n\n802.11b/g/n WiFi – WEP, WPA, and WPA2 encryption with TLS 1.2 support\n\nSPI Communication – Up to 12 MHz clock speed for fast, reliable data streaming\n\nSoft AP Mode – Create ad-hoc networks for direct device connections\n\nBuilt-in PCB Antenna – No external antenna required\n\n3V & 5V Compatible – Onboard level shifting and 3.3V regulator (handles 300 mA spikes)\n\nMicroSD Card Socket – Store or host data (requires SAMD21-based board for simultaneous WiFi + SD use)\n\n3× Status LEDs – Controllable via SPI or Arduino library for connection and data indicators\n\n\nIdeal For\n\nIoT projects requiring WiFi connectivity\nSecure web client applications with TLS 1.2\nData logging to SD card from cloud services\nWireless sensor networks and home automation\n\n\nPackage Contents\n\n1× Adafruit WINC1500 WiFi Shield with PCB Antenna\n\n\n\nNote: ATmega328-based boards (like Arduino UNO) can use this shield but have limited memory — simultaneous WiFi and SD card use is not possible. For best results, use a SAMD21-based board such as the Metro M0 Express.\n\n\nResources\n\nAdafruit Learn Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6559,"title":"Default Title","sku":"AF-3653","price":48.68,"on_sale":false,"in_stock":true,"available_quantity":33,"option1":"Default Title"}]}
