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\nThis 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.\n\nKey Features\n\n\n802.11b/g/n WiFi – WEP, WPA, and WPA2 encryption with TLS 1.2 support\n\nuFL Antenna Connector – Attach an external antenna for extended range\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\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 extended WiFi range\nSecure web client applications with TLS 1.2\nData logging to SD card from cloud services\nOutdoor or long-range wireless sensor networks\n\n\nPackage Contents\n\n1× Adafruit WINC1500 WiFi Shield with uFL Connector\n\n\n\nNote: External antenna sold separately. 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":6561,"title":"Default Title","sku":"AF-3654","price":51.22,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
