{"title":"Adafruit AirLift FeatherWing – ESP32 WiFi Co-Processor","handle":"adafruit-airlift-featherwing-esp32-wifi-co-processor","url":"/products/adafruit-airlift-featherwing-esp32-wifi-co-processor","description":"Give your Feather project WiFi connectivity with the Adafruit AirLift FeatherWing. This add-on uses an ESP32 as a WiFi co-processor, handling all the heavy lifting of network connections and TLS/SSL encryption so your main Feather can focus on your application logic.\n\nThe ESP32 communicates over 8 MHz SPI for high-speed data transfer, requiring just an SPI bus and 2 control pins. It comes pre-programmed with WiFi co-processor firmware (a variant of Arduino WiFiNINA) and has root certificates pre-burned in for secure HTTPS connections. A separate 3.3V regulator and tri-state chip on MOSI allow safe sharing of the SPI bus with other FeatherWings.\n\nKey Features\n\n\nESP32 WiFi Co-Processor – Handles WiFi networking and TLS/SSL encryption\n\n8 MHz SPI Interface – High-speed communication with just SPI + 2 control pins\n\nPre-Programmed Firmware – Ready to use out of the box with Arduino and CircuitPython\n\nTLS/SSL Support – Root certificates pre-burned for secure connections\n\nShared SPI Bus – Tri-state MOSI allows sharing with other FeatherWings\n\nFeatherWing Form Factor – Stacks with any Feather board\n\n\nCompatibility\n\n\nArduino – Works with Feather M0, M4, nRF52840 and similar (recommended: M0 or M4 for best results)\n\nCircuitPython – Requires Feather M4 or nRF52840 minimum (M0 does not have enough RAM)\n\nNot useful with ESP8266 or ESP32 Feathers (they already have WiFi)\n\n\nAlso Available\n\n\nAirLift ESP32 WiFi Breakout – Universal breakout for any microcontroller\n\nAirLift Bitsy Add-On – Compact version for ItsyBitsy boards\n\nAirLift Shield – Arduino shield version with microSD socket\n\n\nIdeal For\n\nAdding WiFi to Feather projects\nIoT data logging and cloud connectivity\nWeb API integrations\nSecure HTTPS communication\n\n\nPackage Contents\n\n1× Adafruit AirLift FeatherWing (assembled and tested)\n1× Header strip\n\n\n\nNote: Feather board not included. Enterprise WiFi is not supported. Power supply must provide up to 250 mA during WiFi usage. Some light soldering required to attach the included headers.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5188,"title":"Default Title","sku":"AF-4264","price":26.46,"on_sale":false,"in_stock":true,"available_quantity":46,"option1":"Default Title"}]}
