{"title":"Adafruit AirLift – ESP32 WiFi Co-Processor Breakout Board","handle":"adafruit-airlift-esp32-wifi-co-processor-breakout-board","url":"/products/adafruit-airlift-esp32-wifi-co-processor-breakout-board","description":"Give any microcontroller WiFi connectivity with the Adafruit AirLift Breakout. This board uses an ESP32 as a WiFi co-processor, handling all the heavy lifting of network connections and TLS/SSL encryption so your main microcontroller 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. On-board level shifting and a 3.3V regulator let you use it with both 3V and 5V microcontrollers.\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\n3V and 5V Compatible – On-board 3.3V regulator and level shifting circuitry\n\nShared SPI Bus – Tri-state MOSI allows sharing with other SPI devices\n\nBreadboard-Friendly – Includes header strip for solderless breadboard use\n\n\nCompatibility\n\n\nArduino – Works with ATmega328 and up, though larger chips (SAMD51, etc.) recommended for complex tasks\n\nCircuitPython – Requires SAMD51/Cortex M4 minimum for sufficient RAM\n\n\nAlso Available\n\n\nAirLift Bitsy Add-On – Compact version designed to stack on ItsyBitsy boards\n\n\nIdeal For\n\nAdding WiFi to existing microcontroller projects\nIoT data logging and cloud connectivity\nWeb API integrations\nSecure HTTPS communication\n\n\nPackage Contents\n\n1× Adafruit AirLift ESP32 WiFi Co-Processor Breakout (assembled and tested)\n1× Header strip\n\n\n\nNote: Enterprise WiFi is not supported. Power supply must provide up to 250 mA during WiFi usage. Some light soldering is required to attach the included header pins.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5311,"title":"Default Title","sku":"AF-4201","price":20.34,"on_sale":false,"in_stock":true,"available_quantity":37,"option1":"Default Title"}]}
