## 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. The 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. Key Features ESP32 WiFi Co-Processor – Handles WiFi networking and TLS/SSL encryption 8 MHz SPI Interface – High-speed communication with just SPI + 2 control pins Pre-Programmed Firmware – Ready to use out of the box with Arduino and CircuitPython TLS/SSL Support – Root certificates pre-burned for secure connections 3V and 5V Compatible – On-board 3.3V regulator and level shifting circuitry Shared SPI Bus – Tri-state MOSI allows sharing with other SPI devices Breadboard-Friendly – Includes header strip for solderless breadboard use Compatibility Arduino – Works with ATmega328 and up, though larger chips (SAMD51, etc.) recommended for complex tasks CircuitPython – Requires SAMD51/Cortex M4 minimum for sufficient RAM Also Available AirLift Bitsy Add-On – Compact version designed to stack on ItsyBitsy boards Ideal For Adding WiFi to existing microcontroller projects IoT data logging and cloud connectivity Web API integrations Secure HTTPS communication Package Contents 1× Adafruit AirLift ESP32 WiFi Co-Processor Breakout (assembled and tested) 1× Header strip Note: 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.
