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.

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. A separate 3.3V regulator and tri-state chip on MOSI allow safe sharing of the SPI bus with other FeatherWings.

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
• Shared SPI Bus – Tri-state MOSI allows sharing with other FeatherWings
• FeatherWing Form Factor – Stacks with any Feather board

Compatibility

• Arduino – Works with Feather M0, M4, nRF52840 and similar (recommended: M0 or M4 for best results)
• CircuitPython – Requires Feather M4 or nRF52840 minimum (M0 does not have enough RAM)
• Not useful with ESP8266 or ESP32 Feathers (they already have WiFi)

Also Available

• AirLift ESP32 WiFi Breakout – Universal breakout for any microcontroller
• AirLift Bitsy Add-On – Compact version for ItsyBitsy boards
• AirLift Shield – Arduino shield version with microSD socket

Ideal For

• Adding WiFi to Feather projects
