Adafruit AirLift – ESP32 WiFi Co-Processor Breakout Board

Boost your microcontroller project with the Adafruit AirLift, a breakout board that utilizes the powerful ESP32 as a WiFi co-processor. Perfect for enhancing your favorite microcontroller, it seamlessly integrates with devices like the ATmega328 or ATSAMD51, offering a WiFi solution without complexity.

Experience effortless connection with built-in TLS/SSL encryption and pre-burned root certificates. The ESP32 manages WiFi tasks, simplifying your code by eliminating the need to compile SSL libraries or handle socket data caches.

Transfer data swiftly at 8MHz over SPI with sockets, compatible with 3V or 5V Arduino setups. The board works exceptionally well with CircuitPython, especially with a SAMD51/Cortex M4, requiring minimal RAM.

Designed with level shifting circuitry, a 3.3V regulator, and a tri-state chip, share the SPI bus easily. Operating requires simply an SPI bus and two control pins, along with a power supply of up to 250mA during WiFi usage.

Supplied fully assembled with pre-programmed ESP32 SPI WiFi co-processor firmware, enable seamless integration in CircuitPython. Includes additional header for easy soldering onto a breadboard. Note that Enterprise WiFi connection is not yet supported.
