Adafruit AirLift – ESP32 WiFi Co-Processor Breakout Board

Key Features ESP32 module on a PCB with level shifting circuitry A tri-state chip for MOSI so you can share the SPI bus with other devices Send basic but powerful socket-based commands over 8MHz SPI for high speed data transfer Works great with CircuitPython, a SAMD51/Cortex M4 minimum required since we need a bunch of RAM Fully assembled and tested, pre-programmed with ESP32 SPI WiFi co-processor firmware Give your plain ol' microcontroller project a lift with the Adafruit AirLift - a breakout board that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite microcontroller (like the ATmega328 or ATSAMD51), awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if its using the latest TLS/SSL encryption (it has root certificates pre-burned in).Having WiFi managed by a
