It's easy to use the Adafruit AirLift breakout with CircuitPython and the Adafruit CircuitPython

ESP32SPI (https://adafru.it/DWV) module. This module allows you to easily add WiFi to your project.

CircuitPython Microcontroller Wiring

First, wire up your AirLift as follows. The following example shows it wired to a Feather M4 using SPI:

Board VIN to Feather USB

Board GND to Feather GND

Board SCK to Feather SCK

Board MISO to Feather MI

Board MOSI to Feather MO

Board CS to Feather D10

Board BUSY to Feather D9

Board !RST to Feather D6

You must use USB or VBAT for powering the AirLift

Breakout!

CircuitPython Installation of ESP32SPI Library

You'll need to install the Adafruit CircuitPython ESP32SPI (https://adafru.it/DWV) library on your CircuitPython board.

First make sure you are running the latest version of Adafruit CircuitPython (https://adafru.it/Amd) for your board.

Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these

libraries from Adafruit's CircuitPython library bundle (https://adafru.it/uap). Our CircuitPython starter guide has a great

page on how to install the library bundle (https://adafru.it/ABU).

You can manually install the necessary libraries from the bundle:

adafruit_esp32spi.mpy

adafruit_requests.mpy

adafruit_bus_device

Before continuing make sure your board's lib folder or root filesystem has the adafruit_esp32spi.mpy, and

adafruit_bus_device files and folders copied over.

Next connect to the board's serial REPL (https://adafru.it/Awz) so you are at the CircuitPython >>> prompt.

CircuitPython Usage

The ESP32SPI library requires an M4 or better microcontroller! The M0 will not work.
