Overview

The Expo SDK provides access to device and system functionality such as contacts, camera, and GPS location. It is provided by the npm package expo this is installed by default in every managed Expo project. You can import modules from it in your JavaScript code as follows:
import * as Contacts from 'expo-contacts';
import { Gyroscope } from 'expo-sensors';
This allows you to write Contacts.getContactsAsync(), for example.

Each month there is a new Expo SDK release that typically updates to the latest version of React Native and includes a variety of bugfixes, features and improvements to the Expo APIs. It's often useful to know what version of React Native your Expo project is running on, so the following table maps Expo SDK versions to their included React Native version.
