1 Overview
This document defines the Application Programming Interface (API) that all AWS IoT ExpressLink compliant connectivity modules are required to implement to connect any host processor to the AWS cloud.
ExpressLink modules were conceived after discussions with microcontroller vendors, OEMs, and module makers. These modules reduce the complexity and repetitiveness of connecting existing and new hardware and software designs to new or different MCUs and RTOSs. This allows a scalable migration for millions of embedded applications to cloud-connected applications.
