# AWS IoT Device SDKs, Mobile SDKs, and AWS IoT Device Client This page summarizes the AWS IoT Device SDKs, open-source libraries, developer guides, sample apps, and porting guides to help you build innovative IoT solutions with AWS IoT and your choice of hardware platforms. These SDKs are for use on your IoT device. If you're developing an IoT app for use on a mobile device, see the [AWS Mobile SDKs](#iot-mobile-sdks). If you're developing an IoT app or server-side program, see the [AWS SDKs](iot-connect-service.md#iot-service-sdks). ## AWS IoT Device SDKs The AWS IoT Device SDKs include open-source libraries, developer guides with samples, and porting guides so that you can build innovative IoT products or solutions on your choice of hardware platforms. **Note** The AWS IoT Device SDKs have released an MQTT 5 client. The AWS IoT Device SDKs don't support using TLS 1.3 on macOS. These SDKs help you connect your IoT devices to AWS IoT using the MQTT and WSS protocols. ------ #### [ C\$1\$1 ] **AWS IoT C\$1\$1 Device SDK** The AWS IoT C\$1\$1 Device SDK allows developers to build connected applications using AWS and the AWS IoT APIs.
