# Amazon IoT Device SDKs, Mobile SDKs, and Amazon IoT Device Client This page summarizes the Amazon IoT Device SDKs, open-source libraries, developer guides, sample apps, and porting guides to help you build innovative IoT solutions with Amazon 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 [Amazon Mobile SDKs](#iot-mobile-sdks). If you're developing an IoT app or server-side program, see the [Amazon SDKs](iot-connect-service.md#iot-service-sdks). ## Amazon IoT Device SDKs The Amazon 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 Amazon IoT Device SDKs have released an MQTT 5 client. The Amazon IoT Device SDKs don't support using TLS 1.3 on macOS. These SDKs help you connect your IoT devices to Amazon IoT using the MQTT and WSS protocols. ------ #### [ C\+\+ ] **Amazon IoT C\+\+ Device SDK** The Amazon IoT C\+\+ Device SDK allows developers to build connected applications using Amazon and the Amazon IoT APIs.
