 # Get started with IoT Hub module identity and module twin (C)

 > [!NOTE]
-> [Module identities and module twins](iot-hub-devguide-module-twins.md) are similar to Azure IoT Hub device identity and device twin, but provide finer granularity. While Azure IoT Hub device identity and device twin enable the back-end application to configure a device and provides visibility on the device’s conditions, a module identity and module twin provide these capabilities for individual components of a device. On capable devices with multiple components, such as operating system based devices or firmware devices, it allows for isolated configuration and conditions for each component.
