+
+    \title Connecting MCUs
+
+    \l{Qt for MCUs} enables you to use subsets of QML and Qt Quick Controls
+    to create user interfaces for devices that are powered by microcontroller
+    units (MCU). It includes a new graphics rendering engine that has a low
+    memory footprint and is optimized for MCUs and other resource-constrained
+    devices.
+
+    You can connect MCU boards to a development host to build applications for
+    them using the GNU Arm Embedded GCC compiler, libraries, and other GNU tools
+    necessary for bare metal software development on devices based on the Arm
+    Cortex-M processors. You can deploy the applications on MCUs to run and
+    debug them using \QC.
+
+    The toolchains are available for cross-compilation on Microsoft Windows,
+    Linux, and macOS.
+
+    The following MCU boards are currently supported:
+
+    \list
+        \li \l{https://www.st.com/en/evaluation-tools/stm32f7508-dk.html}
+            {STM32F7508-DK}
+        \li \l{https://www.st.com/en/evaluation-tools/32f769idiscovery.html}
+            {32F769IDISCOVERY}
+        \li \l{https://www.nxp.com/design/development-boards/i.mx-evaluation-and-development-boards/i.mx-rt1050-evaluation-kit:MIMXRT1050-EVK}
+            {NXP i.MX RT1050 EVK}
+    \endlist
+
+    For a list of Qt for MCU reference implementations, see the Qt for MCU
+    documentation.
+
+    You use the \l{Connecting Bare Metal Devices}{Bare metal plugin} to connect
+    to OpenOCD or ST-LINK Utility for debugging on MCUs.
+
+    \section1 Requirements
+
+    To use \QC to develop QML applications for MCUs, you need the following:
+
+    \list
+        \li Qt for MCU SDK
+        \li The Bare Metal plugin
+        \li GNU ARM Embedded Toolchain
+        \li For STM32 boards:
+        \list
+            \li \l{https://www.st.com/en/embedded-software/stm32cubef7.html}
+                {STM32Cube SDK}
+            \li \l{https://www.st.com/en/development-tools/stm32cubeprog.html}
+                {STM32Cube Programmer}
+        \endlist
+        \li For NXP boards:
+        \list
+            \li \l{https://www.nxp.com/design/development-boards/i.mx-evaluation-and-development-boards/i.mx-rt1050-evaluation-kit:MIMXRT1050-EVK}
+                NXP EVKB-IMXRT 1050 SDK
+            \li \l{https://www.segger.com/downloads/jlink}{SEGGER JLink}
+        \endlist

+            \uicontrol {Device Support} > \uicontrol {Bare Metal} and
+            \uicontrol {MCU Support} to enable the Bare Metal and MCU
+            plugins.
+        \li Restart \QC to be able to use the plugins.
+        \li Create connections for debugging on the MCU board, as described in
+            \l{Connecting Bare Metal Devices}.

+
+    \section2 Adding MCU Devices
+
+    \QC automatically adds a default MCU device when you select
+    \uicontrol Apply in the \uicontrol MCU tab after configuring the
+    MCU tool chain.
+
+    \image qtcreator-mcu-device.png "MCU devices"
+
+    To add MCU devices, select \uicontrol Tools > \uicontrol Options >

+            the kit.
+        \li Select \uicontrol Apply to add the kit.
+    \endlist
+
+    \section1 Running Applications on MCUs
+
+    You can use a wizard to set up a project for developing an application that
+    you can run on MCUs. The project uses a subset of QML and Qt Quick Controls
+    that are supported by Qt for MCUs. For more information about developing
+    applications for MCUs, see the Qt for MCU documentation.
+
+    To create an application and run it on a MCU board:
+
+    \list 1
+        \li Select \uicontrol File > \uicontrol {New File or Project} >
+            \uicontrol Application > \uicontrol {MCU Support Application} >

+        \li Follow the instructions of the wizard to create the project.
+        \li Select \uicontrol Projects > \uicontrol {Build & Run}, and then
+            select the kit for building the application and running it on the
+            MCU board specified in the kit.
+        \li Select \uicontrol Run to specify run settings.
+            Usually, you can use the default settings.
