Enjoy the freedom to develop your application on PC even before the actual hardware is ready for deployment. By decoupling UI app development from deployment and testing on target, Qt for MCUs allows great flexibility and major time savings.
Boost your productivity by importing designs straight from Figma, Photoshop, and other content authoring tools and automatically converting them into functional code. Qt Design Studio allows UI/UX designers to bring their designs to life with compelling animations, simulation tools, and web sharing capabilities.Qt Design Studio
Scale across markets and regions with advanced Internationalization and Localization tools helping you translate your software to any language—including right-to-left, bidirectional scripts, complex diacritics, scriptio continua, etc.
X2D 100C camera uses Qt on both its touch displays, including Qt for MCUs on its new 1.08-inch colored top display, reporting the camera status and shooting parameters.
"Qt was a game-changer for us in creating the microdisplay for our new camera. Despite the initial challenges we faced with memory, fonts, and layout, the direct support from Qt Group was exceptional. We were able to effectively leverage the wealth of online cases in the Qt community and achieve outstanding results."

"In our field, high accuracy, full reliability, and finesse in design go hand in hand with top performance—low memory footprint and instant boot, foremost—all features that Qt for MCUs includes out of the box."
ESAB, world leader in welding and cutting equipment, chose Qt for MCUs for its welding machines. The easily readable, intuitive TFT display built with Qt includes a wealth of controls to fine tune the welds for optimal performance—this time using physical knobs, for better interaction with gloves and protections.
"For us, QML has been a great asset both for creating prototypes on desktop that we could readily test on target and for ensuring full scalability across classes of hardware, from low-end microcontrollers to high-end microprocessors."
"When we started developing our touchscreen multi-function controller on an NXP i.MX RT1170 board, we had concerns about the hardware capabilities for our use case. It was a great relief to see that Qt for MCUs allowed us to efficiently deploy all the planned functionalities and to do so in half the expected time.
Thanks to Qt separation of hardware and software development, it was easy to view and test the UI on our desktops and deploy it to the actual hardware only for testing the performance. This saved us a lot of time and effort."
