Expert LVGL GUI Development Services
Your hardware is resource-constrained. Your UI doesn't have to be. Gravitonic uses LVGL to build beautiful, smartphone-like GUIs that run flawlessly on low-cost, low-power microcontrollers.
Don't let a bad UI make your product feel cheap.
Your Hardware is Low-Cost. Your UI Shouldn't Look Like It.
You face a critical dilemma: you need a modern, beautiful UI to compete, but your product's BOM (Bill of Materials) cost can't support a high-power MPU, 512MB of RAM, and an Embedded Linux stack.
Hiring a generic developer or trying to do it in-house leads to predictable failures:
The "MPU vs. MCU" Trap
You believe you must use a powerful, expensive MPU (like an NXP i.MX 8) and Qt just to get a good-looking interface, which destroys your target price point.
Dated, Clunky Interfaces
Your product is stuck with a 10-year-old, text-based, or blocky graphical display. It's functional, but it looks cheap, and your competitors are launching beautiful, touch-based UIs.
The Firmware-to-Design Gap
Your hardware engineers are brilliant at C and firmware logic, but they are not UI/UX designers. They can't translate a Figma mockup into a fluid, beautiful, and efficient LVGL interface, resulting in a UI that feels clunky and amateurish.
Poor Performance & High Footprint
Your team's first attempt at LVGL is slow, uses too much RAM, and flickers. They don't know how to optimize framebuffers, assets, and rendering loops to get fluid performance on a constrained MCU.
Our End-to-End LVGL Development Services
Gravitonic is your specialist LVGL partner. We are embedded engineers and UI/UX designers. We deliver the high-end feel of a smartphone on the hardware you can actually afford.
1. UI/UX Design for Microcontrollers
We design beautiful, modern UIs within the constraints of LVGL and your MCU. Our designers know what is (and isn't) possible, creating pixel-perfect, intuitive interfaces that are highly optimized for a low-power, low-memory environment.
2. LVGL Development & Integration
We write the clean, efficient, and maintainable C code to bring your UI to life. We integrate LVGL with your hardware, your chosen RTOS (FreeRTOS, Zephyr), or on a bare-metal system, connecting it seamlessly to your business logic.
3. Performance & Footprint Optimization
This is our specialty. We are obsessive optimizers. We fine-tune your LVGL implementation to get the absolute maximum performance from the minimum RAM and ROM footprint, enabling fluid, 60-fps animations on hardware other teams say is "too slow."
4. Custom LVGL Widget & Driver Development
Need a feature that LVGL doesn't support out-of-the-box? We can write custom, high-performance widgets for complex data visualization. We also write the low-level display and touch drivers to get LVGL running on your specific custom hardware.

Why Gravitonic? We Make MCUs Look Like MPUs.
Why do some of the most innovative hardware companies choose Gravitonic for their LVGL projects? Because we are the rare team that bridges the gap between firmware and world-class design.
Maximize Your BOM Value
We deliver a premium, high-end user experience on hardware that costs a fraction of a Linux-based MPU system. This allows you to win your market on both features and price.
We are C-Programmers and Designers
We are the single team that speaks both Figma and C (firmware). Our designers create assets that are pre-optimized for LVGL, and our C developers implement them pixel-for-pixel. This unified team eliminates the integration risk.
Deep RTOS & Hardware Expertise
We are not just app developers. We are low-level embedded engineers. We know FreeRTOS, Zephyr, STM32, ESP32, and NXP. We understand DMA, SPI, and I2C—the building blocks of a high-performance system.
Accelerate Your Time-to-Market
By leveraging LVGL and our in-house experts, we can develop your complete, market-ready UI in a fraction of the time it would take to build a custom stack from scratch or port a heavy framework like Qt.
The LVGL & Microcontroller Stack
Gravitonic is expert in the entire resource-constrained ecosystem.

Frequently Asked Questions (FAQ)
When should I choose LVGL instead of Qt?
The choice is simple: LVGL is for Microcontrollers (MCUs). Qt is for Microprocessors (MPUs). If your product runs an RTOS (like FreeRTOS) or bare-metal C, has limited RAM (e.g., < 1MB), and needs to be low-cost and low-power, LVGL is the perfect choice. If you have a powerful MPU (e.g., > 512MB RAM) running Embedded Linux, Qt is the better solution. We are experts in both.
What is SquareLine Studio, and do you use it?
SquareLine Studio is the official drag-and-drop UI builder for LVGL. We use it as a powerful tool for rapid prototyping and building the foundational UI. We then go beyond SquareLine, writing custom C code to implement complex logic, optimize performance, and integrate the UI with the rest of your firmware.
How much RAM/ROM do I really need for LVGL?
LVGL is incredibly light. It can run with as little as 32KB of RAM and 128KB of Flash, but a more realistic, beautiful UI will perform well with ~256-512KB of RAM. We are experts at profiling your exact UI design to give you a precise memory footprint.
Can you make LVGL look as good as an iPhone?
Yes. LVGL is a powerful rendering engine. When combined with our expert UI designers and optimization engineers, we can create UIs with modern animations, vector graphics, and anti-aliasing that truly rival the look and feel of a premium smartphone.
