The most powerful Pi yet - perfect for LVGL development and embedded displays
The Raspberry Pi 5 represents a significant leap forward in single-board computing, making it an excellent choice for LVGL development projects. With its improved graphics performance, increased memory bandwidth, and enhanced I/O capabilities, the Pi 5 is well-suited for creating sophisticated embedded user interfaces.
Released in October 2023, this latest iteration addresses many of the limitations that developers faced with previous Pi models when working with graphics-intensive applications like LVGL. The combination of a more powerful CPU, improved GPU, and faster memory makes it capable of handling complex UI animations and high-resolution displays.
The Raspberry Pi 5 excels in LVGL development scenarios, offering substantial improvements over its predecessor. Our testing focused on common embedded UI workloads and real-world applications.
Consistent 60 FPS achieved with complex UI animations and multiple widgets. The VideoCore VII GPU handles LVGL rendering efficiently, even with alpha blending and anti-aliasing enabled.
LVGL runtime memory usage is impressively low. A typical application with 50+ widgets uses approximately 2.1MB of RAM, leaving plenty of headroom for application logic.
CPU usage remains low during UI operations, typically around 15% for active rendering. This allows for concurrent background tasks without impacting UI responsiveness.
Supports resolutions up to 4K@60Hz. Tested successfully with SPI, I2C, and parallel display interfaces. Excellent compatibility with touch screens and capacitive displays.

} The Raspberry Pi 5 is an excellent choice for LVGL development projects that require high performance and flexibility. Its improved graphics capabilities, increased memory bandwidth, and enhanced I/O make it well-suited for creating sophisticated embedded user interfaces.
For developers working on projects that need smooth animations, high-resolution displays, or complex UI layouts, the Pi 5 provides the necessary performance headroom. The backward compatibility with Pi 4 accessories and the extensive community support make it a safe investment for both new and existing projects.
Best suited for: Complex LVGL applications, high-resolution displays, projects requiring smooth animations, development and prototyping.
