WL0F00043000WGXAANA00 is a 4.3-inch HMI display development board designed for engineers developing industrial control and graphical user interface applications. The board integrates a 4.3-inch IPS TFT LCD module with capacitive touch and a high-performance STM32U599ZIT6 MCU, providing a ready-to-use hardware platform for rapid HMI prototyping and system evaluation.
The display features 480×272 resolution, wide viewing angles (80/80/80/80), and typical brightness of 400 cd/m², delivering clear and stable visual performance for control panels and embedded interfaces. The integrated capacitive touch panel communicates through an I²C interface for responsive user interaction.
Powered by the ultra-low-power STM32U599 series MCU, the MCU integrates 2MB Flash and approximately 2.5MB SRAM, along with a built-in GPU2D accelerator and LTDC display controller for efficient GUI rendering. An additional 16MB external serial flash provides storage for fonts, images, and other graphical resources used in HMI applications.
The board supports multiple communication interfaces including RS485, UART, SPI, I²C, and USB Type-C (USB 2.0 OTG), along with a Micro SD card slot and wide input voltage support (5–28V DC). The platform is compatible with the STM32 development ecosystem including STM32CubeMX, STM32CubeIDE, STM32CubeProgrammer, and TouchGFX Designer, enabling developers to efficiently design graphical interfaces and integrate the board into embedded systems.
