The WF43WTYBEDST0 is a 4.3-inch IPS TFT-LCD display module with a resistive touch screen and a resolution of 480x272 pixels. This module features a built-in BT816 controller board and supports both SPI and QSPI interfaces. The QSPI interface offers data transfer rates up to four times faster than the standard SPI, resulting in smoother display performance.
The BT815/BT816 series controller IC incorporates EVE (Embedded Video Engine) technology, simplifying the system architecture. EVE is a revolutionary approach that uses an object-oriented methodology to create high-quality human-machine interfaces (HMIs). This technology supports display, audio, and touch functions, enabling engineers to quickly and efficiently design HMIs while reducing material costs.
The WF43WTYBEDST0 uses an IPS panel, providing wide viewing angles: 80° (left), 80° (right), 80° (up), and 80° (down) (typical). It has a contrast ratio of 800:1 (typical) and a brightness of 350 nits (typical). The anti-glare surface ensures clear visibility in various lighting conditions, while the 16:9 aspect ratio makes it ideal for multimedia applications.
We offer the WF43WTYBEDST0#000 model, designed for compatibility with Arduino boards. The WF43WTYBEDST0 operates with a 3.3V control signal and includes 32MB of built-in FLASH storage. The WF43WTYBEDST0#000 model, however, operates with a 5V control signal, does not include built-in FLASH storage, and supports a MicroSD socket. Additionally, the WF43WTYBEDST0#000 model is designed with CON1 to CON4 pins for SPI control, making it compatible with Arduino Uno Rev3 and similar boards.
The WF43WTYBEDST0 operates within a temperature range of -20°C to +70°C and can be stored at temperatures between -30°C and +80°C, making it suitable for a wide range of environments.
