WF43WTYBEDSG0 is a 4.3-inch IPS TFT-LCD display with a capacitive touch screen, offering a resolution of 480x272 pixels. This module includes a built-in controller board, making system integration easier. It is equipped with the BT815 controller IC and supports both SPI and QSPI interfaces. The QSPI interface achieves a data rate up to four times faster than the standard SPI interface, providing smoother display performance. The BT815/BT816 series controller IC, integrated with EVE (Embedded Video Engine) technology, simplifies system architecture. EVE is a revolutionary concept that uses an object-oriented approach to create high-quality human-machine interfaces (HMIs). This technology supports display, audio, and touch, enabling engineers to quickly and efficiently design HMIs while providing a powerful solution for high-resolution displays and reducing material costs.
The WF43WTYBEDSG0 features an IPS panel, offering a wide viewing angle: Left: 80° / Right: 80° / Up: 80° / Down: 80° (typical). It has a contrast ratio of 800:1 (typical) and a brightness of 400 nits (typical). The display has an aspect ratio of 16:9. The PCAP touch screen is integrated with an ILI2130 IC, supporting an I2C interface and 5-point touch functionality.
WF43WTYBEDSG0#000 Arduino TFT 4.3" Display
We offer the WF43WTYBEDSG0#000 4.3" TFT Display, specifically designed for use with Arduino boards and fully compatible with Arduino-based projects. This model is fully compatible with Arduino Uno Rev3 and other Arduino boards.
The WF43WTYBEDSG0 model features a 3.3V control signal and includes a built-in 32MB Flash storage device, making it ideal for lower-storage applications.
In contrast, the WF43WTYBEDSG0#000 model uses a 5V control signal, lacks a built-in Flash storage device, but includes a MicroSD socket for additional storage, making it suitable for Arduino display setups.
Pins CON1–CON4 are designed for SPI control, ensuring easy integration with Arduino display setups, such as those using Arduino Uno Rev3.
