WF43WTYBEDST0 is a 4.3-inch IPS TFT-LCD display with a Resistive Touch screen, made of resolution 480x272 pixels. This module is built-in with BT816 controller IC, and it supports SPI and QSPI interfaces. The QSPI interface can achieve four times data rate compared with the current SPI interface and make a smoother display accordingly. The series of BT815/6 controller IC with EVE (Embedded Video Engine) technology simplifies the system architecture, Eve technology is a revolutionary concept that utilizes an object-oriented approach to creating high-quality human-machine interfaces (HMI). This new technology supports display, audio and touch, enabling engineers to quickly and efficiently design HMI and provide a powerful solution for high-resolution displays that reduce material costs.

WF43WTYBEDST0 is adopted IPS panel which is having the advantage of wider view angle of Left:80 / Right:80 / Up:80 / Down:80 degree (typical), contrast ratio 800:1 (typical value), brightness 350 nits (typical value), anti-glare surface panel, aspect ratio 16:9.

We offer the TFT module WF43WTYBEDST0#000 designed to support the Arduino board. The control signal for WF43WTYBEDST0 is 3.3V; it has a built-in storage device (FLASH 32M). The control signal of WF43WTYBEDST0#000 is 5V; without a built-in storage device (FLASH); but with a MicroSD Socket, pins CON1~CON4 are designed for SPI control (such as for Arduino Uno Rev3). WF43W model can be operating at temperatures from -20℃ to+ 70℃ and storage temperatures from -30℃ to +80℃.
