4.45 Inch TFT LCD Display Module ST7701 Driver 480*854 RGB Interface Color Screen

4.45 Inch TFT LCD Display Module ST7701 Driver 480*854 Resolution RGB Interface Color Screen For Arduino delivers sharp, high-resolution graphics and vibrant color rendering for embedded systems, smart control panels, and maker projects. This display features an IPS panel driven by the robust Sitronix ST7701 controller, supporting a crisp 480×854 pixel FWVGA resolution. Furthermore, the module utilizes a high-speed parallel RGB interface alongside a 3-wire SPI configuration channel to ensure fluid video playback and responsive graphical refresh rates. Consequently, users experience smooth animations and clear text rendering across broad viewing angles. Therefore, this color screen serves as an excellent upgrade for advanced microcontroller and microprocessor platforms including the ESP32-S3, STM32, Arduino, and single-board computers.

Key Features:

• High-Resolution Visuals: Delivers 480×854 pixels on a 4.45-inch display surface, ensuring crisp text, icons, and graphical user interfaces.
• Full-View IPS Technology: Offers wide symmetrical viewing angles up to ≈ 160° with consistent color accuracy and strong contrast.
• Dual Interface Architecture: Combines a 3-wire SPI bus for initial register setup with a high-throughput parallel RGB interface for continuous video streaming.
• Rich Color Depth: Renders up to 16.7 million colors (24-bit RGB) to reproduce vivid photographs, gauges, and interactive menus.
• Integrated Backlight: Features a high-efficiency white LED backlight array that provides clear visibility under various ambient lighting conditions.

Pinout and Wiring:

• VDD / VDDI: Supplies 3.3V power to the ST7701 logic core and I/O lines.
• GND: Connects to the system common ground reference.
• CS / SDA / SCL: Provide the 3-wire SPI communication lines to configure registers upon system startup.
• RESET: Serves as the active-low hardware reset signal to initialize display registers.
• PCLK / DOTCLK: Receives the pixel clock synchronization pulse for continuous RGB data streaming.
• HSYNC / VSYNC: Receive horizontal and vertical sync pulses for raster framing.
• ENABLE (DE): Receives the data enable strobe to define active pixel scan regions.
