ST7735 8P 128X160 SPI 1.8 Inch TFT LCD Screen Display Module

ST7735 8P 128X160 SPI 1.8 Inch TFT LCD Screen Display Module is a versatile, high-resolution color display designed for embedded systems and DIY electronics projects. This module utilizes the robust ST7735 driver IC to deliver 16-bit full-color graphics across a 1.8-inch diagonal screen. Consequently, it offers a significant visual upgrade over traditional monochrome character displays. By employing a high-speed Serial Peripheral Interface (SPI), the module requires only a few GPIO pins from your microcontroller. Furthermore, the integrated SD card slot on the rear provides a convenient method for storing and loading large image assets. Therefore, you can easily integrate this display into Arduino, ESP32, or STM32 platforms to create professional-grade user interfaces and data monitors.

Key Features:

• Vibrant Full-Color Output: Supports up to 65K colors (RGB 5-6-5), ensuring that your icons, charts, and text appear sharp and professionally rendered.
• High-Speed SPI Interface: Uses a 4-wire serial interface to maintain high frame rates while minimizing the wiring complexity for the host controller.
• Built-in SD Card Slot: Features a dedicated micro-SD slot for data logging or storing bitmap images, which significantly expands the storage capabilities of your project.
• Wide Viewing Angle: The Thin Film Transistor (TFT) technology provides better contrast and wider viewing angles compared to standard STN displays.
• Flexible Power Compatibility: Operates efficiently on 3.3 V logic, however, many versions include an on-board regulator for 5 V compatibility.
