عن هذا المنتج
TFT LCD Display 1.47" (ST7789 SPI - 8 Pin)
The 1.47-inch TFT LCD is a high-performance, compact display module known for its elongated "stretched" aspect ratio and exceptional clarity. Utilizing IPS (In-Plane Switching) technology, it provides vibrant 18-bit color and superior viewing angles compared to standard TFT screens. Driven by the reliable ST7789 controller, it communicates via a high-speed SPI interface, making it perfect for modern microcontrollers like the ESP32, STM32, or Arduino.
Key Features
High Pixel Density: A resolution of 172 x 320 pixels in a small 1.47" frame ensures sharp text and detailed graphics.
IPS Technology: Offers 80°+ viewing angles from all directions with consistent color reproduction.
Full Color Depth: Supports up to 262,144 colors (18-bit), delivering rich and accurate visuals.
Flexible Integration: The unsoldered headers allow for a low-profile fit in custom enclosures or permanent soldering to PCBs.
Universal Power: Compatible with both 3.3V and 5V power supplies, simplifying your circuit design.
