This 1.9-inch IPS TFT LCD Display Module is designed for makers, hobbyists, and engineers who need a compact yet high-clarity visual interface. Powered by the ST7789 driver IC, this display delivers bright colors, wide viewing angles, and smooth graphics. It is ideal for Arduino, ESP32, STM32, Raspberry Pi Pico, and other microcontroller projects that require a reliable and vibrant screen. Key Features High Resolution Display: 170×320 pixels with sharp text and smooth graphics. IPS Wide Viewing Angle: Consistent colors and clarity from all directions. Space-Saving SPI Interface: 4-wire SPI reduces the number of GPIO pins needed. 3.3V Logic Compatible: Works directly with modern MCUs like ESP32 & RP2040. Backlight Control: BLK pin allows PWM dimming or ON/OFF control.
