ST7789 is a compact TFT color display module that supports 65,000 colors with 240x240 pixel resolution. It communicates with Arduino and ESP series boards via SPI protocol. Compared to OLED displays, it offers a much larger viewing area and full color graphics support, making it preferred for applications where color and visual detail are at the forefront, such as user interfaces, sensor data visualization and game projects. When used with ESP32, smooth animation and graphic display is possible.
