The touch display module, a 1.54-inch color TFT LCD, offers a resolution of 240x240 pixels and is equipped with a capacitive touch panel, making it ideal for a variety of applications that require a compact and interactive display.
It uses IPS technology to ensure a wide viewing angle of 80° in all directions, delivering clear images and vivid colors from any perspective.
It integrates the ST7789V driver and the 4-wire SPI interface for the display part and for the touch part it integrates the CST816D which requires the use of IIC (SCL and SDA).
Its small size makes it suitable for portable device projects or where space is limited.
The display comes mounted on the module to facilitate its use with various development boards and has standard 2.54mm pins, making it compatible with Breadboard.
