Touch and its controller: This touch screen is composed of surface tempered glass + thin film FILM material, which has high strength, strong hardness and good light transmittance. The matching driver chip is CST816D self-capacitive touch chip, which supports standard I2C Communication protocol standard, which can achieve configurable communication rates of 10Khz~400Khz. I2C communication protocol: The 7-bit device address of the chip is 0x15, that is, the device write address is 0x2A and the read address is 0x2B. 240x280 resolution, 262K colors, clear and colorful displaying effect. High touch screen transmittance, fast response and long lifetime. Embedded ST7789V2 driver chip and CST816T capacitive touch control chip, using SPI and I2C communication respectively, minimizes required IO pins, supports controller boards like for Raspberry Pi / ESP32S3 / for Raspberry Pi Pico / for Arduino / STM32. Note: Please ensure that the power supply voltage and logic voltage are consistent, otherwise it will not work properly.<br><br>Specifications: OPERATING VOLTAGE: 3.3V / 5V RESOLUTION: 240 x 280 pixels DISPLAY DRIVER: ST7789V2 TOUCH DRIVER: CST816T DISPLAY INTERFACE: 4-wire SPI TOUCH INTERFACE: I2C DISPLAY PANEL: IPS TOUCH TYPE: Capacitive DISPLAY SIZE: 27.972 x 32.634mm PIXEL SIZE: 0.11655 x 0.11655mm MODULE SIZE: 33.13 x 41.13mm Different batches may have different appearance, which does not affect use. color: Black Material: Tempered glass + film FILM<br><br>Package Contents: 1 x 1.69inch Touch LCD Module 1 x GH1.25 12Pin cable<br><br>Only the above package content, other products are not included.
