1.83inch Touch LCD Module
The 1.83inch Touch LCD Module is a 1.83inch IPS color touch screen module. It features a high-definition resolution of 240×284 pixels, supports 262K true-to-life colors, delivering clear, detailed images and excellent visual performance. Equipped with a high-transmittance capacitive touch panel, it offers responsive touch feedback and long operational life. The module integrates the ST7789P display driver IC and the CST816D capacitive touch IC, communicating via SPI and I2C interfaces respectively, which minimizes pin usage and simplifies hardware integration. An onboard level shifter ensures compatibility with both 3.3V and 5V power inputs, allowing seamless connection to mainstream controller platforms such as Raspberry Pi, ESP32, Pico, Arduino, and STM32.
