The 1.28-inch Round LCD Display Module with Touch Panel is a compact and versatile display solution ideal for a wide range of applications. It features a sharp and vibrant 240×240 resolution IPS display that supports 65K colors, ensuring clear and detailed visuals with excellent color reproduction and wide viewing angles. The capacitive touch panel, controlled by the CST816S chip, offers high sensitivity and fast response times, making it suitable for applications requiring quick and accurate touch input. The touch panel is constructed with surface-toughened glass and thin film material, providing durability and robustness for repeated use. The module utilizes a 4-wire Serial Peripheral Interface (SPI) for display communication, simplifying connections and reducing the number of GPIO pins required. SPI is known for its high-speed data transfer capabilities, making it suitable for high-performance applications. The touch control uses the Inter-Integrated Circuit (I2C) protocol, designed for simplicity and ease of integration with microcontrollers. The CST816S touch chip supports a configurable communication rate of 10Khz to 400Khz, offering flexibility for various system requirements. Compatible with popular microcontroller platforms such as Raspberry Pi, Raspberry Pi Pico, Arduino, and STM32, this display module is a versatile choice for hobbyists, educators, and developers. It comes with comprehensive online resources, including manuals, example codes, and development guides, to streamline the setup process and enable quick prototyping and deployment.
