Description
This 4.0-inch SPI module, equipped with ST7796U driver chip, brings you a delicate display with 320x480 resolution and 16.7M colors, clear images, rich colors, and sharp text. Capacitive touch technology makes interactive operations smooth and natural. The onboard level conversion circuit is compatible with 5V and 3.3V MCUs, and can easily adapt to various microcontrollers. The 4-wire SPI serial bus design saves I/O pin resources, simplifies hardware design, and improves system integration. The input interface provides two options: 2.54 pin headers and FPC extension interfaces, which meet the connection requirements in different scenarios and are flexible and changeable.
It comes with a micro TF card slot for easy expansion of storage space, whether it is storing a large number of pictures, videos, or complex program codes, it can easily cope with it. Whether it is a beginner or an experienced developer, you can quickly get started and easily start the project development journey.
Whether you are engaged in intelligent hardware development or industrial automation applications, this module can provide you with a stable, efficient and convenient display solution, and is an ideal choice for your project development.
