Introduction

Most of the 2.4-inch to 3.5-inch LCD-TFT displays (bare screen modules) on the market that use 40Pin FPC cables as physical interfaces use this same set of wire sequences:

Under normal circumstances, this set of line sequences can be configured as 4-Line SPI, 3-Line SPI, 8bit 8080 and 16bit 8080 interfaces by configuring the IM pin. This adapter board leads out the 4-Line SPI communication pins and IM configuration pins of this set of interfaces, making it convenient to test the LCD module or use it for development.

In addition to the transfer circuit, the module is also equipped with an NS2009 touch screen controller with an I2C interface that can support LCD modules with resistive touch screens.

At the same time, this module is adapted to the BL706 core board of Nanjing Boliu Technology. The core board can be directly connected to the module through pin headers to provide the LCD display function for the BL706 module.

characteristic
