| 2 | GND | ground | |
| 3 | CS | LCD chip select signal, low level enable | |
| 4 | RESET | LCD screen reset signal, low level reset | |
| 5 | DC/RS | LCD screen register/data selection signal, 0: register, 1. data | |
| 6 | SDI(MOSI) | SPI bus write data signal | |
| 7 | SCK | SPI bus clock signal | |
| 8 | LED | Backlight control, high level lights up, if no control is needed, connect to 3.3V to keep it on | |
| 9 | SDO(MISO) | SPI Bus read data signal, if no reading function is needed, it does not need to be connected | |
| 10 | T_CLK | Touch SPI bus clock signal | |
| 11 | T_CS | Touch screen chip select signal, low level enable | |
| 12 | T_DIN | Touch SPI bus input | |
| 13 | T_DO | Touch SPI bus output | |
| 14 | T_IRQ | Touch screen interrupt signal, low level when touch is detected |
