| Serial number | symbol | explanation |
| 1 | DC | In the parallel port mode, it serves as the data and command control pins; in the SPI mode, it acts as the SPI clock line. |
| 2 | CS | The chip select is effective when the level is low. |
| 3 | RD | And read aloud |
| 4 | SDC | When using the parallel interface, it is written as the parallel interface; when using SPI communication, it is written as the SPI DC pin. |
| 5 | D0 | Parallel port data D0 |
| 6 | SDA | SPI communication data line |
| 7 | D2 | Parallel port data D2 |
| 8 | D1 | Parallel port data D1 |
| 9 | D4 | Parallel port data D4 |
| 10 | D3 | Parallel port data D3 |
| 11 | RES | Reset - Low level active |
| 12 | D5 | Parallel port data D5 |
| 13 | D7 | Parallel port data D7 |
| 14 | D6 | Parallel port data D6 |
| 15 | BLK | Backlight, by default, can be left unconnected. Low level - turn off the backlight. |
| 16 | TE | Used for synchronization, it is generally not necessary in most cases. |
| 17 | VCC | Power supply: 3.3V |
| 18 | GND | Power ground terminal |
