- Data The 1602 has a standard 16 - pin interface, details are as follows: Pin 1 (VSS): It serves as the ground power. Pin 2 (VDD): Connect to a 5V positive power supply. Pin 3 (V0): It is the LCD contrast adjustment terminal. When connected to the positive power supply, the contrast is the weakest; when grounded, the contrast is the highest. Excessive contrast may cause "ghosting". Use a 10K potentiometer to adjust the contrast during operation. Pin 4 (RS): It is for register selection. A high - level signal selects the data register, while a low - level signal selects the instruction register. Pin 5 (R/W): It functions as the read/write signal line. A high - level signal indicates a read operation, and a low - level signal indicates a write operation. Pin 6 (E): It is the enable terminal. When the E terminal transitions from high level to low level, the LCD module executes the command. Pins 7 - 14 (D0 - D7): They are 8 - bit bidirectional data lines. Pin 15: Connect to the positive power supply for the backlight. Pin 16: Connect to the negative power supply for the backlight.
