4.Requirements
Â
To ensure the normal operation and optimal display effect of the 1602 LCD screen, you need to pay attention to the following usage requirements:
Power Supply Voltage: Depending on the specific model, it is usually 3.3V or 5V, and it must be ensured to match the controller level.
Control Interface: Confirm the control interface used, such as parallel interface (usually requires multiple control pins) or serial interface (saves control pins but slower speed).
Environmental Conditions: Avoid long-term exposure to high temperature, high humidity, and dusty environments to avoid affecting the LCD display effect and life.
