Hardware Configuration

The LCD module hardware circuit comprises two parts: an LCD display control circuit and a backlight control circuit.
The LCD display control circuit is used to control the pins of the LCD, including control pins and data transfer pins.
if the backlight is not required to be be on and off, can be directly connected to the 3.3V if the backlight is not required to be be on and off, can be directly connected to the 3.3V power supply.
