Product description
Introduction:
LCD1602 is an industrial character type LCD that can show 16*2, i.e. 32 characters. The character generator ROM in the LCD module has already stored 160 different characters in dot matrix, including Arabic numbers, letters in low and upper case, and common symbols.
In Arduino IDE, a built-in library LiquidCrystal can be called directly, and you don’t need to write it, which is pretty convenient for beginners.
Its working voltage is 5V, and you can adjust the contrast via the 50K potentiometer. For the backlight, just connect pin A to 3.3V and K to GND, and then it will light up.

LCD display module with blue backlight
Wide viewing angle and high contrast
Built-in industry standard HD44780 equivalent LCD controller
LCM type: Characters
Can display 2-lines x 16-characters
Operate with 5V DC
Material: FR4 + LCD

Pins of LCD1602 and their functions:
VSS: connected to ground
VDD: connected to a +5V power supply
VO: to adjust the contrast
RS: A register select pin that controls where in the LCD’s memory you are writing data to. You can select either the data register, which holds what goes on the screen, or an instruction register, which is where the LCD’s controller looks for instructions on what to do next.
R/W: A Read/Write pin to select between reading and writing mode
E: An enabling pin that, when low-level energy is supplied, causes the LDC module to execute relevant instructions. D0-D7: to read and write data
A and K: Pins that control the LCD backlight
