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. compatible with 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.

Note: You need to solder the Pin Headers before application.

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

5 Stars
Display works fine.
I used it for a rotary encoder reader to mesaure angle with a R02040 Pico. It worked fine, just a little bit slow due to the use of I2C. Nice brightness and easy to set up.

5.0 out of 5 stars Does the job - at a good price
Reviewed in the United States on December 3, 2020
But
1) They don't give you the pin out - just a Fritz 'picture' of the circuit board. I made the pin out table, in the attached picture
2) Their sample code is overly complicated if you are using this as one of your first LCD tools (as I am).
Just try
lcd.print(" Hello World!") ;
lcd.scrollDisplayLeft() ;
delay(250) ;
lcd.scrollDisplayLeft() ;
delay(250) ;
lcd.scrollDisplayLeft() ;
// etc. Actually, put the above in a loop, but I don't want to complicate the example.
