Product Description
Description
The LCD1602 is an industrial character LCD that can display 16x2 or 32 characters at the same time.
The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage, that is, the graphic can be displayed.
The 1602 uses a standard 16-pin interface, and our display module is a module that provides I2C functionality.
I2C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL),pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted. It can be operated as long as it supports the I2C development board.
For example, the common Ar-duino, raspberry pi, Stm32 and so on.
Features: Easy to use; Less I/O ports are occupied; Support IIC Protocol; The I2C LCD1602 library is easy to get; With a potentiometer used to adjust backlight and contrast; Blue backlight; Power supply: 5v; I2C address is: 0x27.
How to connect it to Raspberry Pi and Ar-duino
Compatibility
Used for connecting Ar-duino and Raspberry pi and it can be used to display real time clock, temperature, humidity etc.
(A potentiometer is also necessary to adjust the contrast. Working Voltage: Only 5V )
You can display the digital information or English sentense on the LCD screen by using Arduino, Raspberry Pi or other MCU which supports i2c protocol.

Default Address
0x27 for PCF8574T chip; 0x3F for PCF8574AT chip; please check which chip you have on i2c interface.
(Before you upload the code to the control board, please download the LiquidCrystal_I2C library)

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

1. The LiquidCrystal_I2C library available from within the Arduino app works fine. You don't need any of the variant versions. Just go into the Library Manager and search for LiquidCrystal I2C. The default one by Frank deBrabander works great. The warning "THIS LIBRARY MIGHT NOT BE COMPATIBLE WITH EXISTING SKETCHES" is probably valid, but I had no issues.
2. Be sure to check the pin order on the I2C thing. They are labeled. Don't just trust pictures in tutorials.
3. The device ID on mine was indeed 0x27. Apparently there is at least one other commonly used value possible, 0x3F. I saw nothing on my display initially, so I tried the I2C scanner on Instructables, which confirmed mine was indeed 0x27. Moral of the story? The potentiometer on the back is very important! Once you're sure your device ID is correct, adjust brightness.
Very good deal for what it is - 16x2 characters, nice and bright, and only requires 4 pins (2 of which are power and ground).
Preforms good for price and requires only 4 wire to use ! works with both Arduino and Raspberry

Easy to install and program.
Comes with the 12C adapter so you can plug it in instead of soldering.
Pros:
-The 2 pin I2C connection is so much easier than the alternatives you see with all sorts of wires trailing off.
-The screen is bright and vibrant. Perfect for a simple menu or readout
-The controller board is conveniently soldered to the display. Plug and play is painless.
Cons (Sort of):
-The wiki doesn't give much detail about which library to use or where to download it from. It says LiquidCrystal_I2C, but when you search for that, you get a bunch of different results. It took me 3 tries to find the right one. Search through Arduino IDE, scroll a ways, and you'll see one that matches verbatim. (Not a huge con honestly, it's just giving the author would have been nice).
-The only other con is common to all displays like these. 16 character 2 line displays are pretty limiting to what you can do with them, but again, as long as you count out the letters you want before purchasing, you'll be fine. These things are great.
