Anyone who has worked with Arduino, ESP32, or similar microcontrollers has run into the same issue sooner or later: you want to display information quickly, but your available I/O pins are running out, the wiring becomes messy, and you just want something that works without frustration. That’s exactly why the LCD1602 I2C display module shows up so often in the questions I receive.
This website exists because of the many questions people used to ask via the old VraagAlex website about ordering from AliExpress.
“We are not an official AliExpress customer service, but we are happy to help you with questions about this product or your order.”
You’ll see this display used by beginners, hobbyists, and even in serious prototype builds. Not because it’s fancy, but because it’s reliable, practical, and easy to integrate.
So what exactly is the LCD1602 I2C?
The LCD1602 is a character display capable of showing 2 lines of 16 characters. It’s ideal for displaying temperatures, system states, menus, error messages, or simple status information. What makes this version special is the built-in I2C adapter (PCF8574).
Thanks to I2C, you only need 4 connections: VCC, GND, SDA, and SCL. A classic LCD1602 without I2C can require up to 7 GPIO pins. With this module, you save 5 valuable pins, which makes a big difference once you start adding sensors, relays, or SD cards.
Why this AliExpress version is so popular
With over 10,000 units sold and 2,277 reviews averaging 4.8 stars, this is one of those rare AliExpress products where user experiences are remarkably consistent. Buyers frequently mention:
— clear, easy-to-read display (blue or green)
— fast delivery
— works immediately with common Arduino libraries
— neat and secure packaging
— real GPIO savings thanks to I2C
One reviewer noted that after connecting the module, they only had to slightly adjust the contrast potentiometer on the back and everything worked right away. That’s exactly what you want from a module at this price point.
Price, VAT, and no hidden surprises
The price starts at around €1.42 including VAT. Yes, VAT included.
That matters, because in the past things were different. Extra charges for customs or handling could appear after delivery. Today, AliExpress collects VAT upfront. What you see when ordering through

is the final amount you pay.
No extra fees. No unexpected letters.
Be careful with “unknown” webshops
I regularly see the exact same display sold on lesser-known websites for prices between €6 and €12. Often with polished marketing, but in practice:
— returns are usually not free
— customer support is hard to reach
— specifications are not always accurate
On AliExpress, returns are often free. My advice is simple: never pay more than the price shown on

What can you use this display for?
— beginner Arduino projects
— ESP32 dashboards and interfaces
— temperature and weather stations
— clocks and timers
— relay and power supply status indicators
— compact projects with limited GPIO availability
Because it uses an HD44780-compatible controller, software support is broad and stable. Libraries like LiquidCrystal_I2C work out of the box.

Frequently asked questions (FAQ)
Is this display suitable for beginners?
Yes. Thanks to I2C, it’s one of the easiest displays to start with.
Do I need to solder anything?
Usually not. The I2C adapter is often already soldered on. Check when it arrives.
Does it work with ESP32?
Yes, as long as you configure the correct SDA/SCL pins and I2C address.
Is the operating voltage 5V?
Yes, standard operating voltage is 5V.
Are there any extra costs after ordering?
No. The price shown on
https://s.click.aliexpress.com/e/_c2zffIFh
includes VAT and is handled upfront.
