I2C LCD Adapter


As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to receive data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based projects. 


  • I2C Address: 0x3F
  • Supply voltage: 5V 
  • The backlight and contrast is adjusted by potentiometer 
  • Comes with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
  • Compatible with 1602 LCD

Dear customer, these "I2C LCD Adapter" have a built-in ADDRESS. If you try to run a display and there is no response or nothing is displayed you may have the wrong address in the code you are using. Please use an address of 0x3F.
Thanks for with us.

Actually the problem was Main chip found TDA1543A instead of PCF8574AT. So funny...

i2c address 0x3F দেয়ার পরও কাজ করছেনা। -_-
ব্যাকলাইট ডিম হয়ে যাচ্ছে আর ফ্ল্যাশ করছে।
এটা কাজ করাবো কিভাবে? :3

গুগলে সার্চ করে আইটুসি স্ক্যানার নামিয়ে নিন। তারপর স্ক্যান করে প্রথমে দেখুন এটার অ্যাড্রেস আসলেই 0x3F কি না ।

A.R | May 7,2018 at 03:35 PM

I2c module which is attached to 20 x 4 lcd, available on your website and this i2c module are basically made of the same chip . Then what is the difference them? You specifically mentioned that it is only for 16 x 2
A.R | Jun 24,2019 at 09:39 AM
No difference. Same thing.

In my case the address was 0x27

But I had to adjust the variable pot on the board to see the texts.
