Description

Description

The standard HD44780 displays are really useful for creating standalone projects.
They can easily interface with many platforms such as Arduino.
We offer here a white 20x4 LCD screen on a blue background accompanied by an LCD controller I2C (a backpack). 

The I2C backpack makes it easy to control an LCD screen using only two Arduino pins (A4 and A5 of the I2C bus). This is a very appreciable tool given the very limited pin number on an Arduino Uno. If you have already connected several sensors on your Arduino, you will not have enough pins to control an LCD screen... this I2C breakout will be your savior.  

What's great about the I2C bus, is that you can have other I2C peripherals on the same bus (without consuming more pins). You can even use multiple LCD screens on the same Arduino because this breakout has address pins (to change the address of the breakout on the I2C bus). 

Using an I2C LCD screen is an excellent Arduino project, a good introduction to I2C and a useful tool for future projects. 

Thanks to the Arduino LiquidCrystal_I2C library, taking control of this screen is really child's play (see Tutorial section). The library supports the I2C 1602 interface. Tested and approved by MC Hobby.

You will, however, need to take out your welding iron to weld the backpack (I2C controller) on the LCD screen. 

Technical details of the backpack

  • Interface: I2C
  • I2C Address: 0x27 (default)
  • Pin Identification, Pin: VCC、GND、SDA、SCL
  • HD44780 controller-based 16-pin LCD screen (same as 2-lines screen white/blue or 4-lines screen)
  • Backlight
  • Supply voltage: 5V
  • Size: 27.7mm×42.6mm
  • Contrast adjustment: with potentiometer
  • Uses only two input/output.
  • Also works with 20x4 white/blue screens.

Technical details of the LCD

  • 4 lines of 20 characters each 
  • Text in White, Blue background 
  • Connector with impaction of 2.54mm, so it can fit into a breadboard (with the use of a pin-Header)
  • The pins are noted on the back of the LCD display. This really facilitates the wiring.
  • Can be totally controlled using 6 digital pins! (any analog/digital pin of your Arduino can be used). 
  • Contains the "character set" for rendering English/Japanese texts, see the data sheet of the HD44780 for all available "character sets".
  • Has 8 extra characters to easily create Glyphs (mini-images), symbols or international characters.
