Product details of IIC/I2C Serial Interface Adapter LCD Module PCF8574
This is another great IIC/I2C Serial Interface. 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 realize 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.
2x16 Character LCD is most popular display component for small controller like Arduino, but most of these LCD uses parallel interface. In most of the case, you will need 10 pins to control it or to display message on it. 8-pin are for the data, Enable and Latch pin for signal control. Minimum, you will need 6-pin for 4-bit mode interface. Still a lot of pins being used up :(
This I2C module for LCD will help you save all those precious pins. This module will only need 2 GPIO pins (specifically I2C pins) to send message to Character LCD.
Specification of IIC/I2C Serial Interface Adapter LCD Module PCF8574
Supply voltage: 5V
I2C Address: 0X20~0X27 (the original address is 0X27,you can change it yourself)
the backlight and contrast is adjusted by potentiometer
Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
