I2C PCF8574T PCF8574AT Board Module Arduino 1602 2004 LCD Display

Specification:

This is another great IIC/I2C/TWI/ 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. It is fantastic for Arduino based project.

• PCF8574T I2C Address: 0X20~0X27 (the original address is 0X20,you can change it yourself)
• PCF8574AT I2C Address: 0X38~0X3F (the original address is 0X38,you can change it yourself)
• Supply voltage: 5V
• the backlight and contrast is adjusted by potentiometer
• Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
• Compatible for 1602 LCD 2004 LCD
