The IIC/I2C INTERFACE FOR 1602 LCD MODULE, such as our TA0170/TA020 require 7 IO pins to be driven from Arduino.
This interface when connected to the 1602 module only requires 2 IO pins, freeing up pins to be used with other modules.
I2C is a serial protocol for a two-wire interface to connect low-speed devices like microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces and other similar peripherals in embedded systems.
The initial I2C specifications defined a maximum clock frequency of 100 kHz.
Package included: 1x IIC/I2C INTERFACE FOR 1602 LCD MODULE NOTE (LCD screen not included)

This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of the Arduino controller is limited, your project may be not able to use a normal LCD shield after being 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 have I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based projects.
