16×2 display 1602 has the I2C backpack module mounted on the back side, which requires only two connected wires for data and two wires to supply ground and 5V to power the display. The I2C backpack also allows you to change the I2C address of the module, Typically this unit has 16 pin outs that requires a breadboard to interface with any microcontroller and a 10k potentiometer to adjust the contrast value to reduce the backlight and view the text. However, with the addition of the I2C Backpack pre-soldered, you only need to connect four pins to your microcontroller. You do not need to worry about the 16 pin cables that need to be connected, and the unit comes with a potentiometer to adjust the Contrast. You also have a jumper for two pins to enable or disable brightness.16×2 display Specification :Operating Voltage: 5vBackground color: GREENText Color: WhiteI2C Address: 0x3FRows: 2Columns: 16Package Included:1 x 16*2 I2C Green LCD
