White on Blue 16×2 LCD Module with I2C Backpack Module – 5V

Description

This 16×2 character LCD module only uses 2 wire I2C interface. The I2C Interface Board is basically an IO expander board that helps minimize microcontroller / Arduino IO usage pin count. With this module, attached to the back of 16×2 character LCD Module, you can use only two pins (SDA and SCL) to write to LCD module. The typical operating voltage for these display modules is 5.0V.

(The i2c backpack module can also be purchased separately. Please following this link)
