Introduction

Referring to the LCD16020, I believe that everyone is not unfamiliar the square shape, green color, a row of 2.54 pin header.... LCD1602 module is a product of the DFRobot Gravity IIC series, which has been greatly optimized for its original LCD1602 appearance. This module does not need to adjust the contrast, retain the backlight controllable function, simultaneously compatible with 3.3V and 5V voltage. The optimization of function and the appearance brings you the different experience. This kind of module has the blue screen, the green screen, the gray screen.
