QZ005 LCD 1602 I2C Module

1.Product Introduction

LCD (Liquid Crystal Display) is a passive display, that is, the liquid crystal itself does not emit light, it needs a backlight to provide background brightness, the use of electric fields to control the arrangement of liquid crystal molecules, so as to change the transmission of light and block, to achieve image display.

LCD 1602 I2C Module As the name suggests, this module is a 16 character x2 line LCD display module (can display 32 ASCII characters), and with an I2C communication interface module, the default I2C address 0x27, with a blue potentiometer on the back. Can be used to adjust the backlight (when the character display is not clear, you need to adjust the backlight to make the character display clearly).

Application reference: This module can be used for data display of control panel, electronic scale, electronic clock, etc.
