Features: Good function: The LCD with I2C port greatly enriches the human-computer interaction functions, and when they are connected to the controller, the controller without too many external ports will not occupy multiple IOs, and will not restrict other functions of the controller. It has only two bidirectional data lines, a serial data line and a serial clock. Specifications: Display: 2-lines x 16-characters Four Pin Definition: GND, VCC, SDA, SCL Default I2C bus address: 0 x 3F for PCF8574AT chip, 0 x 27 for PCF8574T chip Working voltage: 5V LCD controller: HD44780 Adjust Contrast: Potentiometer Adjust Backlight: Jumper Package includes: 2 x LCD display 2 x I2 C serial interface

1602 LCD display with I2C serial interface is compatible with for Arduino and Raspberry pi, display function: LCD display with I2C serial interface can be applied to display real time clock, temperature, humidity and so on. Application: LCD module is applied to display characters, letters, numbers, real time clock and temperatur. Support IIC protocol. The I2C LCD1602 library is provided, so you can call it directly used to adjust backlight and contrast. Less I/O ports are occupied, only four - VCC, GND, SDA (serial data line), SCL (serial clock line), how to wire: GND—GND; VCC—VCC; SDA—A4; SCL—A5, LCD display module blue with white color. LCD screen can display 2-lines x 16-characters, working voltage: 5V; to come with a potentiometer, which is applied to adjust backlight and contrast.
