LCD1602 Yellow Green Backlight 5V With IIC

This is a 16×2 LCD display screen with I2C interface. It is able to display 16×2 characters on 2 lines, black characters on yellow-green backlight. It also includes a serial I2C/IIC adapter board pre-soldered to the back of the LCD. This means it can be controlled with just 2 I2C serial data pins (SDA & SCL) and so requires far less digital IO pins when controlled from a microcontroller. In total the module only requires 4 wires including 5V power and GND. Contrast adjustment is also provided by the daughter board via a potentiometer. It is highly used for DIY Ardu based project.
