This is an 16×2 LCD display screen with I2C interface. It is able to display 16×2 characters on 2 lines, white characters on blue background. Usually, Arduino LCD display projects will run out of pin resources easily, especially with Arduino Uno. And it is also very complicated with the wire soldering and connection. This I2C 16×2 Arduino LCD Screen is using an I2C communication interface. It means it only needs 4 pins for the LCD display: VCC, GND, SDA, SCL. It will saves at least 4 digital / analog pins on Arduino. All connector are standard XH2.54 (Breadboard type). You can connect with jumper wire directly. To avoid the confliction of I2C address with other I2C devices, such ultrasonic sensor, IMU, accelerometers and gyroscope, the I2C address of the module is configurable from 0x20-0x27. And its contrast can be adjusted manually. Another alternative option is I2C 20×4 Arduino LCD Display Module if more characters is required. Last update: V1.2: I2C connector: VCC, GND, SCL, SDA SPECIFICATION Compatible with Arduino/Genuino UNO, Leonardo, Mega, 101 (Intel Curie), Micro, Nano, Mini I2C Address:0x20-0x27(0x20 default) Back lit (Blue with white char color) Supply voltage: 5V Interface:I2C/TWI x1,Gadgeteer interface x2 Adjustable contrast Size: 80x36x20mmz(3.1×1.4×0.7in)
