Features:
Apply to:
With the help of the LCD module, you can display most things through the programming code that compatible with Arduino and Raspberry pi.

Practical to use:
LCD display with I2C serial interface has 2 bidirectional data lines, a serial data line and a serial clock. Through the IIC/I2C interface, it only occupies two I/O ports, thus saving more space for other uses.

With backlight
You can adjust the contrast through the contrast on the back of the potentiometer. If you don’t want to use the backlight, you can also unplug the jumper cap on the back of the LCD. Through the backlight power control, it can be set to the backlight power through a jumper connection. Insert the jumper to turn off the backlight, and remove the jumper to disconnect it.

Line output is simple:
The contrast can be adjusted by turning the blue potentiometer clockwise and decreasing the blue potentiometer counterclockwise. The potentiometer is designed on the front, so your can adjust it at any time.

Compatibility: LCD display module is compatible with Arduino and Raspberry pi; It’s working voltage is 5V and equipped with potentiometer to adjust backlight and contrast
Easy to work: small I2C interface module can work very well; It only needs 2 signal connections, each of which requires a power supply and ground wire; A good circuit can reduce the number of connections between MCU and LCD; The 1602 LCD, each line displays 16 characters, a total of 2 lines, parallel interface, small in size, low power consumption and easy display operation
IIC interface adapter: support IIC protocol, the kit contains an IIC / I2C serial interface adapter, no need to purchase an additional adapter, only two I/O ports, saving more space for other purposes, so you can call it directly
Wide applications: LCD display with I2C serial interface can be applied to display characters, letters and numbers, real-time clocks, temperature, humidity, suitable for copiers, fax machines, industrial testing equipment, and network equipment such as routers and storage devices
