Features

  • 1.The I2C interface is a huge improvement, freeing up a lot of pins on the Arduino for additional functionality. Works fine with the LCD1602 and LCD2004.
  • Modules can be cascaded up to eight. The device address can be modified by short-circuiting A0/A1/A2. The default address is 0x27. The default address can be detected by the program.
  • The module uses the PCF8574, which enables most MCUs to implement remote I/O port expansion via two bidirectional buses (I2C). The device includes an 8-bit quasi-bidirectional port and an I2C bus interface.
  • The contrast is adjustable, and the blue potentiometer is rotated clockwise to enhance, and counterclockwise to weaken.With backlight power control, you can set whether to connect the backlight power through the jumper cap.
  • The original LCD1602/2004 screen requires 7 IO ports to drive. This module only needs 2 IO ports to drive, which can save you 5 IO ports.

Description

As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project. Specifications: Input Voltage: DC2.5-6V Protocol: IIC (I2C) With backlight Adjustable contrast PCB Board Color: black Weight: 5g Size: 41.5 mm×19 mm×15.3 mm/ 1.63″×0.75″×0.60″ Device Address:0x20~0x27 The device address can be modified by short-circuiting A0/A1/A2. The default address is 0x27. The default address can be detected by the program.

  • Muy buena calidad
Funcionan muy bien! Recomendado

  • Really simplifies the connection of the LCD to an Arduino board.
Many good libraries out there to make connecting the LCD via I2C simple. There is a little learning curve, but with all the good examples that are included with most libraries is has been a great experience.

  • Makes character displays easy to interface
I have already used two of these that I purchased earlier on two other projects. I have a water valve control project that will need at least one more display but I ordered the five pack so I would have extras. I am always needing a debug display of some kind usually on the fly during project development. Any way, these are great, Just load and initialize the liquidCrystaiI2c library and you are set to go. ... show more
