Specification

Description

16x2 LCD I2C IIC TWI SPI Serial Interface Adapter

This is the IIC/I2C Serial Interface Adapter Module.
This is a RoHS-compliant I2C Serial LCD Daughter board that can be connected to a standard 16×2 or 20×4 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode, and nearly all commercially available 16×2 and 20×4 line character modules support it too.

This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. There are many examples on the internet for using this board with Arduino. Do a search for “Arduino LCD PCF8574“. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. This allows up to 3 LCD displays to be controlled via a single I2C bus (giving each one its address)

Technical Details

  • Model Type: IIC/I2C Module
  • IC Chip: PCF8574
  • Input Voltage: 5VDC
  • PCB Size: 42mm x 20mm
  • Weight: 4g

Features

  • 5V power supply
  • Serial I2C control of LCD using PCF8574
  • Backlight can be enabled/disabled via jumper on board
  • Contrast control via potentiometer
  • Supports up to 8 modules on a single I2C bus (address change via solder jumpers)
  • Size: 41.6mm x 19.2mm

Applications :

  • Displaying information in embedded systems projects
  • Real-time data output for Arduino, Raspberry Pi, and microcontroller projects
  • Simple user interfaces for electronics projects
  • Digital clocks and timers
  • Temperature, humidity, and sensor data display
  • System status monitoring and feedback
  • Control panels for automation systems
  • Vehicle or robot status display
