This is IIC/I2C Serial Interface Adapter Module. This is a RoHS compliant I2C Serial LCD Daughter board that can be connected to a standard 16x2 or 20x4 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode, and nearly all commercially available 16x2 and 20x4 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 it's own address)

Specifications and Features:

  1. 5V power supply.
  2. Serial I2C control of LCD display using PCF8574.
  3. Backlight can be enabled or disabled via a jumper on the board.
  4. Contrast control via a potentiometer.
  5. Can have 8 modules on a single I2C bus (change address via solder jumpers)address, allowing.
  6. Size :41.6 x 19.2 mm.

Package Includes:

1 x IIC/I2C Serial Interface Adapter Module

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
