DESCRIPTION

🔶 IIC I²C Serial Interface Board Module – LCD1602 Display Adapter for Arduino / PIC / Raspberry Pi

📦 Overview

This compact IIC/I²C serial interface board enables a classic LCD1602 (16×2) character display to be connected with just two wires (SDA/SCL), significantly reducing wiring complexity compared to standard parallel LCD connections. Compatible with microcontrollers including Arduino, PIC, Raspberry Pi, ARM and many other I²C hosts. Ideal for adding informative text displays to your embedded projects with minimal

✅ Key Benefits

Converts standard LCD1602 parallel interface to I²C (SDA/SCL)
Saves many GPIO pins on microcontrollers
Simple 4-pin connection: VCC, GND, SDA, SCL
Compatible with Arduino, Raspberry Pi, PIC and ARM boards
Adjustable LCD contrast via onboard potentiometer

🔌 Wiring Guide (I²C)

LCD  
----  
VCC   --> 5V  
GND   --> GND  
SDA   --> SDA pin (e.g. A4 on Arduino Uno, GPIO2 on ESP32/ESP8266)  
SCL   --> SCL pin (e.g. A5 on Arduino Uno, GPIO22 on ESP32)

The I²C address is often 0x27 or 0x3F — use an I²C scanner sketch to detect the correct address for your setup.

🧩 Arduino Example (I²C LCD)

Click to expand — Arduino I²C LCD code

#include 
#include 

LiquidCrystal_I2C lcd(0x27, 16, 2); // Change address if needed

void setup() {
  lcd.init();  
  lcd.backlight();
  lcd.setCursor(0, 0);
  lcd.print("Hello, World!");
  lcd.setCursor(0, 1);
  lcd.print("I2C LCD1602");
}

void loop() {
  // Example: scroll text
  lcd.scrollDisplayLeft();
  delay(300);
}

🐍 Raspberry Pi I2C LCD Example

Click to expand — Python (smbus) I²C LCD code

import smbus
import time

# Import an HD44780/I2C LCD library for Pi (e.g., Adafruit_CharLCD or custom)

# Example uses smbus and an LCD library to write text:
from RPLCD.i2c import CharLCD

lcd = CharLCD('PCF8574', 0x27)  # Change address if needed
lcd.write_string("Pi I2C LCD!")
time.sleep(2)
lcd.clear()
lcd.write_string("I2C 16x2 Display")

💡 Possible Uses

Character LCD interface with minimal wiring
Arduino status displays (sensor readings, menus)
Raspberry Pi I²C LCD projects (GPIO saving)
PIC / ARM microcontroller learning projects
DIY embedded UI and diagnostics display
