Description

  • DFRobot I2C/TWI LCD1602 Module
  • Features clear 16x2 LCD with blue backlight
  • Utilizes I2C for simple wiring in Arduino
  • Provides adjustable contrast for clarity
  • Offers configurable I2C address to prevent conflicts
  • Includes breadboard-friendly XH2.54 connectors

The DFRobot I2C/TWI LCD1602 Module is a 16x2 character LCD display designed for use with Arduino projects. It features a blue background with white characters, offering a clear and visually appealing display. This module is particularly advantageous for projects where pin availability is limited, such as those using the Arduino Uno, as it employs an I2C communication interface. This interface requires only four pins for connection, namely VCC, GND, SDA, and SCL, thereby simplifying the wiring and reducing the complexity of connections.

The module is equipped with standard XH2.54 connectors, which are compatible with breadboards and allow for straightforward connections using jumper wires. This feature enhances the ease of installation and provides flexibility in project design. The I2C address of the module is configurable within the range of 0x20 to 0x27, allowing users to avoid address conflicts with other I2C devices such as ultrasonic sensors and accelerometers. Additionally, the contrast of the display can be manually adjusted using a potentiometer, enabling optimization of the display's visibility according to environmental conditions and personal preferences.

For projects requiring more display space, an alternative option is available in the form of a 20x4 character LCD display module, which offers a larger display area. This alternative can accommodate more characters, providing additional space for information presentation.

Note: Ensure proper handling of the module to avoid damage to the display or connectors.

excellent had not problems

worked with numerous libraries. just need to find the address when using with arduino. use i2c scanner code below for finding the address. // -------------------------------------- // i2c_scanner // // Version 1 // This program (or code that looks like it) // can be found in many places. // For example on the Arduino.cc forum. // The original author is not know. // Version 2, Juni 2012, Using Arduino 1.0.1 // Adapted to be as simple as possible by Arduino.cc user Krodal // Version 3, Feb 26 2013 // V3 by louarnold // Version 4, March 3, 2013, Using Arduino 1.0.3 // by Arduino.cc user Krodal. // Changes by louarnold removed. // Scanning addresses changed from 0...127 to 1...119, // according to the i2c scanner by Nick Gammon // http://www.gammon.com.au/forum/?id=10896 // Version 5, March 28, 2013 // As version 4, but address scans now to 127. // A sensor seems to use address 120. // Version 6, November 27, 2015. // Added waiting for the Leonardo serial communication. // // // This sketch tests the standard 7-bit addresses // Devices with higher bit address might not be seen properly. // #include void setup() { Wire.begin(); Serial.begin(9600); while (!Serial); // Leonardo: wait for serial monitor Serial.println("\nI2C Scanner"); } void loop() { byte error, address; int nDevices; Serial.println("Scanning..."); nDevices = 0; for(address = 1; address < 127; address++ ) { // The i2c_scanner uses the return value of // the Write.endTransmisstion to see if // a device did acknowledge to the address. Wire.beginTransmission(address); error = Wire.endTransmission(); if (error == 0) { Serial.print("I2C device found at address 0x"); if (address<16) Serial.print("0"); Serial.print(address,HEX); Serial.println(" !"); nDevices++; } else if (error==4) { Serial.print("Unknown error at address 0x"); if (address<16) Serial.print("0"); Serial.println(address,HEX); } } if (nDevices == 0) Serial.println("No I2C devices found\n"); else Serial.println("done\n"); delay(5000); // wait 5 seconds for next scan }

Solid built board, but not well supported (yet)

Had issues locating a library that actually worked, could not get the standard libraries to work but I did eventually locate a library that does work and appears to perform well.

Panneau solide, mais pas encore pris en charge

Des problèmes pour localiser une bibliothèque qui fonctionnait réellement ne pouvaient pas faire fonctionner les bibliothèques standard, mais j’ai fini par trouver une bibliothèque qui fonctionne et semble bien fonctionner.
