16×2 LCD Display with I2C – Pre-Soldered Module for Arduino

16×2 LCD Display with I2C – Pre-Soldered Character Display

The 16×2 LCD Display with I2C is a character display module designed for electronics projects that need to show text, readings, status messages and other information. It features a 16-column by 2-row LCD screen and a pre-soldered I2C interface, helping simplify connections to compatible microcontrollers.

Instead of requiring multiple parallel data connections, the I2C interface allows communication through two signal lines, alongside power and ground. This reduces the number of controller pins needed for the display and makes wiring more manageable in Arduino, Raspberry Pi and ESP32 projects.

The pre-soldered module is convenient for students, electronics enthusiasts, makers and developers who want to add a text display without soldering the interface module themselves.

Key Features of the 16×2 LCD Display with I2C

• 16×2 character display: Shows up to 16 characters per row across two rows.

• Pre-soldered I2C module: The interface is already attached, reducing assembly work.

• Four-wire connection: Uses power, ground, SDA and SCL for the I2C connection.

• Reduced GPIO usage: Requires fewer microcontroller pins than a typical parallel LCD connection.

• Compatible project platforms: Suitable for compatible Arduino, Raspberry Pi and ESP32 setups.

• Clear character display: Presents text and numerical information for monitoring and control projects.

• No interface soldering required: Helps beginners get started more easily.

16 Columns and 2 Rows for Project Information

The display provides two rows, each capable of showing up to 16 characters. This layout is useful for presenting short messages and numerical readings without needing a larger screen.

For example, a project can display temperature on the first row and humidity on the second, show a sensor reading alongside a status message, or present menu options for a small embedded device.

Pre-Soldered I2C Interface

The attached I2C module simplifies the connection between the LCD and a compatible controller. The four main connections are:

The required supply voltage and I2C logic levels depend on the exact module and controller. Confirm these requirements before connecting the display, especially when using a Raspberry Pi or ESP32.

Compatible with Arduino, Raspberry Pi and ESP32

The 16×2 LCD Display with I2C can be used with compatible Arduino boards, Raspberry Pi systems and ESP32 development boards. Software libraries and example code are available for many common development environments.

Compatibility requires suitable wiring, the correct software library and the correct I2C address. The address can vary between interface boards, so it may need to be identified during setup.

Common Applications

This character LCD is suitable for a wide range of electronics and embedded projects.

Technical Specifications

Getting Started

Connect the display’s power, ground, SDA and SCL pins to the appropriate connections on your controller. Load a compatible LCD library, configure the correct I2C address and upload a simple test program to display text.
