16x2 Character LCD Display Module

Add a clear, low-cost user interface to your electronics project with this 16x2 Character LCD Display Module. A 16x2 LCD can display 32 alphanumeric characters at a time, arranged as 16 columns and 2 rows, making it one of the most popular displays for Arduino projects, embedded systems and educational kits in India. It is commonly used to show live sensor values, menu options, device status, password prompts, battery voltage, temperature, time, count values and diagnostic messages. The module is based on the widely supported HD44780-compatible LCD controller architecture, so it works with standard LCD libraries available for Arduino IDE, AVR, PIC, STM32 and many other microcontrollers. It can be operated in 8-bit mode for full parallel control or 4-bit mode to save microcontroller pins. A contrast input pin allows adjustment using a 10k potentiometer, while the LED backlight pins make the display readable in indoor and low-light environments. The standard 16-pin header layout includes power, contrast, register select, read/write, enable, data lines D0-D7 and backlight connections. This character LCD module is an excellent choice for lab instruments, automation panels, robotics dashboards, attendance systems, weighing scales, battery monitors, digital clocks, IoT status units and student mini-projects. It is easier to program than a graphical display and gives a professional front-panel look without increasing project cost. For I2C-based wiring, it can also be paired with a compatible PCF8574 I2C LCD backpack module, reducing connections to just VCC, GND, SDA and SCL. In the box: 1 x 16x2 Character LCD Display Module. Header pins may be pre-soldered or supplied separately depending on stock batch. For best results, use a regulated 5V supply, set the contrast correctly, and verify backlight polarity before powering the module.
