The LCD Keypad Shield LCD1602 compatible with Arduino is an essential accessory for developers and electronics enthusiasts using Arduino or Freeduino boards. This shield combines a 2-row by 16-character LCD display with six momentary buttons, making direct and visual interaction with your projects easier.

This module uses pins 4, 5, 6, 7, 8, 9 and 10 for the LCD interface, while analogue pin 0 is used for reading the buttons. This allows efficient control without the need for multiple additional connections.

Main features:

Operating voltage: 5V, compatible with most Arduino boards.
2x16 character LCD display for showing text and relevant information.
Six integrated momentary buttons for easier navigation and control.
Support for contrast adjustment and a backlight function that can be switched on or off as needed.
Analogue pin expansion, allowing simple reading of analogue sensors and direct display on the screen.

This shield is ideal for projects that require a simple, visual user interface, such as interactive menus, device control or real-time data display. Its plug-and-play design allows quick and hassle-free integration with Arduino and Freeduino boards.

Documentation and available resources:

With this shield, interaction with your Arduino projects becomes more intuitive and professional, making it easier to develop applications with simple graphical interfaces and integrated controls.

5V operating voltage compatible with Arduino and Freeduino.
2x16 character LCD display for clear, easy-to-read text.
6 integrated momentary buttons for quick and easy control.
Support for contrast adjustment and switchable backlight.
Analogue pin expansion for reading and displaying sensors.

Customer Questions & Answers

What are the materials, dimensions and weight of the shield, and what exactly is included in the box?

The shield is built from FR4 fibreglass PCB, standard electronic components and an LCD module with a compatible HD44780 controller. Typical dimensions are 80 mm x 58 mm x 23 mm, and the weight is around 42 g. The package generally includes only the assembled shield, without cables or printed documentation; it is advisable to check whether the seller adds a manual or extra accessories.

What are the operating limits of the LCD (voltage, current, environmental conditions), and are there risks if these are exceeded?

The LCD and shield are designed to operate at 5 V±0.25 V, with typical consumption below 50 mA with the backlight on. They operate reliably between 0 °C and 50 °C and RH < 80% (non-condensing). Voltages above 5.5 V can irreversibly damage the controller or the LED backlight, so regulated power supplies should always be used.

How is the contrast adjusted and the backlight managed, and is periodic maintenance required?

Contrast is adjusted using a potentiometer on the shield itself, allowing it to be adapted to different viewing angles or lighting conditions. The backlight can be switched on/off programmatically or via a jumper, depending on the version. No periodic maintenance is required; however, it is recommended to avoid damp or excessively dusty environments and to clean the screen gently if needed.

Which boards is the LCD Keypad Shield LCD1602 compatible with?

It is compatible with Arduino and Freeduino boards that support a 5V operating voltage.

How many buttons does this shield include and what are they for?

It includes 6 momentary buttons that allow you to control menus and functions directly from the shield.

Can I adjust the display contrast and backlight?

Yes, the shield supports contrast adjustment and allows the backlight to be switched on or off as needed.

Which pins does it use for connection to Arduino?

It uses digital pins 4, 5, 6, 7, 8, 9 and 10 for the display and analogue pin 0 for button reading.

Are there resources and documentation to help with use?

Yes, links to manuals, libraries and schematics are included to make integration and programming of the shield easier.
