Buying Guide – How to Choose the Best LCD Character Modules
Selecting the right LCD Character Module involves considering several technical factors to ensure compatibility and performance for your specific project.
Display Size
Display size refers to the number of characters per line and number of lines. Common sizes include 16×2 and 20×4. Larger displays allow for more text but take up more physical space on your board.
Choose a size that fits your enclosure and message requirements.
Interface Type
Interface type determines how you connect the module to your microcontroller. I2C uses fewer wires but parallel requires more. I2C is preferred for projects with limited GPIO pins.
Opt for I2C if you have limited pins or want cleaner wiring.
Backlight Color
Backlight color affects readability and visual style. Blue and white are common for high contrast. Yellow offers a distinct look that reduces eye strain in dark settings.
Select a backlight that matches your lighting conditions and aesthetic.
Controller Compatibility
Controller compatibility ensures the module works with your software library. HD44780 is the industry standard. Newer modules may use compatible chips like PCF8574 for I2C.
Verify the controller before buying to avoid software conflicts.
Power Requirements
Power requirements indicate the voltage needed for operation. Most modules use 5V. Some low power versions exist but are less common. Ensure your power supply matches.
Choose a module that matches your available power source.
Build Quality
Build quality affects durability and lifespan. High quality modules have consistent backlighting and sturdy frames. Cheaper options may have uneven displays or fragile pins.
Prioritize build quality for long-term or production use.
Price and Pack Size
Price and pack size determine value. Buying in bulk reduces cost per unit. Single units are good for testing. Consider your total project needs.
Buy in bulk to save money on larger projects.
How to Use and Care for Your LCD Character Modules
Connect the power pins correctly to avoid damage. VCC connects to 5V and GND to ground. Ensure your power supply is stable and clean.
Install the appropriate library for your microcontroller. For Arduino use LiquidCrystal_I2C. For Raspberry Pi use RPi_LCD. These libraries simplify communication.

Frequently Asked Questions
What voltage do LCD Character Modules require?
Most LCD Character Modules require 5V DC for operation. Some low power variants may use 3.3V but these are less common. Always check the datasheet before connecting power.
Can I connect multiple modules to one board?
Yes you can connect multiple modules using I2C by setting unique addresses. Each module requires a unique address which some support natively. You may need to adjust the address pins if supported.
How do I change the contrast?
Contrast is adjusted using the built-in potentiometer on the back. Turn the screw to increase or decrease contrast. This allows you to find the clearest view.
What are the advantages of I2C over parallel?
I2C uses fewer wires making connections cleaner and easier. It reduces pin usage on your microcontroller. This leaves more room for other components.
Do these work with Raspberry Pi?
Yes these modules are compatible with Raspberry Pi and other boards. You may need a 3.3V to 5V logic level shifter for older models. Most modern boards work directly.
Is there a difference between blue and white backlight?
Blue backlight is more common and offers high contrast. White backlight is newer and looks more modern. Both perform well but white may be harder to find.
