2X16 LCD Display Blue 5V

A 2×16 character LCD display with blue backlight and white characters — the most widely used display in all of electronics education and prototyping. Driven by the HD44780-compatible controller, it works with any Arduino using just 6 GPIO pins (or 2 with an I2C backpack), displaying text, numbers, and custom characters.

🔹 Key Applications

• Sensor data readout display on Arduino projects
• Clock, temperature, and measurement displays
• Menu navigation display for embedded systems
• Status and diagnostic message display
• Educational electronics LCD experiments
• Prototype and bench instrument displays

🔹 Why Choose This Module?

• HD44780-compatible controller — supported by every Arduino LCD library
• Blue backlight with white characters — high contrast readout
• Works directly or with I2C backpack (reduces pins to 2)
• 5 V operation — direct Arduino compatibility
• 2 × 16 characters — enough for most status displays

🔹 Technical Specifications

• Controller: HD44780 compatible
• Characters: 2 rows × 16 columns
• Backlight: Blue LED (white text)
• Interface: Parallel (4-bit or 8-bit) or I2C (with backpack)
• Operating Voltage: 5 V DC

🔹 What's Included

1 × 2×16 Blue Backlight LCD Display

🔹 Pro Tip

💡 Add an I2C LCD backpack (PCF8574-based) to reduce from 6 parallel wires to 2 I2C wires — essential when your project is short on GPIO pins. Use the LiquidCrystal_I2C library for I2C operation. Adjust the contrast trimmer on the backpack for optimal character visibility.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
