Blue Backlit LCD 1602 — 16x2 Character Display Module with Blue and Yellow Green Backlight 2 lines × 16 characters, screen size 80 × 36 mm (measures 3.14 × 1.41 in) Operates on 5V power supply Adjustable contrast via onboard potentiometer Plastic surface construction for durable, lightweight mounting I2C (IIC) protocol interface reduces wiring and saves microcontroller I/O Why you need it Simplifies wiring: I2C connection requires only four pins (VCC, GND, SDA, SCL), freeing up I/O for sensors, actuators, or other peripherals. Quick integration: Builtin I2C interface library lets you connect to Arduino and Raspberry Pi projects immediately and simplifies code setup. Reliable in real applications: Stable I2C communication and adjustable contrast/backlight controls make it suitable for continuous use in hobby or industrial environments. Key benefits and what makes it stand out Simple control: Directly adjust backlight and contrast from hardware and software for clear readability in varied lighting. Compact but readable: 16×2 character layout on an 80×36 mm display fits tight enclosures while presenting essential information. Versatile backlighting: Blue and yellowgreen backlight options improve visibility and match project aesthetics or requirements. Compatible with common development boards: Ready for Arduino and Raspberry Pi compatible projects without complex wiring changes. Compatibility and performance Power: 5V supply Interface: I2C (VCC, GND, SDA, SCL) Construction: Plastic surfaces designed for continuous operation in DIY and light industrial setups Size: Screen 80×36 mm; overall module approximately 3.14×1.41 in Practical applications (examples) Arduino sensor display: Show temperature, humidity, or sensor readouts while keeping most Arduino pins for additional modules. Raspberry Pi status panel: Display system status, IP address, or simple menus without complex wiring or GPIO usage. Industrial or workshop controllers: Present machine states, setpoints, or error messages in a compact enclosure with adjustable contrast and backlight for clear visibility. What's included / ready to use 16×2 LCD module with blue and yellowgreen backlight Builtin I2C interface and supporting library for immediate use with Arduino and Raspberry Pi, enabling quick code integration and direct control of backlight and contrast Specifications summary Display: 2 lines × 16 characters Screen size: 80 × 36 mm Module size: 3.14 × 1.41 in Voltage: 5V Interface: I2C (VCC, GND, SDA, SCL) Contrast: Adjustable by potentiometer Construction: Plastic surface Reliable, compact, and easy to integrate — ideal for Arduino and Raspberry Pi projects that need a clear character display with minimal wiring and flexible backlight/contrast control.
