LCD1602 I2C Display Module 2x16 Characters 5V for Arduino
LCD1602 Display Module with I2C Interface & Backlight – 2×16 Characters, 5V
Upgrade your microcontroller projects with this versatile LCD1602 Display Module. Featuring a crisp 2-line × 16-character display with an adjustable backlight, this module integrates seamlessly with Arduino, Raspberry Pi, and compatible boards via a convenient I2C serial interface — drastically reducing the number of wiring pins required.
Key Features
- 2×16 Character Display: Green/blue backlit LCD screen capable of showing 2 lines of up to 16 characters each — perfect for text, numbers, real-time clock readouts, temperature, humidity, and more.
- I2C Serial Interface Backpack: Built-in I2C adapter (PCF8574T or PCF8574AT chip) simplifies wiring to just 4 pins: GND → GND, VCC → VCC, SDA → A4, SCL → A5.
- Default I2C Addresses: 0x27 for PCF8574T chip; 0x3F for PCF8574AT chip. Check your chip before uploading code. (Download the I2C library from GitHub before use.)
- Wide Compatibility: Works with Arduino Duemilanove, UNO R3, MEGA, and Raspberry Pi. Operating voltage: 5V DC.
- Adjustable Contrast & Backlight: Onboard potentiometer lets you fine-tune both contrast and backlight brightness for optimal readability in any environment.
- Versatile Applications: Display real-time clocks, temperature sensors, humidity readings, custom messages, menus, and alphanumeric data in your DIY electronics projects.
