The 1602 LCD Display 16x2 with blue backlight operates at 5 V and is designed for low-power, handheld projects. Compatible with Arduino and the I2C interface module for easy 2-wire connection. Displays up to 32 characters across two rows.

 

The 1602 LCD Display 16x2 with Blue Backlight (MPN: 1602) is a classic character LCD module capable of displaying 16 characters across 2 rows — 32 characters in total. Running at a standard 5 V logic level, it is purpose-built for low-power embedded applications such as handheld devices, sensor readouts, and DIY electronics projects. It is fully compatible with the optional LCD I2C Interface Module, which reduces the wiring from 6+ data lines down to just 2 (SDA/SCL).

Key Features

  • 16×2 Character Display: Shows up to 32 alphanumeric characters — ideal for status messages, sensor values, and menus.
  • Blue Backlight: High-contrast blue/white backlight ensures readability in low-light environments → great for indoor and enclosure-mounted projects.
  • 5 V Operation: Standard 5 V logic makes it directly compatible with Arduino UNO, Nano, and Mega without any level shifting → plug-and-play simplicity.
  • Low Supply Current (1.5 mA): Extremely low logic supply current means minimal drain on your microcontroller's power rail → suitable for battery-powered builds.
  • I2C Module Compatible: Works seamlessly with the I2C backpack adapter (sold separately) → reduces GPIO usage to just 2 pins.
  • Wide Input Voltage Range (4.5 V–5.5 V): Tolerates slight voltage variations from regulated supplies → robust in real-world wiring scenarios.

Compatibility

  • Arduino UNO / Nano / Mega: Direct 5 V compatibility — no level shifter needed. Can be driven via parallel interface (4-bit or 8-bit mode) or via the optional I2C backpack module.
  • Raspberry Pi / ESP32 (3.3 V systems): Requires a logic level converter or the I2C backpack with voltage regulation when used with 3.3 V platforms.

Typical Applications

  • Displaying real-time sensor data (temperature, humidity, distance) in Arduino projects
  • Menu navigation interfaces for DIY devices and enclosures
  • Clock and timer displays in embedded systems
  • Status readouts for home automation controllers
  • Educational electronics kits and university lab exercises

FAQ

Q: Do I need the I2C module to use this LCD with Arduino?
A: No — the LCD works in standard parallel mode directly with Arduino. However, adding the I2C backpack (LCD120, sold separately) reduces the required pins from 6 to just 2, which is ideal when GPIO pins are scarce.

Q: Can I use this display with an ESP32 or Raspberry Pi?
A: The display operates at 5 V logic. For 3.3 V platforms like ESP32 or Raspberry Pi, a logic level converter is recommended to avoid damaging the microcontroller's GPIO pins.

Package Contents: 1 × LCD Display 16x2 Blue Backlight (1602)
⚠ Note: The I2C interface module is not included and is sold separately (see LCD120). Ensure backlight current (120 mA) is supplied from an adequate power source and not directly from a microcontroller GPIO pin.
