The 1602 LCD Display (16x2 Characters Blue Backlight) is the industry standard for adding a visual interface to your electronics projects. At Electrapac, we recommend this module for anyone needing to display sensor data, system status, or custom messages in real-time with high clarity and low power consumption.

Product Overview

The 1602 LCD can display 16 characters per line across 2 lines, for a total of 32 characters. It features a high-contrast blue background with white text, making it easily readable even in low-light conditions. It is powered by the built-in HD44780 controller, which is supported by nearly every microcontroller library.

Key Features for Electrapac Customers

• High Contrast & Sharpness: The white-on-blue design provides excellent visibility. The contrast can be finely tuned using a simple 10k potentiometer.

• Low Power Consumption: Operates on a standard 5V supply, drawing very little current—perfect for battery-powered Arduino or Raspberry Pi projects.

• Extensive Library Support: Since it uses the HD44780 driver, it works out-of-the-box with the standard LiquidCrystal library in the Arduino IDE.

• Custom Character Support: You aren't limited to standard letters and numbers; you can program the module to display custom icons like battery levels, heart symbols, or progress bars.

• Adjustable Brightness: The LED backlight can be controlled via the onboard pins or through a PWM signal for energy saving.

Pinout & Connection Guide

To get your display running from www.electrapac.com, follow this standard pin configuration:

1. VSS / VDD: Ground and +5V Power.

2. VO: Contrast adjustment (Connect to the middle pin of a 10k potentiometer).

3. RS / RW / E: Control pins for data instruction and execution.

4. D0-D7: 8-bit Data pins (Most projects use 4-bit mode using only D4-D7 to save pins).

5. A / K: Backlight Anode (+) and Cathode (-).

Primary Applications

• Environmental Monitors: Display temperature, humidity, and air quality from sensors like the DHT11 or BME280.

• Industrial Counters: Real-time piece counting or RPM displays for machinery.

• Home Automation: Displaying "Door Locked," "Lights On," or current time/date.

• DIY Test Gear: Build your own digital voltmeter, ammeter, or frequency counter.
