1602 LCD Display/ 16x2 Characters LCD...

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 OverviewThe 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 CustomersHigh 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 GuideTo get your display running from www.electrapac.com, follow this standard pin configuration:VSS / VDD: Ground and 5V Power.VO: Contrast adjustment (Connect to the middle pin of a 10k potentiometer).RS / RW / E: Control pins for data instruction and execution.D0-D7: 8-bit Data pins (Most projects use 4-bit mode using only D4-D7 to save pins).A / K: Backlight Anode ( ) and Cathode (-).Primary ApplicationsEnvironmental 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.Why Shop at Electrapac?We ensure our 1602 LCDs are sourced with high-quality headers and uniform backlighting to prevent "dark spots" on your display.
