Product Description
The 1602 LCD Module is a robust and reliable display solution. It uses the industry-standard HD44780 controller, which means it is compatible with almost every microcontroller library available today. The module includes a built-in LED backlight and a command set that allows you to clear the screen, move the cursor, and even create custom characters (like battery icons or degree symbols). It features a standard 16-pin header for easy connection via jumper wires or for soldering directly to a PCB.
Key Features
High Readability: White characters on a blue background provide excellent clarity, especially in indoor environments.
Low Power Mode: The backlight can be turned off via the "K" and "A" pins to reduce current consumption to just a few milliamps.
Standard Interface: Works in both 8-bit mode (for speed) or 4-bit mode (to save 4 GPIO pins on your microcontroller).
Adjustable Contrast: Using an external 10k potentiometer, you can fine-tune the pixel darkness to suit your viewing angle.
Extensive Library Support: Fully supported by the standard LiquidCrystal library in the Arduino IDE.
