The LCD2002 20×2 Character LCD Display (Blue Backlight) is a HD44780-compatible alphanumeric screen that shows 20 characters across 2 lines, offering more horizontal space than a standard 16×2 module for longer labels and readings. It uses a blue background with crisp white text for clear visibility in typical indoor lighting.
Key features:
- 20×2 Character Display: Shows two lines of 20 characters each, useful for longer labels, units, or multi-value readouts.
- HD44780-Compatible Controller: Works with the widely supported HD44780 command set and standard Arduino LCD libraries.
- Blue Backlight: High-contrast white-on-blue display for clear visibility in normal lighting.
- Parallel Interface: Connects via an 8-bit or 4-bit parallel interface using the standard 16-pin header.
- I2C Adapter Compatible: Can be paired with a separate I2C backpack to cut down the pin count needed from a microcontroller.
- Wide Operating Voltage: Runs on a standard 5V supply, compatible with Arduino and similar 5V logic boards.
Its wider single-line format suits readouts with longer text than a 16-column display can comfortably show.
