NDTC2004001 | Character Display 20x4 LCD with Arduino 2004 LCD i2c STN LCD Yellow Green
The 2004A LCD display is a high-capacity 20×4 character module, offering 4 lines with 20 characters each for applications requiring expanded text output. Built with STN-LCD Yellow Green technology and a transflective display mode, this module ensures crisp visibility and long-term reliability in both bright and dim environments.
Designed for flexible integration, the Arduino LCD 2004 I2C version allows simplified wiring with fewer pins, making it an ideal solution for compact projects. Developers can also connect it directly via the 6800 4/8-bit parallel interface with a standard 16-pin connection. Its outline dimension (98.0 × 60.0 × 14.0 mm) and viewing area (76.0 × 25.2 mm) provide a balanced design for industrial control panels, consumer devices, and educational projects.
Widely used in embedded systems, this Arduino LCD display 20×4 (also known as Arduino LCD2004) delivers stable performance powered by reliable controller ICs (AIP31066, HD44780, KS0066, SPLC780, ST7066). Whether for prototyping, teaching, or product development, the 20×4 LCD with Arduino offers an efficient and durable text display solution.
