NDTC4002001 | 40x2 LCD Arduino i2C Character 4002 LCD Display STN LCD Blue White Backlight
The 40×2 LCD display is a high-capacity character module that shows 2 lines with 40 characters each, making it an excellent solution for applications that require large text output and detailed information display. Often referred to as a 2×40 LCD display, this module provides 80 character positions, ideal for industrial control panels, measurement equipment, and data monitoring systems.
Built with STN-LCD Blue technology and a transflective mode, the 40×2 module offers crisp readability under both strong light and dim environments. With a wide viewing area of 153.0 × 17.0 mm and a durable outline size of 182.0 × 33.5 × 13.6 mm, it balances large text display with a slim design.
Supporting both 3.3V and 5V operation, the 40x 2 display can be easily integrated into embedded systems using the standard 6800 4/8-bit parallel interface and 16-pin connection. Compatible with Arduino and similar development boards, it allows makers and engineers to build projects quickly and efficiently.
Whether for professional equipment or DIY electronics, this 40×2 LCD display delivers stable performance, long-term durability, and expanded text capacity for advanced applications.
