NDTC2004001 | Arduino LCD2004 20x4 LCD Display Module with I2C Support FSTN LCD Grey
The display 20×4 LCD is a versatile character module that shows 4 lines of 20 characters each, making it perfect for text-rich applications such as control panels, instruments, and educational projects. Built with FSTN-LCD Grey technology and a transflective mode, it provides excellent contrast and readability under both indoor and outdoor lighting conditions.
Designed for flexibility, this Arduino LCD display 20×4 supports both 3.3V and 5V operation. Developers can connect it via the standard 6800 4/8-bit parallel interface or simplify wiring by pairing it with an Arduino LCD 2004 I2C adapter. The i2c 2004 LCD option reduces pin usage while maintaining stable communication, making it ideal for compact embedded systems.
With an outline size of 77.0 × 47.0 × 13.0 mm and a viewing area of 60.6 × 22.6 mm, this Arduino LCD2004 module balances compact design with clear display capacity. Supported by reliable controller ICs (HD44780, KS0066, SPLC780), it ensures consistent performance and long-term availability for both DIY and industrial applications.
