LCD2041
Intelligent 20x4 Serial Charcter LCD display engineered to quickly and easily add a powerful HMI to any application. Versatile LCD2041 can be used with virtually any controller, has outstanding speed and is capable of bar graphs or large digits
The LCD2041 is an intelligent Serial 20x4 LCD display designed to decrease development time by providing an instant solution to any project. With the ability to communicate via serial RS-232/TTL and I2C protocols, the versatile LCD2041 can be used with virtually any controller. The ease of use is further enhanced by an intuitive command structure to allow display settings such as backlight brightness, contrast and baud rate to be software controlled. Additionally, up to thirty-two custom characters such as character sets for bar graphs, medium and large numbers may be stored in the non-volitile memory to be easily recalled and displayed at any time.
The LCD2041 comes in a wide variety of colors including the standard yellow/green or inverse yellow, the popular blue/white and the crisp white/grey as well as inverse red which is excellent for viewing at night. Extended voltage, and temperature options are also available, to allow you to select the display which will best fit your project needs.
