The 27979 Parallax 4x20 Serial LCD (Backlit) provides a very functional, low-cost LCD that can be easily controlled by a BASIC Stamp.

 

The LCD display consists of four lines by 20 characters and provides basic text wrapping so that your text looks right on the display. In addition, the Serial LCD also provides you with full control over all of its advanced LCD features, allowing you to move the cursor anywhere on the display with a single instruction and turn the display on and off in any configuration. It supports the same visible characters as the BASIC Stamp Editor’s Debug Terminal (ASCII Dec 32-127). In addition, you may define up to eight of your own custom characters to display anywhere on the LCD.

• A professional-looking text user interface on any microcontroller application
• Easy-to-implement serial debugging without a PC
• Real-time sensor data output on autonomous robotics applications

This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn't supported by Parallax, but it's possible to make this connection with a few dollars of parts.
