Serial Interface Alphanumeric Liquid Crystal Display Modules

Contact Matrix-Orbital for pricing and information on this product.

The Matrix Orbital LCD module line covers most of the popular LCD configurations. Control of the modules has been simplified to a set of commands delivered to the modules via RS-232 and I2C communications protocols.

Ease-of-use is the paradigm.  These modules are meant to save time and money.  Every effort has been made to ensure that tedious timing relationships and special conditions typical of display controllers are eliminated from the interface. For instance, the modules are fully buffered so that no delays in transmission are ever necessary.
