The standard version of the LVK204-25 allows for user configuration of three common communication

protocols. First, the unit can communicate using serial protocol at either RS323 or TTL voltage levels.

Second, it can communicate using the Inter-Integrated Circuit, or I

C protocol. Connections for each

protocol can be accessed through the four pin Communication/Power Header as outlined in the Serial

Connections and I

C Connections sections below.

Recommended Parts

The most common cable choice for any standard Matrix Orbital

display, the Communication/Power Cable offers a simple connection

to the unit with familiar interfaces. DB9 and floppy power headers

provide all necessary input to drive your display.

For a more flexible interface to the LVK204-25, a Breadboard Cable

may be used. This provides a simple four wire connection that is

popular among developers for its ease of use in a breadboard

environment.
