Probe
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 I2C
protocol. Connections for each
protocol can be accessed through the four pin Communication/Power Header as outlined in the Serial
Connections
and I2C
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.
