I
A more advanced connection to the LVK204-25 is provided by the I
accomplished using a breadboard and the Breadboard Cable. Power must be supplied from your
breadboard or another external source. To dive right into your application and use the LVK204-25 in I
mode, get started with the guidelines below.
1. Set the Protocol Select switches.
2. Make the connections.

others are open.
Connect the Breadboard Cable to the Communication/Power Header on your LVK204-25 and
plug the four leads into your breadboard. The red lead will require power, while the black
should be connected to ground, and the green and yellow should be connected to your
controller clock and data lines respectively.
Pull up the clock and data lines to five volts using a resistance between one and ten kilohms on
your breadboard.
This time you're on your own. While there are many examples within the Matrix Orbital
AppNote section, www.matrixorbital.ca/appnotes, too many controllers and languages exist to
cover them all. If you get stuck in development, it is possible to switch over to another protocol
on the standard board, and fellow developers are always on our forums for additional support.
