Figure 3: Communication/Power Cable

(SCCPC5V)

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.

Figure 4: Breadboard Cable (BBC)

For a more flexible interface to the LK402-25, 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.
