Esplora 5v -> 3.3v

Using Arduino General Electronics

Hello.
How can I send a 3.3v signal from my arduino esplora?
I have this: Bi-Directional Logic Level Converter Hookup Guide - SparkFun Learn

Use a voltage divider sing a 510R series resistor and a 1K to ground.

Sorry I didn't understand. Is the module that I linked useful?
