Generally it is best to understand the [hardware requirments](/Hardware_requirements) first and ensure that your sensors are producing signals that speeduino can understand and control. Then decide the board version that works best with the target instalation [(v0.3)](/boards/V03) or [(v0.4)](/boards/V04) or a PNP variant.
The links below will help give an overview of each area, how it should be configured and how it relates to the overall setup.
