I thought of using an off the shelf board for datalogging my race car.

My issue. While I know the board is 12v tolerant and the xl1509 should handle the voltages seen in car (12-15v) I don't know if the remainder of the components will do so. Anyone with more firing neurons than me able to look at the diagram/pic below and tell me how quickly I'm going to release the smoke?<br></blockquote><div><br></div><div>I think the power supply is only part of the question.
