Booj asked:


I can use the car battery ( 12 V ) to supply the power but how would I go about to getting that power to the 3 portable devices that’ll be installed in the car ? GPS module takes 12v, microcontroller takes 5V and modem takes 3V.
Need a voltage regulator of some sort but not sure how to go about it.. ANY suggestions would be of great help.

   Park the car and use the power outlet in the Garage. Just kidding.

   Why would you need 3 devices.
