The optative items in Brazilian vehicles are limited on basic versions; therefore, it is not all people that can access technologies present in newest cars. Once many vehicles does not come out from factory with an Onboard Computer, which is present in its expensive models, it has been proposed the construction of a dispositive that shows some information about the car, like engine coolant temperature, fuel tank level, vehicle instant speed, external temperature and some other important information. It were chosen rapid prototyping platforms for testing and for the development of the final equipment, as well as all-necessary modules for being possible the communication between the developed device and the car’s network. It was necessary to understand some communication protocols between microcontrollers, like SPI (Serial Peripheral Interface) and between the developed device and the test vehicle (CAN, or Controller Area Network). Finally, the device were conditioned in a wooden box and provisionally installed in the test vehicle, in order to evaluate and validate the developed equipment.
