Hi! I think UDOO is the answer for what i need. Im building a smart car tracker, part of the solution is based in the arduino ( read the sensors and wake up the other board ) and the other part is the processor, where all the logic is. Can i make the I.MX6 sleep and the SAM3X8E stay active? When i get some kind of read from the sensors, like the engine turned on, can SAM3X8E wake up I.MX6? Have any power consumption measurement using oly the SAM3X8E? If this is possible, its the answers for all my problems. Thanks!!!
