Hello, I would like to leave the UDOO Quad (udoobuntu) constantly open to perform a simple task with a connected relay. Using the Quad for this simple task instead of a smaller, simpler board, might consume more power and keep idle a full blown computer but might have advantages in term of things that can be done, if I can maximize the usage and minimize power consumption. EDIT 1) Question 1 on installing a remote access software on the Quad to give me free access to my network from any place in the world was resolved in this thread: https://www.udoo.org/forum/threads/teamviewer-4-udoo.809/ 2) How do I save energy, minimize power consumption? The Due part for instance is used only to switch on/off the relay. It could be totally shut off until operation is requested. The Ubuntu part could sleep most of the time and wake up every few seconds to connect to a website to see if the relay must be activated and then go back to sleep. All sort of stuff that is not used could be deactivated (DAC, PWM?). What is the best way to save power in this scenario? (Of course I will have to wake up the board via web before remote access, that's ok). Any help/advice is appreciated, sorry for the long post. Thanks.
