Hi guys, here is the next challenge.
I have a really power-sensitive system, which only needs to be active a few times a day, (to call the server and report some stuff), and else only wake up on a specific set of timers.
The rest of the time, it should be using as close to 0 amps as possible.
I have seen some timer gymnastics, but none to wake up the system from off.
And I have seen some interrupt pins used, but none to wake it up from off.
Should I have a microduiono or some other small board with limited capabilites to control the relay to the mother-board and just turn it on, or do you have more elegant solutions?
