This might be strange, but i guess you guys electrical engineers are the only one that knows that .
Our MCU is turned on by a push button . That means he sleeps most of the time, and when pushing the button he awakes up with interrupt .
The only concerns are :
- sending products that are in sleep mode, means- a little current is flow, is it safe in an airplane ? is it "professional" ? will it makes troubles in shipping? can a battery be connected to a product at all ?
2.If your products (pcb's) are sitting on the shelf for a while, that means your battery is going down, not too much , but it take some current . Is this, again "professional" to do? are you as hardware engineers design a circuit like this to be sent do another country ?
The mcu on sleep will take about 100uA , and the battery is 500mAH .
