So basically it is damaged, right? Considering that I am feeding from the 3.3 v from the arduino and I have fed the arduino with a battery for a while.
Here is my theory:
Considering that the amount of current drawn from the 3.3 v is multiplied by 2, I have been giving a excessive amount of current which after a while damaged the module and now it does not work.
Is it right?
PS. The battery is a 7.4 v 1300 mAh lipo
