The title of my topic says it all.
I was desperately testing different codes for my mobile robot, all of a sudden I hooked up the wires from my 7.4V @ 1Ah LiPo battery in the Vin and GND pins backwards and then my board crashed
. I didn't look up at the wires polarity properly cause I had been doing that for days but s**** happens.
Fortunately I could use it again, powered it via USB cable, but given the circumstances I'll need an external power source. The thing is that I don't know what component has been damaged; thought it could be the voltage regulator, but if anyone could give me an advice on this, I'll truly appreciate it.
And even more if there is a way of fix it, even though it sounds pretty difficult.
Thanks in advance
