WiPy 2.0 Board Heated while connecting Lipo
I am having WiPy 2.0 with Pysense. To test the device remotely, I tried connecting Li-Po 3.7V 500mAh battery in the li-po pin. At that time, the board Heated up and I removed them. I have checked proper li-po pin connection, its good. but why the board getting heated up.? Do I connect any other battery?
note: I haven't connected USB at this time. And also, No heat when connecting USB.
Changed the polarity and its working.
a) did the board work with the LiPo? If not, the polarity may be wrong.
b)Is the board now working with USB?
