Hardware isn't my strong side. Please excuse me if this is an ignorant question.
I would like to use the navspark as a logger. I soldered the connector wires to the adapter board, plugged in the 3.7V Lipo battery shown below and noticed that the adapter board got hot very fast. Light of the navspark board (not in the photo) did not switch on.
Did i solder the connector the wrong way round? It does seem to match the photos i found on this website.
