I recently received one of these chips (micro USB variation) and hooked it up to a single 2000mah LiPo cell and two of the leads on the IC started to spark, sizzle, and a small flame occurred....
I mean this is pretty simple stuff and I'm sure I attached the battery leads to the correct terminals as seen in the picture. Could it be that the +/- as printed on the board is flipped?
(I made this picture for the china seller of the board so please don't be offended by my arrowing)
Any help is HUGELY appreciated.
Also, if you leave the battery connected to this circuit, does it draw any current? I assume it does given that it's a circuit...any idea how much? Will a 2000mah cell last for weeks, months if just left from a full charge?
Also, OP, thank you so much. This is exactly what I was looking for.
Edit: Upon inspection, I note that the "Batt +, Batt -" are printed on the same sides as the OP pictures, although reversed running towards the USB connector instead of away. Dunno if that means anything.
Update: I just reversed the batt polarity (just tapped the leads) and the same two leads on the IC started sizzling/sparking. :shrug:
