@Richarddbeck83 i know this is an old post…but i was just discussing this topic on another forum…i agree those tiny pins are a nightmare to solder…and to top it off i had the exact same experience with the polarity being wrong…i followed the pin out instructions from here on the forum i believe.i thought i misinterpreted them however after reading your experience just now i wonder if the schematic might be misleading also wonder how many people stopped and just went to raw voltage after either screwing up the pins or failing to realize the polarity was preventing things from working?
