I checked the connections and kabels, but i cant find a real problem. The Input voltage couldnt be to high for the converter, it came directly from the 4S LiPo Battery. The damaged/overheated pin is Pin 5, Vin, it is not shorted to ground (changing Ohms from 180 to 30, maybe because of the caps).
Was it maybe only bad luck? Is the convert not of good quality? Could be more damaged then only the converter
It could also be that i forget to cenect the antenna... i dont know it anymore i was to much in panic
. Could this have also that result?
Oh and can somebody help me to find a replacement, i looked at two local Online Shops, conrad.de and rs-online.com, also i looked at mouser.de (pretty expensive when it comes to shipping).
I maybe could also use a SOT23-5 cause on the board they dont use pin 4 (EN) it is bridged to pin 5 (VIN) via a 100kOhm resistor and i read on similar datasheets that this means allways on.
