Fried (?) Stock turnigy 9X module (Vbat pin reversal)
Posted: Fri Jun 21, 2019 8:25 am
The other day i was doing the regular hack of replacing the stock antenna and moving it down ontop of the module. I used an sma pigtail for the job and soldered it on without much fuss. But when i placed it into the reciever to test it i accidentally got the pins in the wrong place and the voltage regulator on the module popped with a loud bang. I happened to have a spare 5v regulator laying around with matching pins so i replaced it. But after that no matter what i did (tried the module with 2 different 2.4ghz antennas on the sma connector - didnt work. I also put the old antenna on (without desoldering the sma) and that didnt work also) i couldnt get the reciever to bind/get signal. I checked to see if the module draws any current and at "normal" operation it draws around 33 mA and when the bind button is pressed it jumps to 34 mA so it seemed like it was fine. Can anyone tell me some other way to confirm it the module works or any advice in general really?
