If you get a Drone that does not have the receiver you want,how to process it ?
Here let me show you how to add an external receiver for a Mobula7 or Mobula7 HD
As we know,Mobula7 FC Built-in receiver,if the receiver builit-in is not the version you want,you can add an external receiver directly
Take Frsky receiver as an example
how to connect it?
first,you need not remove the exist receiver,because it will broke your FC,
then,weld the frsky receiver to your board directly,like this ,just weld the IR1 ,5V and GND
