Hi,
I am using a cc3d board and I already connected my 4 ESCs to it. In the radio (receiver) port I am using arduino to receive data. If you dont know what it is, it does not matter, but I need to know what is the voltage that the VCC pin in the CC3D board receives from the receiver?
Do I really need to connect GND and VCC to the receiver pins, or I can ony connect the channels?
