Title: Voltage of cc3d receiver VCC
Post by: batata003 on October 02, 2016, 06:38:19 pm

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?

If your arduino is already powered you only need GND and signal(s).

The voltage in receiver port is the same voltage provided by Esc/Bec.
You can check the schematic or simply measure with multimeter.

Yeap, arduino is already powered externally (24v) and it is already connect to the common GND and 24v. So can I only connect the channels? Do I really need to connect the GND pin of the receiver port of CC3D to the common GND of my circuit?

Why you need 24v to power a Arduino board ?

Can't be simply powered through +5v provided by Esc/Bec ?
