Arduino Uno, ESCs without BEC quadcopter

[Nazty]

I posted a thread earlier that has since been resolved. The current issue was resolved, but the main project still has not been completed. I almost had my Quadcopter fully completed until I short circuited my Naze32 board. So I bought 3 more boards off amazon for $30. Hopefully I didn't get ripped off.


While I wait, I figured I try and connect the quadcopter to an Arduino Uno Board. The problem is I'm following The Schematic posted below. My motors are connected to ESCs without BEC. From my understanding that means it only has a ground wire and a signal wire. I do have a voltage converter that is connected to my PDB along with the motors and battery. How can I modify the schematic for my specific type of motors. I notice that all other google images only post pictures of Arduino Unos with BEC ESCs. Noob mistake I suppose :\. Also, is there a schematic for Raspberry Pis with the same scenario? Thank you again for any guidance or step toward the right direction!

You ripped yourself off. Naze32 were good back in the day. You could of had 2x F3 boards for that. I been through 7 naze32 boards, they just break on there own for no reason. I had 3 SPF3 boards now for about 5 months. No gripes still going. They have the blheli pass through as naze32 does not.

That's incorrect, all ESCs need and have BOTH +/-. Which are the thick BLK/RED wires in your diagram. An ESC with a BEC will have a thin 3 wire connector with a RED 5V wire, if there is no BEC there will only be 2 wires in the connector for the signal.

I see no direct connection of the LiPo NEG to the ESCs so the motors can get the full range of battery voltage when signaled. I'm just winging it but something like this makes more sense.
