Using Phantom 2 Vision ESC with Pixhawk

[Ender1618]

I have 4 Phantom 2 Vision ESCs (along with 4 Phantom 2 Vision motors [2 CW, 2 CCW]


And I would like to wire them to my Pixhawk Flight controller.

What would be the wiring set up? Any other components needed?

Essentially I am trying to merge components from these 2 kits into a Quadcopter:

Thanks for any help.

Why?

Because I am trying to utilize the components of those two bundles to build my quad.

Rather not have to buy a whole new set of motors and ESCs.

But i cant find much info on the ESCs, and how to make them work with the Pixhawk. The ESCs have more than the 3 pins, they have 4.

cant make out the connections on the picture, but it looks like it has solder pads for output to the motor.
the connect would need an input for the signal cable and the two power leads from the rail.
Or just take signal off the rail, and use a power module for power to the esc

Hi

the mcu looks like silabs, so those 4 pads are probably C2 protocol (or whatever it's called)
That 4-pin "signal" connector bothers me tho. The old ESCs used only two wires, which were soldered directly, so one SIG, other one GND. Maybe the other two, in this esc, are for the LEDs under the arm. It should be easy to figure that out with a multimeter.
It looks like a normal blheli (?) ESC, and should work, I dont think DJI were reinventing the wheel here.

so, basically, looking from the edge of the board towards the middle, the pinout on that conenctor SHOULD be:
1 - Orange = 1kHz
2 - Brown = Ground
3 - Orange = Motor control from Flight Controller, 400Hz
4 - Orange = Motor control from Flight Controller, 400Hz

so, pins 3 and 4 are signal wire, are already bridged together.
Pin 1, 1khz wire is for the LED control, doubt that pixhawk can do that on it's own

If you want, you can probably whip up an arduino controller for the LEDs, acconrding to the telemetry or something

10% = Off
20% = Red
30% = Green
40% = Yellow/Orange (Red + Green)
50% = Off
60% = LEDs go along with motor signal, i.e. the front LEDs flashing with start up sound (Motor on = LED on, Motor off = LED off)
70% = Off
80% = Off
90% = Off
100% = Off

oh, yes.. give credit, where credit is due. I found this information here:
