Pixhawk 4 ESC wiring setup

I think he mean to say it’s Good way if you connect the ESC to power management board because that’s why they are designed for. If the ESC need allot of power so better to leave it to distribution board.

On some Frame, the ESC could be connected directly and for Basic use. For example, the Tarot 650 Sport and DJI F450, the ESC (PWR ) could be solder on the main board . In this case is more simple and clean(my point of view). If your frame have not integrated the power distribution, the Power management seems me board is usefull.
I think remove this Power management Holybro (two electrical source) but only one battery on my Quadcopter by one more simple.

Did you connect it this way?
If so did you set any parameters or such?

I have connected it directly, as per my initial diagram. Connections are working well and everything is firing up.

What about your receiver, what make is it; and how did you connect it?

And did you use the PWM breakout board anywhere?

For the receiver I used the PPM RC input connector on the board and no, i have not used the PWM.

@lloydrayner Thanks for this thread!

I’m just about to do the initial setup for my Pixhawk 4 now that QGC will recognise it. :slight_smile:

Hello !
I am using DJI F450. I believe I can use the power distribution of the frame to power the ESCs (see image below). Will I be required to use the power distribution board of Pixhawk 4 ?

In this case, you can use the Pixhawk 4 Power Module (PM07)( http://www.holybro.com/product/pixhawk-4-power-module-pm07/ ) but it is not really useful.or PM02( http://www.holybro.com/product/pm02/) is more simple and more llight…

Hello @Serge !
Yes I agree. But then how will I connect the esc signal wires to Pixhawk 4? I need PM07 (will connect at M pads) for that purpose.

Hello

Sorry for the delay !!

For each ESC, the power (6S for Tarot 4114, for my drone) is connected directly on battery.
The PWM command ESC use by a cable connected individually on splitter with 8 channels (include in the Holybro package).

The splitter on my Drone is hidden under the Pixhawk close ESC cables.

(See photo with an another splitter for AUX channels)

Got it ! Thanks much @Serge : )

Hi,
I am wiring the same circuit on your picture.Does it work on your drone?

Hello

On the photography, the splitter was used for AUX port. But you can use the first Splitter for the ESC.
On The Pixhawk4 , two ports are aviable the first for connect the ESC and the second for AUX (default configuration).
