Guys need help in soldering for dys f4 pro
#1
I dont know how to make my battery voltage to be displayed.
I use dys f4 pro
when i connect to betaflight i couldnt able to get voltage of my battery status.So help me with where should i solder.
thanks

In BetaFlight, do you have "Onboard ADC" selected under "Power & Battery"?

If it is, try saving the settings again. Make sure the FC reboots after the save by checking the log at the top. (click "Show Log" - Top right)

Are you powering the board directly from the LiPo, or are you supplying power via a 4in1 ESC?

As far as I can establish you need a direct connection from the FC to the battery for it to read the battery voltage.

Can you post a photo of your setup?

Stupid question, but do you have the flight battery connected when you are looking at this in the configurator?

I had problems with DYS before and voltage. Read jflyer post. It worked for me.

Actually i used a pdb for powering esc and a connection from pdb to fc.

Also just check the picture even the battery is connected it shows not connected
and one more thing i didnt understood is what is bat+ in dys f4 diagram.

Photo of the PDB wiring to the FC, and please confirm that the battery IS connected when using the configurator?

Have you used a regulated 5v out from the PDB to the FC? If the FC is not receiving battery voltage it will not know what the battery voltage is, to display it.

I'm pretty sure that the Bat + (on the LED and FPV connection points) is to provide battery voltage to peripherals that require more than 5v, such as some VTX. However to output battery voltage will require that the FC is powered by direct LiPo voltage, rather than a regulated voltage from the PDB.

 If you can take a photo of the wiring it might help, also if you can provide a link to the FC you bought..?

+1. 

Having a photo of how you soldered the FC, PDB etc. will answer a lot of our questions.

I'm confused, why are you using a PDB? The FC is AIO PDB & BEC, adding another PDB seems like its just dead weight?
