Hello All,
Still the same problem: on connection to GCS it shown zero v. I try to flash by different firmware but same result. Any suggestion?
Thank you, Valentin.

Hi Joerg,
Thank you for quick answer. Yes, flashing was successful. I flashed it with 6.7 and with 7.1. All functions are working correctly. Only this problem with voltage. And off course I can not fly because motors are not working properly
I have not any ideas how to fix it for a long time.
Thank you, Valentin.

You need to connect the Vsens/GND between M4 and N4
Then select "external voltage sensor" in misc settings in QGC. Write to flash and restart.

Jussi, sorry.
But I have Autoquad 6. My mistake, did not write about it. Can I do something with this board?
Thank you,
Valentin.

AQ6 board has internal voltage sensor, it should work if the internal sensor is chosen under misc settings in QGC.
If not, it points to a problem with the board, most likely a connection problem on the voltage divider (R3 and R4) or connection problem to the ADC pin on the STM32 that reads the output of the voltage divider (Pin18).

Heh,
It's looks like I can not fix it by myself.
Very strange - all time it was powered from BEC by 15 v. No any visual defects. It was from the beginning. No one fly was made.

Where did you buy this board?
