Does any one know if Mission planner will be able to measure voltage on the Navio 2 servo rail?
Hi @Barry_Bolton,
It should be possible to configure it as a battery2 voltage value in MP.
You should:
- set up
BATT2_MONITORto3:Analog Voltage Only - change
BATT2_VOLT_PINto1:A1 - configure
BATT2_VOLT_MULTparameter to get the correct value of voltage in MP
Thank you Tatiana.
This does not work
Hi Barry,
It’d be great if your post here screenshots explaining where did you face difficulties.
I am facing difficulties in the fact that the settings that you recommended does not work. I will post a sreen shot alter
Hi!
To help you, I configured mine:
Do not forget to reboot the Navio after entering now settings.
BATT2_VOLT_MULT is from try and set: with coefficient = 1, value was 18.8, 0.266 give me around 5v
If Raspberry is only powered by USB, no power to the servo rail from Bec, battery 2 indicated voltage is around 0.5v.

BATT2_VOLT_PIN parameter is 1 (not A1)
You will have to compute VOLT multiplier (I use 0.266).

2 is for Pixhawk, Navio2,… power module.
If I enter 0.266 MP gives me “bad number”
If you set BATT2_VOLT_MULT it with mission planner, separator is , like 0,266
If you use GCS, separator is . so 0.266

OK entered like that and rebooting …
After reboot it always reverts back to 11.3
Still nothing
