HUD battery voltage

The display of the HUD battery voltage is as shown in the figure.
※ Firmware 4.0.3
How do I display voltage and current?

Use and configure a Power Module if your Flight Controller doesn’t have it built in.

The power module is connected as shown in the figure.

Well, what about “Configure”?

It is divided into the wiring from the battery to the FC (5V) and the wiring to the switchboard.

I will send you a simple wiring diagram.

That doesn’t make any sense to me. I meant configuration of the power module in Mission Planner. What Flight Controller is it?

I use PIXHARK’s Flight Controlle.

This page explains the steps required to use a power module.

Thank you very much. I would like to review the settings again.

It is solved. Thank you very much.
