Show the supply voltage of the RPi card

Greetings to the Pi-star team,
Is it possible to show the power supply voltage of the Raspberry card on the user dashboard, as well as the operating temperature of the card?
I think it can be useful to immediately highlight any voltage problems.
Thanks for your attention

With "card" I was referring to the Raspberry Pi board, consequently to the possibility of displaying the supply voltage of the Raspberry Pi
Thanks for the immediate feedback

No. Raspberry Pi's do not have any built in voltage sensors that you could query for power supply input voltage.
Well, to be factual -- there appears to be a sensor in the video core -- but it isn't power supply voltage
Code: Select all
pi-star@pi-star-3b(ro):~$ vcgencmd measure_volts core
volt=1.2000V
pi-star@pi-star-3b(ro):~$ vcgencmd measure_volts sdram_c
volt=1.2000V
pi-star@pi-star-3b(ro):~$ vcgencmd measure_volts sdram_i
volt=1.2000V
pi-star@pi-star-3b(ro):~$ vcgencmd measure_volts sdram_p
volt=1.2250V
