Powering a pi

[@brentjohnson6654]

Good video. I think the volts for the pi a bit higher like 5.1-5.5? Do you get a low power warning on the pi desktop? Again, thanks for the video.

[@dalesmith8666]

what's the part number of the device? (on the chip)

[@mmdirtyworkz]

Why not use micro USB connection for power, leaving GPIO pins free for other stuff?

[@mathewlawrenceml]

You can do. I just did it this way because I had the parts to do it this way and for ease. As in this use case I have no need to use the GPIO.

[@mmdirtyworkz]

@@mathewlawrenceml Oh I see. Just starting with the Pi so I watch as much videos/guides as I can. Awesome setup you got there!

[@mathewlawrenceml]

@@mmdirtyworkz thank you. And good luck with your projects.

can we measure battery power % in raspberry pi if you use buck converter

[@mathewlawrenceml]

You would need a external ADC as the pi has no analog inputs. But it could be done.

@@mathewlawrenceml I have ads1115 but my battery is 12volt and I use buck converter to get 5volt ,will ads1115 give me reading from buck converter directly

[@mathewlawrenceml]

@@khushsharma no your need to use a resistor devider to bring the voltage down to a safe level. As feeding 12v into the ADC will damage it. Say for example you used a 24k resistor from the 12v to an input of the ADC and a 9.1k from the same input down to 0v that will give you a 3.3v I put for 12v battery level.

@@mathewlawrenceml no sir my question is ,I am getting 5v from buck converter which is connected to 12 volt battery. Can I measure battery level from that 5v( buck converter ) by ads

[@mathewlawrenceml]

@@khushsharma not after the buck no. You'll have to take a sample from the input of the buck. Unless there buck chip has any Comms on it. But that would require looking for that chips datasheet ect.
