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.

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

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

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.

can we measure battery power % in raspberry pi if you use buck converter
@mathewlawrenceml 3 жыл бұрын
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

@@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

@@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.
