FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -This product should only be connected to an external power supply rated at 5V/2.5 A DC.

Detailed explanation-2: -The Raspberry Pi 3 Model B is the most power hungry platform released to-date and requires a 5.1V 2.5A power source.

Detailed explanation-3: -Sometimes, you’ll find sensors that are powered with 5V, but all the communication pins are running with 3.3V. In this case, no problem: you can use the 5V power pin from the Raspberry Pi to power the component, and then use any 3.3V GPIO for the communication.

Detailed explanation-4: -5V 2A USB power adapter is the perfect choice for powering single-board computers like Raspberry Pi, BeagleBone or anything else that’s power hungry!

Detailed explanation-5: -The Pi is powered from 3.3V and the ADC from 5V. The digital output voltage for the ADC is 4.1V, which exceeds the 3.3V supply voltage for the Pi.
