FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -There are two 5V pins and two 3V3 pins, as well as a number of ground pins (0V), which are unconfigurable. The remaining pins are all general-purpose 3V3 pins, meaning that the outputs are set to 3.3 volts and the inputs are tolerant of 3.3 volts.

Detailed explanation-2: -A Raspberry Pi 4 board has 40 pins on it. Among these pins, we have four power pins on the Raspberry Pi, two of which are 5v pins and another two are 3.3v pins. The 5v power pins are connected directly to the Raspberry Pi’s power input and we can use these pins to run low power applications.

Detailed explanation-3: -Like every Raspberry Pi model ever made, the Raspberry Pi 4 has no power switch. The default way to turn on a Raspberry Pi is to just plug it in. When you’re ready to turn it off, you shut down the OS and then unplug the cable.

Detailed explanation-4: -The Raspberry Pi model includes two 5V pins, two 3.3V pins, eight ground pins and two reserved pins. 5V pins: The 5V pins are used to output the 5V power supply provided by the Type-C port.

Detailed explanation-5: -Raspberry Pi 4 Tech Specs 2 USB 3.0 ports; 2 USB 2.0 ports.
