FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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. Then there are the ground pins. There are eight ground pins and all of these are connected to each other; you can use any of these ground pins for your projects.

Detailed explanation-2: -All Raspberry Pi models have a number pins which can be used as I/O pins. Not all pins are I/O pins, some of them have a supply voltage (3V3 and 5V0), some of them are ground (GND). The pin header comes in two versions: B version: The old Raspberry Pi 1 B, isn’t sold anymore, had a total of 26 pins.

Detailed explanation-3: -8 out of the 40 GPIOs are connected to the ground. You can find them with the 3 letters GND. One additional warning: don’t ever connect the ground directly to a power supply pin (3.3V or 5V)! This creates a short circuit and can definitively burn your Raspberry Pi 4 board.

Detailed explanation-4: -There are 40 pins on the Raspberry Pi (26 pins on early models), and they provide various different functions. If you have a RasPiO pin label, it can help to identify what each pin is used for.

Detailed explanation-5: -There are 40 pins in this model and among them, 26 are GPIO pins. 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. The pins are numbered 2 and 4 on the Raspberry Pi 4 device.
