What is Raspberry Pi pin diagram?
There are 40 pins on the Raspberry Pi (26 pins on early models), and they provide various different functions….GPIO pins.
| GND | ground | Zero volts, used to complete a circuit |
| GP2 | GPIO pin 2 | These pins are for general-purpose use and can be configured as input or output pins |
Which pin is a serial interface pin Raspberry Pi 3 model B board?
Serial communication or the UART (Universal Asynchronous Receiver / Transmitter) pins provide a way to communicate between two microcontrollers or the computers. TX pin is used to transmit the serial data and RX pin is used to receive serial data coming from a different serial device.
What are GPIO pins in Raspberry Pi and explain types of pins?
GPIO pins are standard general-purpose pins that can be used for turning external devices, such as an LED, on or off. 5V and 3V3 pins are used to supply 5V and 3.3V power to external components. I2C pins are used for connecting and hardware communication purposes with I2C compatible external modules.
How many ground pins are in RPI model 3b+?
The Raspberry Pi 4 board has a GPIO header with 40 pins. This GPIO header is also the same for Raspberry Pi 3 boards, so this guide applies to both versions.
What are the parts of Raspberry Pi?

What is full form of GPIO?
General Purpose Input/Output (GPIO)
How many pins raspberry pi3?
40 pins
A Raspberry Pi 3 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.
How many pins are there on Raspberry Pi board?
Raspberry Pi models Of the 40 pins, 26 are GPIO pins and the others are power or ground pins (plus two ID EEPROM pins, which you should not play with unless you know your stuff!).
What is GPIO SDA?
SDA (I2C1 Data) is one of the i2c pins on the Pi, learn more about i2c. SDA includes a fixed, 1.8 kΩ pull-up to 3.3v, which means this pin is not suitable for use as a general purpose IO where no pull-up resistor is desired.
How many analog pins are available in RPi?
It has 8 analog inputs and the Pi can query it using 4 digital pins.
How many GPIO pins RPi 1?
Raspberry Pi models Of the 40 pins, 26 are GPIO pins and the others are power or ground pins (plus two ID EEPROM pins, which you should not play with unless you know your stuff!).
How many GPIO pins does the Raspberry Pi 2 Model B have?
The Raspberry Pi 2 Model B board contains a single 40-pin expansion header labeled as ‘J8’ providing access to 28 GPIO pins. (Pins 1, 2, 39 & 40 are also labeled below.) J8 Pinout (40-pin Header)
What do the pins on a Raspberry Pi mean?
5V: The 5v pins directly deliver the 5v supply coming from the mains adaptor. This pin can use to power up the Raspberry Pi, and it can also use to power up other 5v devices. 3.3V: The 3v pin is there to offer a stable 3.3v supply to power components and to test LEDs. GND: Ground is commonly referred to as GND.
What is a GPIO pin?
A standard interface for connecting a single-board computer or microprocessor to other devices is through General-Purpose Input/Output (GPIO) pins. GPIO pins do not have a specific function and can be customized using the software. Looking for R-Pi 3 Model B GPIO Pinout?
What is the difference between the Raspberry Pi Model B and Model B?
This higher-spec variant increases the Raspberry pi GPIO pin count from 26 to 40 pins. There are now four USB 2.0 ports compared to two on the Model B. The SD card slot has been replaced with a more modern push-push type micro SD slot. It consumes slightly less power, provides better audio quality and has a cleaner form factor.
