Raspberry Pi 4 Pinout
- The Raspberry Pi 4 has forty GPIO pinouts which can be used to read inputs connected and write the output according to input. Here all pins are explained in detail
Raspberry Pi 4 GPIO Pinout
- There are a total of forty pins existing on this Raspberry PI 4 model out of them twenty-six are GPIO pinouts
- This Raspberry model comes with two 5V pinouts, two 3.3 volts pinouts eight ground pins, and two reserved pinouts
- 5V pinouts are for the output of five volts power supply given through a Type C port. These pins 2 and 4 are on board.
- 3.3 volts pins are pins 1 and 17 on the board are used to power the outer components with 3.3 volts.
- Pins 6,9,14,20,25,30,34 and 39 are ground pins on the board that are used for circuit closing
- 27 and 28 number pins are reserved inputs used to make communication between I2C protocol and EEPROM
GPIO Pins Details
- These pins are used to perform numerous operations and each has its own function. Some pins work as input and some as output. The input voltage must be about 1.8 volts considered as low voltage and the voltage value fo these pins from 1.8 to 3 volts is high. Must provide a voltage of less than three volts for the safe operation of the board
Pulse Width Modulation Pins
- pins number 12, 13, 18, and 19 are pulse width modulation pins that perform the conversion of a digital signal to an analog signal. All pins can be used as software but some work as hardware PWM
Raspberry Pi 4 Serial Peripheral Interface Pins
- SPIO pins of Raspberry pi 4 are GPIO9 as MISO, GPIO10 as MOSI, GPIO11 as SCLK, GPIO8 as CE0 and GPIO7 as CE1.
- These SPI pins are used to make connections between devices like sensors or actuators with the board. Data is sent through Raspberry pin to devices through the use of MOSI and MISO used to receive data. SP communication is performed through the use of 5 GPIO pins ground, SCLK, MOSI, MISO, and CE.
- CE pins are used to enable or disable the circuit and SCLK pins operate as clocks for SPI communication
Raspberry Pi 4 Inter-Integrated Circuit Pins
- Through the use of I2C pinout, this board regulates the peripheral devices connected. Communication is performed through SDA and SCL pins. The data is sent through SDA pins and the processing speed of data is regulated through the SCL pin.
- EEPROM is small quantity data. In the case of this board GPIO2 pins is transmitting data through the use of SDA and GPIO2 regulates speed through SCl. While of EEPROM pin GPIO0 transmits data and the GPIO1 pin is used as a clock to regulate the speed of the data
Raspberry Pi 4 UART Pins
- The UART is a communication type where data is transferred in sequence bit by bit. There is a need for a transmitter and receiver for UART communication. In this communication, Raspberry Pi 4 comes with two default pinouts. The Pin GPIO14(TX) is transmitter for data sending and GPIO15(RX) is receiver pin
- Four extra pins are configured on board for UART.
