Raspberry Pi 4 B GPIO Pinout:

The Raspberry Pi 4 Model B features a 40-pin GPIO (General Purpose Input/Output) header that allows users to interface with various hardware components and peripherals. Here's a brief overview of the GPIO pinout for the Raspberry Pi 4:

  • Pins labeled as GPIO refer to General Purpose Input/Output pins.
  • Pins labeled as +3V3 and +5V are power pins providing 3.3 volts and 5 volts, respectively.
  • GND refers to ground pins.
  • Other pins have specific functions, such as I2C (SDA1, SCL1), UART (TXD0, RXD0), SPI (MOSI, MISO, SCLK, CE0, CE1), and more.

To check the pinouts of Raspberry Pi 4 in Raspbian OS (now known as Raspberry Pi OS), you can use various command-line tools and utilities. Here are some methods:

GPIO Utility:

The GPIO utility provides a command-line interface to query and configure the GPIO pins. Open a terminal on your Raspberry Pi and run the following commands:

# Install the GPIO utility if not already installed
sudo apt-get update
sudo apt-get install wiringpi
# Run the gpio readall command to display the pinout
gpio readall

This will provide a table with the status and function of each GPIO pin.

Raspi-GPIO Utility:

The raspi-gpio utility is another tool for inspecting and manipulating GPIO pin status. Run the following commands:

# Install the raspi-gpio utility
sudo apt-get update
sudo apt-get install raspi-gpio

# Run the raspi-gpio readall command
raspi-gpio readall

This will display the GPIO pinout similar to the GPIO utility.

Pinout Command:

The pinout command provides a graphical representation of the GPIO pinout. If it's not installed, you can install it using the following:

# Install the pinout command
sudo apt-get update
sudo apt-get install python3-gpiozero
# Run the pinout command

This will show a visual representation of the GPIO pins and their functions.

What you need to get started with Raspberry Pi 4B 4GB:

To get started with the Raspberry Pi 4 Model B single-board computer (SBC), you'll need a few essential components. Here's a basic list to help you get started:

  • MicroSD Card: A microSD card is required for storing the operating system and your data. It's recommended to use a high-quality, high-capacity microSD card (at least 8GB) like this one for better performance.
  • Power Supply: The Raspberry Pi 4 uses a USB Type-C connector for power. Ensure you have a compatible power supply with a rating of 5V and at least 3A to provide sufficient power to the Pi. You can get the original Raspberry Pi 4 power adapter here.
  • Micro HDMI Cable: The Raspberry Pi 4 features dual micro HDMI ports for video output. Depending on your display, you may need a micro HDMI to HDMI cable. If you have a HDMI cable and want to use it, you can get this Micro HDMI to HDMI converter.
  • Display: A monitor or TV with an HDMI input for connecting to the Raspberry Pi. Ensure it supports the resolution you plan to use.
    • There are HDMI displays of different sizes on the site, from which you can choose the version you want. Some displays have a touch screen and some don't. Some of touch screen are resistive and some other are Capacitive. So, be careful in choosing between them.
  • Keyboard and Mouse: USB or wireless keyboard and mouse for interacting with the Raspberry Pi. There are official Raspberry Pi keyboard at store that you can get it.
  • Case (Optional): While not strictly necessary, a case can help protect your Raspberry Pi and keep it dust-free. There are various cases available, ranging from simple to more elaborate designs.
  • Cooling (Optional): Depending on your usage, you may consider adding a heatsink or fan for cooling. The Raspberry Pi 4 can generate more heat than previous models, especially under heavy loads. You can get a case with cooling function like this one to extend the life of your Raspberry Pi.
  • Operating System (OS): Download and install an operating system on your microSD card. The official Raspberry Pi OS (formerly Raspbian) is a popular choice and comes with many pre-installed applications.
  • Ethernet Cable (Optional): If you prefer a wired internet connection, you can use an Ethernet cable like this to connect your Raspberry Pi to your router or network switch.
  • Accessories (Optional): Depending on your projects, you may need additional accessories like sensors, LEDs, breadboards, and other components for experimentation and building projects. There are various shields you can get to test it with Raspberry Pi.

What you can do with 8GB version of Raspberry Pi and not with 4GB version

The primary difference between the 4GB and 8GB versions of the Raspberry Pi 4 lies in the amount of available RAM. The increased RAM in the 8GB version can be advantageous for certain applications and workloads, but for many general-purpose uses, the 4GB version may be sufficient. Here are some considerations:

Use Cases for 8GB Raspberry Pi 4

  • Memory-Intensive Applications: Running multiple memory-intensive applications simultaneously may benefit from the additional RAM. This includes tasks like large-scale data processing, virtualization, or using memory-hungry software.
  • Virtual Machines: If you plan to use your Raspberry Pi 4 as a host for virtual machines using hypervisors like QEMU or others, the 8GB version can provide more room for allocating memory to VMs.
  • Software Development: For complex software development projects or compiling large codebases, the extra RAM can be beneficial.
  • RAM Disks: Creating RAM disks for temporary storage or caching purposes can make use of the additional RAM, resulting in potentially faster access times.
  • Multitasking with Large Files: If you frequently work with large files, such as high-resolution images or video editing, the extra RAM can help in managing these files more efficiently.

Use Cases Common to Both Versions

  • Web Browsing: Casual web browsing and accessing standard websites are generally feasible on both the 4GB and 8GB versions.
  • Media Playback: Streaming video, audio playback, and other media-related tasks are well within the capabilities of the 4GB version.
  • Home Servers: Setting up home servers for file sharing, media streaming, or light-duty server tasks can be accomplished with the 4GB version.
  • Educational Projects: The 4GB version is suitable for various educational projects, learning programming, and experimenting with hardware.
  • IoT Projects: Internet of Things (IoT) projects, sensor monitoring, and simple automation tasks are well-supported by the 4GB version.
