Find out how to check your Raspberry Pi’s specifications, including CPU, memory, and operating system details. Learn the commands to get this information from the command line interface.

Raspberry Pi is a popular single-board computer that runs on Linux-based operating systems. It has become a favorite for many makers, hobbyists, and developers due to its affordability, versatility, and expandability. One of the first steps when setting up or troubleshooting your Raspberry Pi is to know its specifications. This article will show you how to check the core specifications of your Raspberry Pi using a few simple commands in the command line interface (CLI).

CPU Information

The Raspberry Pi has different models with varying processing power capabilities. Here’s how to check which model you have and its CPU details:

  1. Open the terminal by clicking on the icon in the top left corner of your desktop or by pressing Ctrl + Alt + T.
  2. Type the following command and press enter:
cat /proc/cpuinfo

This will display detailed information about your Raspberry Pi’s CPU, including the model name, architecture, and revision number. The revision number corresponds to the specific model of your Raspberry Pi. For example, a “BCM2835” or “BCM2708” means you have a Model B or A, while “BCM2709” indicates a Model B+ or A+.

Memory Information

Knowing the amount of RAM your Raspberry Pi has is crucial for optimizing its performance and running resource-intensive applications. Here’s how to check it:

  1. Open the terminal.
  2. Type the following command and press enter:
free -h

This will display memory usage in human-readable format (e.g., MB or GB), including total RAM, used RAM, free RAM, shared memory, buffers, and cached memory. The “total” line shows the total amount of physical RAM available on your Raspberry Pi.

Operating System Information

To find out which operating system is running on your Raspberry Pi, type the following command in the terminal:

uname -a

This will display information about your kernel version, hardware platform, and operating system name. For example, it may show “Linux raspberrypi 4.19.75-v7l+ #1270 SMP Tue Sep 24 18:31:51 BST 2019 armv7l GNU/Linux” indicating that you are running Raspbian (a Debian-based OS) on a Raspberry Pi 4 with a 64-bit ARMv7 processor.

Conclusion

Knowing your Raspberry Pi’s core specifications is crucial for optimizing its performance and ensuring compatibility with the software you are running. By using these simple commands in the CLI, you can easily check your CPU, memory, and operating system information and make informed decisions about your Raspberry Pi setup.
