Raspberry Pi is a low-cost, credit card-sized single board computer that has become wildly popular among hobbyists and enthusiasts for electronics projects. But is the Raspberry Pi actually running Linux? Given that it can function as a small computer, what operating system does it use?
Raspberry Pi Runs Raspbian, a Linux-Based OS
The standard operating system that comes pre-installed on Raspberry Pi boards is called Raspbian. Raspbian is a Debian-derived Linux distribution optimized specifically for the Raspberry Pi‘s hardware…
Other Linux Distributions Supported
While Raspbian is the officially recommended OS, Raspberry Pi systems can actually run many other Linux distributions. For example…
How Does Raspberry Pi Compare to Other Single Board Computers?
The Raspberry Pi is often compared to other single board computers (SBCs) used by developers and hobbyists. Here is how some key specs compare across different SBC options:
| Raspberry Pi 4 | Asus Tinker Board | ODROID-N2 | |
| CPU | 1.5GHz Quad-Core ARM | 1.8GHz Quad-Core ARM | 1.8Ghz Quad-Core ARM |
| RAM | 2GB – 8GB | 2GB | 2GB |
| GPU | Broadcom VideoCore | Mali-T764 | Mali-G52 |
| USB Ports | 2 x USB 3.0, 2 x USB 2.0 | 4 x USB 3.0 | 1 x USB 3.0, 1 x USB 2.0 |
| Ethernet | Gigabit | Gigabit | Gigabit |
| Wireless | 802.11ac WiFi | 802.11n WiFi | None |
| OS Support | Linux, Win 10 IoT | Linux, Win 10 IoT | Linux |
As we can see, the Raspberry Pi 4 model offers a very competitive feature set…
Real-World Electronics Projects Using Raspberry Pi
Here are some examples of practical electronics applications that can be built leveraging Raspberry Pi running Linux:
Home Automation
- Connect sensors, cameras, triggers to GPIO pins
- Control connected devices like lights, locks, thermostats
- Runs rules engine and web server to enable access
Kubernetes Cluster
- Leverage 5+ networked Pis to model a Kubernetes setup
- Provides hands-on experience managing containers at scale
- Useful for learning DevOps, container orchestration skills
Cryptocurrency Mining
- Install mining software like cpuminer or bfgminer
- Connect to mining pool account using Linux networking
- Mines crypto coins by pooling computer resources
Self-driving RC Car
- Attach sensors to detect obstacles
- Train machine learning module for visual recognition
- Program motors via GPIO to steer car safely avoiding objects
In all these projects, having an embedded Linux OS provides the hooks needed to…
The Rising Popularity of Raspberry Pi
Since launching in 2012, over 30 million Raspberry Pi units have sold globally making it one of most popular computing platforms.
A 2020 Statista survey found that 44% of Raspberry Pi users leverage it for programming education, while 31% use it for home automation projects, as shown in the chart below:
[Insert chart]According to a 2022 ResearchAndMarkets report, Western Europe and North America account for almost 60% of global shipments:

As Raspberry Pi finds new applications…
Linux Networking Capabilities on Pi
Connecting multiple Pis on a local network is straightforward thanks to the broad capabilities provided by Linux networking tools.
For example, IPs can be assigned manually or dynamically using dhcpcd or dhcp server like dnsmasq. Unique hostnames can be set in /etc/hostname and /etc/hosts files to identify Pis.
Shared folders across devices can be exposed using Samba:
[shared]
path = /home/pi/shared
guest ok = yes
browseable = yes
read only = noSecure remote shell connectivity can be enabled quickly thanks to inbuilt SSH server:
$ ssh pi@raspberrypi.local
pi@raspberrypi.local‘s password:
Linux raspberrypi 5.10.17-v7l+ #1459 SMP Tue Mar 29 16:55:27 BST 2022 armv7lPort forwarding, firewall policies, VPN tunnels can configured using iptables rules:
$ iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
$ iptables -A INPUT -i eth0 -p tcp --dport 443 -j ACCEPT
$ service iptables saveThis makes it very convenient to connect Raspberry Pis on a network to coordinate tasks, distribute workloads, backup data, and build responsive systems.
Programming Languages for Raspberry Pi Linux
As Linux offers cross-platform compatibility, Raspberry Pi supports a wide range of programming languages beyond just Python and Shell…
Tuning Raspberry Pi Performance via Linux
An advantage of having access to Linux OS configuration settings is being able tune Raspberry Pi capabilities for optimal performance in different scenarios…
Common Questions
Can you install Windows on Raspberry Pi?
Microsoft does provide a Windows 10 IoT Core OS that is optimized for Raspberry Pi, so yes it is technically possible to run Windows. However for the vast majority of electronics projects, Raspbian Linux provides much more robust functionality. Windows works better in limited cascade type applications…
Conclusion
In summary, given the Debian derived Raspbian OS that comes standard and ability to run other Linux distributions, Raspberry Pi firmly falls into the Linux system category…
