- How to choose the best single board computer for your project
- What are the best single board computers in 2023
Let’s get started!
What is a Single Board Computer?
A single board computer is a complete computer system built on a single circuit board. It has everything you need for a functional computer, such as:
- A microprocessor that acts as the brain of the computer
- Memory that stores data and instructions
- Input/output ports that connect to other devices
- And other features that vary depending on the model
Unlike a desktop or laptop computer, SBCs do not rely on expansion slots or external peripherals for additional functions. They are usually small, about the size of a credit card, or a bit larger, but still smaller than the average desktop PC.
SBCs are used for a variety of purposes, such as:
- Demonstration or development systems for testing new software or hardware
- Educational systems for learning programming, electronics, robotics, or artificial intelligence
- Embedded computer controllers for industrial, automotive, medical, or home automation applications
- Media streaming devices for playing music, videos, or games on a TV or monitor
- Retro gaming consoles for emulating classic games from various platforms
- Smart home devices for controlling lights, temperature, security, or voice assistants
- And many more!
Why Choose a Single Board Computer?
There are many benefits of using a single board computer over a traditional computer. Here are some of them:
- Cost: SBCs are generally cheaper than desktop or laptop computers. They range from $10 to $200 depending on the model and specifications. They also consume less power and generate less heat, which can save you money on electricity bills.
- Portability: SBCs are easy to carry around and can be powered by batteries, USB cables, or wall adapters. You can use them anywhere you have access to a monitor, keyboard, mouse, and internet connection.
- Customizability: SBCs offer a high degree of flexibility and creativity. You can choose from a wide range of operating systems and software that suit your needs and preferences. You can also connect various sensors, actuators, cameras, displays, or other devices to enhance the functionality of your SBC.
- Community: SBCs have a large and active community of users and developers who share their projects, tutorials, guides, and tips online. You can find answers to your questions, get feedback on your ideas, or join collaborative efforts with other enthusiasts.
How to Choose a Single Board Computer?
There are many factors to consider when choosing a single board computer for your project. Some of the most important ones are:
- Performance: The performance of an SBC depends on the processor, memory, storage, and graphics capabilities. You should choose an SBC that can handle the tasks you want to perform without lagging or crashing. For example, if you want to run complex applications or high-resolution videos, you might need an SBC with a powerful processor and ample RAM.
- Compatibility: The compatibility of an SBC refers to the operating systems and software that it can run. You should choose an SBC that supports the OS and programs you want to use. For example, if you want to use Linux-based OSes like Ubuntu or Debian, you might need an SBC with an ARM-based processor.
- Connectivity: The connectivity of an SBC refers to the input/output ports and wireless features that it has. You should choose an SBC that has enough ports and options to connect the devices you need. For example, if you want to use HDMI displays or Ethernet cables, you might need an SBC with HDMI and Ethernet ports.
- Expandability: The expandability of an SBC refers to the ability to add more functions or features to it. You should choose an SBC that has expansion slots or headers that allow you to attach additional boards or modules. For example, if you want to add more sensors or actuators to your SBC, you might need an SBC with GPIO pins.
