A credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse.
The Raspberry Pi 4, The most powerful and feature-rich Raspberry Pi, an incredible improvement on previous boards. But:
What really is Raspberry pi 4 model B?
Raspberry Pi is the name of a series of single-board computers made by the Raspberry Pi Foundation, a UK charity that aims to educate people in computing and create easier access to computing education.
Raspberry Pi 4 Model B was released in June 2019 with:
- 1.5 GHz 64-bit quad-core ARM Cortex-A72 processor
- 802.11ac Wi-Fi
- Bluetooth 5
- Full gigabit Ethernet (throughput not limited), two USB 2.0 ports, two USB 3.0 ports
- Dual-monitor support via a pair of micro HDMI (HDMI Type D) ports for up to 4K
The Raspberry Pi operates in the open-source ecosystem: it runs Linux (a variety of distributions), and its main supported operating system, Raspbian, is open source and runs a suite of open-source software.
The Raspberry Pi Foundation contributes to the Linux kernel and various other open-source projects as well as releasing much of its own software as open source.
The Pi’s schematics are released, but the board itself is not open hardware. The Raspberry Pi Foundation relies on income from the sale of Raspberry Pi’s to do its charitable work.
What can you do with it?
It is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python.
It’s capable of doing everything you’d expect a desktop computer to do from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.
It is a little packed computer that is capable of building tablets, laptops, phones, robots, smart mirrors, to take pictures on the edge of space, to run experiments on the International Space Station — and that’s without mentioning the more wacky creations.
Unlike any typical device; in its cheapest form, it doesn’t have a case, and is simply a credit-card sized electronic board — much smaller from the parts you may find inside a computer/PC or Laptops.
It also provides a set of GPIO (general purpose input/output) pins that allow you to control electronic components for physical computing and explore the Internet of Things (IOT).
What are its specifications?
Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless networking and Bluetooth.
The Raspberry Pi 4 has upgraded USB capacity. Along with two USB 2 ports, you’ll find two USB 3 ports, which can transfer data up to ten times faster.
With variants of the Raspberry Pi 4 available, depending on how much RAM you need: 2GB, 4GB, or 8GB.
The fanless, energy-efficient Raspberry Pi runs silently and uses far less power than other computers.
It can decode 4K video, benefiting from faster storage via USB 3.0 (Type – C), and faster network connections via true Gigabit Ethernet. It’s also the first Pi that supports two screens at one — up to dual 4K@30 displays
