Raspberry Pi 4 Model B 4GB
What is the Raspberry Pi Single Board Computer?
The Raspberry Pi is a series of small single-board computers developed by the Raspberry Pi Foundation in the UK to promote the teaching of basic computer science in schools and in developing countries. The original model became far more popular than anticipated, getting outside its target market for uses such as automation, multimedia, robotics, IoT, and now even in IR4.0.
The board itself does not include peripherals (such as keyboards and mice) or cases. However, there are many accessories to have been included in several official and unofficial bundles, making it highly customizable. Generally, the Raspberry Pi board comes with CPU, GPU, RAM, HDMI multimedia port, USB ports, wireless or wired connectivity, Camera interface, microSD card slot, and General Purpose Input/Output Pins. There are millions of Raspberry Pi boards in universities, polytechnics, schools, factories, maker spaces, and even the space station.
4GB DDR4 RAM!
Yes, the Raspberry Pi 4 Model B with 1GB, 2GB, and 4GB RAM was launched in June 2019 and it is already at par with the entry-level x86 PC system and many had tried it to replace a desktop computer. And here is the comparison table between Raspberry Pi 4 Model B vs Raspberry Pi 3 Model B+:
The Highlights:
Raspberry Pi as Desktop Computer
The Raspberry Pi 4 Model B is being packed as a desktop computer kit and many have tried it, and are amazed by the performance of this small single-board computer, even with the 2GB RAM version. Imagine the performance that it can offer with a higher RAM size of 4GB or 8GB? Besides the significantly faster boot speeds and much better performance for CPU-heavy tasks like emulation and media center usage; it will be perfect for AI (Artificial Intelligence), maybe multimedia editing, Web server, or any application that requires huge memory! We have been using the Raspberry Pi 4 Model B with different RAM sizes as daily online web-based work including accessing emails, Google Drive, and playing YouTube videos via the Chromium browser. We are satisfied with it!
Faster USB and Ethernet
The Raspberry Pi 4 Model B has two USB 3.0 ports, for up to 10x faster transfer speeds than USB 2.0, perfect for connecting fast peripherals like SSDs and flash drives. There are also two USB 2.0 ports for connecting less speed-dependent peripherals like keyboards and mice. And the USB boot firmware has been released to a stable version and preloaded on the board since early 2021.
The true gigabit ethernet on the Raspberry Pi 4 Model B, is designed for super-speedy wired networking while retaining the Power-over-Ethernet capability (requires additional Raspberry Pi PoE HAT), making it perfect as a media server and network-related projects. We manage to get 940 Mbits/s through Iperf3 on Raspberry Pi 4 Model B’s Ethernet port.
4K Multimedia, Dual Display
With the Video VI GPU, Raspberry Pi 4 Model B is capable of supporting 4Kp60 multimedia. You can use much larger displays with crisp, sharp, high resolution. Use the H.265 4Kp60 hardware decoding to watch 4K movies in your favorite media center distro.
For the first time, you'll be able to use dual HDMI displays with the Raspberry Pi. This is great for working on a bunch of different tasks at the same time without having to work in a tiny window.
Of course, you will need the micro HDMI cable, we have you covered! Get the official micro HDMI cable here.
More Peripherals on GPIO
Alongside the major upgrades, Raspberry Pi 4 Model B still keeps backward compatibility on the 40-pin GPIO. So generally, all of the HATs (Hardware Attach on Top) are still compatible with this powerful board. However there are also some upgrades on the 40-pin header, the new Raspberry Pi has support for an additional 4× UART, 4× SPI, and 4× I2C connectors.
USB-C for Input Power
With the USB-C socket for Input power, Raspberry Pi 4 Model B is able to get more power (preferred 15W or higher) and deliver higher power for its peripherals such as USB 3.0, e.g.: HDD and SSD.
