A single-board computer called the raspberry Pi 4 was created by the raspberry Pi Foundation. Released in June 2019, it is the fourth model in the Raspberry Pi line. A small-sized computer called a Raspberry Pi 4 runs the Linux operating system. It is a tiny computer that functions largely as a quick way to run sophisticated programs. The Raspberry Pi 4 has a number of improvements over the Raspberry Pi 3B+, which it replaces. The Raspberry Pi 4 contains all the necessary wired and wireless communication systems used in most of the smart applications. Raspberry Pi 4 is used in variety of projects, including home automation, media centers, retro gaming consoles, robotics and many more.
The enhanced processing capability, which comes from a quad-core, 64 bit ARM Cortex-A72 CPU operating at 1.5GHz, is the most obvious enhancement. Moreover there are now 1GB, 2GB, and 4GB variants of RAM available. Dual-band 802.11ac wireless networking, Bluetooth 5.0, Gigabit Ethernet, two USB 3.0 ports, and two 2.0 ports are all features of the Raspberry Pi 4. Furthermore, it includes two micro-HDMI connections that may enable a resolution of up to 4Kp60.
Because of versatility, and flexibility, the Raspberry Pi 4 has a number of benefits, including:
- High Performance : The Raspberry Pi 4 is significantly faster than its predecessors, with a quad-core Cortex-A72 (ARM v8) 64-bit SoC running at 1.5GHz. There is also up to 8GB of RAM included, which is more than enough for the majority tasks.
- Connectivity : The Raspberry Pi 4 has Gigabit Ethernet, Wi-F, and Bluetooth built in, making network communication simple. Moreover, it has 3.5mm audio jack, many USB ports, HDMI and Display port outputs.
- Compatibility : The Windows 10 IOT Core, Linux-based operating systems like Raspberry Pi OS, and other third-party apps are all compatible with the Raspberry Pi 4.
- Expandability : A 40-pin GPIO header that is built into the Raspberry Pi 4 makes it simple to connect to expansion boards and external devices. This makes it a well-liked option for DIY tasks and prototype.
- Energy Efficiency : Because of its energy-saving design, the Raspberry Pi 4 uses only a few watts of power. This makes it the perfect option for battery-powered crafts or tasks requiring little power.
- Low Cost : The Raspberry Pi 4 is reasonably priced when compared to other single-board devices or conventional desktop computers. For hobbyists, students, and organizations with tight budgets, this makes it a cheap choice.
Schematic Of Raspberry Pi 4
The raspberry Pi 4 uses a SoC called the Broadcom BCM2711. It has a quad-core ARM Cortex-A27 CPU with a clock speed of 1.8GHz, which is a major upgrade over the quad-core Cortex-A53 processor seen in the Raspberry Pi 3. Because the Cortex-A72 uses ARMv8 64-bit processing architecture, it can run 64-bit operating system and programs. This is a significant advancement over the raspberry Pi 3, which employs a 32-bit architecture, and it enables higher performance in a few applications that call for bigger quantities of memory or more difficult computations. The BCM2711’s Soc also houses a Graphic Processor Unit, a memory controller, a video processing unit, and a number of I/O interfaces like USB, Ethernet and SPI in addition to CPU. A hardware video decoder that supports the H.265, H.264, and MPEG-4 format is another feature of the BCM2711.\
