Features of Raspberry Pi 3:

Processor:

Pi 3 is powered by Broadcom BCM2837 SoC (System on Chip) having a core ARM Cortex-A53 CPU. It runs at a clock speed of 1.3GHz. Pi 3 has resolution power up to 64-bit. This processor is based on ARMv8 Architecture and easily runs complex and sophisticated tasks and software in many demanding fields. Compared to the previous version, Raspberry Pi 2, it has better multitasking and jammies when executing applications.

However, the operational efficiency is still quite high so the performance can be applied to many areas such as embedded systems, DIY, etc. The processor includes fast video decoding acceleration features and well-implemented floating-point features which are useful for video applications or any sort of complex number computation.

Memory:

Raspberry Pi 3 comes with LPDDR2 SDRAM with a memory of 1 GB. It is quite low and average today but for the various applications like web access, programming, casual gaming, etc., it is quite practical. The 1 GB RAM allows the Raspberry Pi 3 to operate with various operating systems including the official Raspberry Pi OS, previously known as Raspbian, many other Linux distributions, retro gaming, and Windows IoT Core. it is ideal for portable and battery-powered projects.

GPU:

The Raspberry Pi 3 has Broadcom VideoCore IV GPU, specially designed for media applications. It has various applications in many demanding fields like video streaming, running video games, or rendering graphical interfaces.

As such, the Raspberry Pi 3 is also believed to effectively serve in contexts that require a display, for instance, media center usage, web browsing, and graphical programming projects.

Raspberry Pi 3 I/O Ports:

USB Ports:

It contains are 4 USB ports used to connect devices like keyboard, mouse, external storage devices, and sensors.

HDMI Port:

Pi 3 contains an HDMI port that provides 1080p video output. It is ideal in applications including media-center setups, digital signage, or interactive projects.

3.5mm Audio/Video Jack:

It has a 3.5mm jack which efficiently gives audio and video signals. It’s a useful feature for DIY projects that require basic audio or video output.

Camera Modules:

Camera serial interface (CSI): 

The CSI interface makes it possible to attach the official Raspberry Pi camera module. This is helpful in some use cases including security cameras, time-lapse photography, and certain computer vision uses.

Display Serial Interface (DSI): 

The DSI interface also allows the user to connect an official Raspberry Pi touchscreen display for projects that involve interactivity, maybe kiosks or portable computing devices.

Power supply:

It requires 5V to operate the device using a microSD card slot. It is efficient, to say the least, with reasonable power consumption given its abilities. Furthermore, it is highly efficient making it fit for all kinds of projects where continuous use is needed like home automation systems, servers, and other embedded-type systems.

When it comes to Embedded projects, Power management is one of the most important factors in designing the system, and here the power is managed quite efficiently as the Raspberry Pi 3 can be used with a power bank and quite a low power setup.

Storage:

The Raspberry Pi 3 does not include any real storage onboard. This computer instead gets its operative system from a microSD card that acts as a booting device. With this storage approach, users can easily upgrade and personalize their devices through the simple process of SD cards to change operating systems or add storage capacity.

It is recommended to use high-speed PSD (micro SD cards) preferably with a class 10 rating or higher, when performing tasks that are intense or transfer large amounts of data as these devices will ensure good performance.

Operating Systems and Software:

The Raspberry Pi 3 offers many operating systems including:

● Other Linux systems such as Ubuntu and Arch Linux are also available; for those looking to use the Pi as a standard desktop computer, these systems provide a more conventional desktop or server interface.

● Windows IoT core is a Windows version that is suitable for IOT devices. It is a lightweight and power-efficient OS that is ideal for ‘embedded’ devices such as the Raspberry Pi.

● RetroPie, LibreELEC (and other such specific versions) OS have the capability of changing Pi into a media player a gaming console, or a home theater system.
