This is an introduction of Raspberry Pi 3 Model B. We will explore what Raspberry Pi 3 has to offer in terms of its features and performance. I would like to introduce Raspberry Pi as a world’s most inexpensive and powerful Single Board Computer. Ever since the launch of Raspberry Pi from 2012, we have seen several version of it. This is world’s cheapest microprocessor unit specially built for learner and makers. We can easily learn how software and hardware work together without been worrying about damage/cost. We can buy Raspberry Pi board with just somewhere around 35$. The cost of Pi allows newbies to celebrate mistakes and learn most out of it. Also Raspberry Pi has a huge community and plenty of online resources which make learning smooth.
If you have previously used Arduino (another famous inexpensive computer) and now want to explore Raspberry Pi. The Raspberry Pi is a single board computer with Microprocessor whereas Arduino is considered as Microcontroller unit. The Raspberry Pi can run an OS (Linux Distribution) and also consumes more power. Since Arduino is microcontroller device it has no operating system and can only run a single program or sketch. The bottom line is when comes to control anything I would recommend Arduino. We might use Raspberry Pi for anything where we want a fully functional cheap computer. Raspberry Pi also becomes a good choice for building IOT (Internet of Things) Applications.
Raspberry Pi 3 Model B Features
CPU: Raspberry Pi 3 uses Broadcom BCM2837 SOC 64-bit quad-core ARM Cortex A53 (ARMv8 CPU) with 512KB shared L2 cache.
Memory: Provided with 1 GB of RAM
Wi-Fi Support: 802.11n Wireless LAN
Bluetooth: Supports Bluetooth 4.1 Bluetooth Low Energy (BLE)
USB Ports: 4-USB ports which allow attaching four different USB devices like keyboard, mouse, etc.
Ethernet Port: Standard Ethernet port to quickly setup and access internet. This can be very useful when we want to setup raspberry pi for the first time without a monitor.
GPIO Pins: Raspberry Pi 3 supports 40 GPIO Pins General Purpose Input Output. These digital input/output pins can be used to drive LED, Switches, and Sensors etc.
Full HDMI Port: Support HDMI port (High-Definition Multimedia Interface) which can be used to quickly connect raspberry pi to HDMI Monitor. With HDMI Cable and Monitor we can add Screen to Raspberry Pi.
Micro SD card slot: The Micro SD Card will hold the operating system which will boot while we power on Raspberry Pi 3. In next tutorial, we will learn how to setup and prepare SD card with Raspbian OS.
Audio/Video: Combined 3.5mm audio jack and composite video
Display interface (DSI): enable us to interface Display Module
Camera interface (CSI): enable us to interface Camera Module
Graphics Support: VideoCore IV 3D graphics core for advance graphics capabilities.
This is it for the introduction of Raspberry Pi 3 Model B. In next tutorial, we will learn how to prepare SD Card with Raspbian OS. Also, we will learn how one can boot raspberry pi for first time and setup for programming. There are endless projects that can be built around Raspberry Pi. We will explore them as we move along with this Raspberry Pi 3 tutorial series. Thank you.
