It is no secret that Raspberry Pi is a huge success. It is a microcomputer that is almost the size of your palm. It’s ease of access, user-friendliness, multiple GPIO pins and price has made the foundation to sell over eight million units in last four years. Let us take a look at Raspberry Pi 3 specifications –
|Raspberry Pi 2||Raspberry Pi 3|
|CPU||900 MHz quad-core ARM cortex-A7 CPU (Broadcom)||1.2GHz quad-core ARM cortex-A53 CPU (Broadcom)|
|GPU||Videocore IV||Videocore IV|
|Memory||1 GB||1 GB|
|Storage||microSD card slot||microSD card slot|
|Connectivity||4 USB, HDMI, Ethernet, 3.5mm audio jack, Wi-Fi, Bluetooth||4 USB, HDMI, Ethernet, 3.5mm audio jack|
|OS||Linux, Windows 10 IoT core||Linux, Windows 10 IoT core|
The System on a Chip (SoC) from Broadcom is the black chip located in the middle of Pi. Below SoC, you will find HDMI port and to its right, you will find USB ports and Ethernet Port.
GPIO pins are available on the top edge. Along the side opposite to USB ports, you will find microSD card slot. Power Supply, Camera port and audio jack are alongside to HDMI port.
Wireless radio – The Broadcom BCM43438 chip provides 2.4GHz 802.11n wireless LAN, Bluetooth Low Energy, and Bluetooth 4.1 Classic radio support.
Antenna – You don’t need to connect external Antenna, It has already been soldered into the board. As they say, it is capable enough to pick up Wireless LAN signals and Bluetooth signals even through walls!
You get the classic 40 GPIO pins along with this board too.
Raspberry Pi 3 Software:
Keeping this section simple, the choice OS for Raspberry Pi is Debian based Raspbian. Installing Raspbian is simple and there are lots of tutorials available online.
Raspberry Pi 3 Performance:
Theoretically, since Pi 3 is clocked 1.2Ghz, so its performance is increased 33% from the start. Secondly, Cortex-A53 is nearly 50% faster than the previous cortex-A7. Which makes Pi 3 40-50% faster than Pi 2.
With all these developments, Raspberry Pi 3 has come very close to a real desktop replacement. However, that is not its mission. Raspberry Pi 3 is for hobbyist and educators and for that its performance is impressive. It comes pre-installed with Python 3 IDLE and many other tools. You can also use tools like OpenCV, languages like C, C++, java Golang, etc.
Some stuff you can make:
Following are simple examples that will help a new hobbyist to get ideas –
- Raspberry Twitter Bot (Tweet Through Raspberry Pi)
- Internet of Things
- Drones, Quadcopters, Rovers and much more.
Raspberry Pi 3: Final opinion
The Raspberry Pi foundation has stayed true to its mission to deliver best microcomputers at affordable prices. With built-in Wi-Fi and Bluetooth and also a better CPU, we can say that Pi 3 is a worthy successor of the previous boards.
So what are you waiting for? Upgrade to Pi 3. If you are new to this field, get started now!
