I finally get Raspberry Pi 3 for experiments and further projects! Yaay! 🙂 First of all lets understand the difference between Pi 2 and Pi 3. It will help us in knowing why I opted for Pi 3 and advantages over Pi 2.
If you have missed my previous tutorials series go back and first build a basic robot with Pi. Here is the step by step guide:
Step by Step Tutorial to build basic Pi Robot
- Understanding Raspberry PI and Robotics
- Assembling Raspberry PI Robot and all electronics
- Programming Raspberry PI Robot with Python
- Final Raspberry PI robot in Action
Pi 3 is best suited for Robotics tutorials as it has inbuilt WIFI and Bluetooth. I had to purchase separate dongles and packages to make everything work.
Raspberry Pi 3 Specifications
First let’s understand Pi 3 main Specifications:
The Raspberry Pi 3 is the third-generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016.
- Quad Core 1.2GHz Broadcom BCM2837 64bit CPU
- 1GB RAM
- BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board
- 40-pin extended GPIO
- 4 USB 2 ports
- 4 Pole stereo output and composite video port
- Full size HDMI
- CSI camera port for connecting a Raspberry Pi camera
- DSI display port for connecting a Raspberry Pi touchscreen display
- Micro SD port for loading your operating system and storing data
- Upgraded switched Micro USB power source up to 2.5A
Raspberry Pi 2 Vs Raspberry Pi 3
Below are the major differences between Pi 2 and Pi 3:
|Model||Pi 3||Pi 2|
|Characteristics||Performance WIFI/Bluetooth/Ethernet||Performance Ethernet|
|Processor||BCM2837 quad core linux ARMv7 – 64 bit CPU||BCM2836 quad core linux ARMv7 – 32 bit CPU|
|Typical Power||2.5W(upto 6.5W)||2.5W(upto 4.1W)|
I will use Raspberry Pi 3 for all my future projects 🙂 Stay tuned. Next project will be to build a Raspberry Pi Robot controlled by Android Mobile App.
