Raspberry Pi Model B+ Guide

Raspberry Pi Model B+ Guide:

After Four years from  the launch of the first Raspberry Pi, the Raspberry Pi Foundation came up with the third generation of Pi series that is Raspberry Pi 3 Model B. Raspberry Pi 3 replaced the Pi 2 in the current scenario,here we will go through what’s new in terms of features,appearance and specifications, and will also see a quick comparison of the new Raspberry Pi 3 with the Raspberry Pi 2 and B+ versions of it.

What’s new in Raspberry Pi Model B+ ?

  • Broadcom BCM2837, a quad-core 1.2GHz 64-bit ARMv8-A Cortex-A53 Processor powered Single Board Computer
  • It is provided with 1GB RAM for the compact running of bigger and more powerful applications.
  • 3rd party add-on boards are also supported as the extension to this .
  • Fully HAT (Hardware Attached on Top) compatible.
  • 40pin extended GPIO to enhance your “real world” projects. GPIO is 100% compatible with the Model B+ and A+ boards. First 26 pins are identical to the Model A and Model B boards to provide full backward compatibility across all boards.
  • Connect a Raspberry Pi camera and touch screen display
  • Stream and watch Hi-definition video output at 1080P
  • Supports Video Core clocked at 400MHz for video processing and the 3D graphics processor running at 300MHz .
  • Micro SD slot for storing information and loading your operating systems.
  • Advanced power management: You can provide up to 5V 3 AMP(recommended) via micro USB port by using adapter .
  • 10/100 Ethernet Port to quickly connect the Raspberry Pi to the Internet
  • Combined 4-pole jack for connecting your stereo audio out and composite video out.
  • Have on board Wi-Fi and Bluetooth connectivity. The WiFi is compatible with 2.4GHz 802.11 b/g/n networks and the Bluetooth 4.1 supports BLE (Bluetooth Low Energy) both are supplied by the BCM43438 ( This feature is not available in its previous version)

Quick Comparison : 

The combined WiFi/Bluetooth ceramic antenna package sits just above the DSI connector (the white rectangle) which means that the run header has moved across between the GPIO pins and the USB jacks like on the Pi Zero. The power and activity LEDs have also moved from top left to bottom left, again to accommodate the WiFi/Bluetooth, which may be a problem if your case uses light guides.

GPIO Pins of Pi 3 :

This GPIO Pinout is designed to be both a quick and interactive reference to the Raspberry Pi GPIO pins, plus a comprehensive guide to your Raspberry Pi’s GPIO interfaces. It also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs

Rasbperry Pi 3  Connectivity :

In Pi 3 we have four USB 2.0 ports (3.0 is above its pay grade), a Ethernet connector, full-size HDMI port and a micro-SD slot. This isn’t an ‘extra’ with a Pi. Whatever memory card you use acts as the hard drive here. It has WiFi and Bluetooth, where you’d need to use USB adapters to add that to a Pi 2. This is a massive benefit if you want to use the Pi as a mini media center.
