"The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does."

More GPIO.
The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
More USB.
We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
Micro SD.
The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
Lower power consumption.
By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
Better audio.
The audio circuit incorporates a dedicated low-noise power supply.
Neater form factor.
We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes
A 1.2GHz 64-bit quad-core ARMv8 CPU
802.11n Wireless LAN
Bluetooth 4.1
Bluetooth Low Energy (BLE)
 
Like the Pi 2, it also has:
1GB RAM
4 USB ports
40 GPIO pins
Full HDMI port
Ethernet port
Combined 3.5mm audio jack and composite video
Camera interface (CSI)
Display interface (DSI)
Micro SD card slot (now push-pull rather than push-push)
VideoCore IV 3D graphics core
   
bananapi orangepi

Banana Pi is a single-board computer and it targets to be a cheap, small and flexible enough computer for daily life.  Built with ARM Cortex-A7 Dual-core CPU and Mali400MP2 GPU, and open source software.

What’s Orange Pi Plus2?
 
It’s an open-source single-board computer. It can run Android 4.4 , Ubuntu, Debian, Rasberry Pi Image, it uses the AllWinner H3 SoC, and has 2GB DDR3 SDRAM
 
rbZero nanopi
 
The Raspberry Pi Zero is half the size of a Model A+, with twice the utility. A tiny Raspberry Pi that’s affordable enough for any project!
 
1Ghz, Single-core CPU
512MB RAM
Mini HDMI and USB On-The-Go ports
Micro USB power
HAT-compatible 40-pin header
Composite video and reset headers
 
 
The NanoPi is a low power consumption, Samsung S3C2451 based ARM SOC that FriendlyARM developed for Linux hackers, Hobby makers and hobbyists. Its size is only half of the Raspberry Pi(RPi) and its GPIO pin is compatible with the RPi’s. The NanoPi integrates both the WiFi and Bluetooth 4.0,and has MiPi sockets for cameras and LCDs.
