Your first link is a comparison between the Arduino Uno and the Sparkfun Redboard. The Redboard is functionally identical to an Uno in that it is nothing more than an AVR microcontroller board. The reason why you would choose it over the Uno is to have a more modern and slightly cheaper board while supporting Sparkfun.
The second link you posted is for an Arduino Yun which takes the basic Arduino platform and adds a much more powerful MIPS core running Linux to offload all the networking tasks from the AVR microcontroller. The Yun is not[/b] directly comparable to the Sparkfun Redboard. -Bill
Thank you for your replies. Sorry. Need more information:
SparkFun uses also powerful MIPS core running Linux to offload all the networking tasks from the AVR microcontroller?
Is it possible to receive required components to go with the Sparkfun in application Push button?
As we know there are many kits offered by Arduino like: Arduino Inventor’s Kit, Arduino Sidekick Basic, Arduino Beginner Parts Kit. Which kit is preferred by Sparfun development to measure, connect (wires), power supply…
The Sparkfun Redboard does not have a MIPS core. It is functionally identical to the Arduino Uno.
Remember that “Sparkfun” is the name of the company, not an actual product. You can order an Arduino Yun (more expensive than Arduino Uno and Sparkfun Redboard) and all the supporting componentry needed for the tutorial directly from Sparkfun.
Sparkfun has a few kits available to suit different needs. You need to read their descriptions to see what they come with and determine which one is best for you.
