The Rasberry Pi was previously known as a mini-computer for hobbyists. With version 2 (incl. The components contained in this package), this calculator is with NOOBS and Raspbian (a Linux derivative) installed can be used immediately and without soldering with a few simple steps in the transparent housing. All very well matched and on the supplied memory card NOOBS was already installed. The WLAN module was from the beginning very good! Highly recommended!
