This learning package used demo versions and freeware products which are likely to have the publishing cost hardly anything. The printed circuit board with the USB interface, which unfortunately still internally mine works RS-232 protocols, built clean. The IC socket is used skillfully for the interconnection of the components. The description seems to me already usable. However, it is still expected minimum basics about processors. Even the programming should have a certain idea order to take advantage more than the supplied programs. Ready to use in my case was not the package. Instead of comfort along with the notebook running Windows 7 64 bit, the entire procedure is provisionally together with the old Windows XP PC. Programming may be so but no controller. For this you would have to build a different circuit itself. And this would only still require a parallel port on a PC. The learning package has thus considerable limits. And for more than to learn it can hardly be inserting. Unless you lot would modify itself in it. The included software makes a pretty together geschusterter impression. The word 'professional' would it probably barely attached. There are probably much better training for some extra cash. That is why the supposedly favorable acquisition has not made substantial returns.
