Are you looking for a free USB device? Don't order this one, it is useless: it only includes a button, a blue localization LED and a green test LED. However free, it is really a useless device. Don't order it.
On the other hand, if you are interested in testing our programming API and make sure that you will be able to complete your project using Yoctopuce modules, then you should order this Yocto-Demo! Make your tests without any risk indeed, since this module is given for free, without even any shipping cost.
However free, these devices do not grow on trees. Therefore, there is a limited stock available every day. And of course, we will only ship one item per person/address.
This product is not shipping for now. For more information, have a look at the blog article about the Yocto-Demo.
USB cables and enclosure to be ordered separately.
