A USB 2.0 cable, type A-micro B
USB 2.0 connectors exist in three sizes: the "standard" size that you probably use to connect your
printer, the very common mini size to connect small devices, and finally the micro size often used to
connect mobile phones, as long as they do not exhibit an apple logo. All USB modules manufactured
by Yoctopuce use micro size connectors.
The most common USB 2.0 connectors: A, B, Mini B, Micro A, Micro B

To connect your Yocto-Display module to a computer, you need a USB 2.0 cable of type A-micro B.
The price of this cable may vary a lot depending on the source, look for it under the name
USB 2.0 A
to micro B Data cable
. Make sure not to buy a simple USB charging cable without data connectivity.
The correct type of cable is available on the Yoctopuce shop.
You must plug in your Yocto-Display module with a USB 2.0 cable of type A - micro B
If you insert a USB hub between the computer and the Yocto-Display module, make sure to take into
account the USB current limits. If you do not, be prepared to face unstable behaviors and
unpredictable failures. You can find more details on this topic in the chapter about assembly and
connections.

recognized it. It is time to make it work.

succinct interface to configure your modules and to test their basic functions. You access this
interface with a simple web browser

Virtual Hub
software in a command line, open your
preferred web browser and enter the URL
