8: Down port 3 2.1. Double power supply Your Micro-USB-Hub-V2 is able to manage a double power supply. You can simply connect the Micro-USB-Hub-V2 as is to your computer, and your computer is then responsible to provide the power necessary to supply the whole. In this case, be aware that a USB port does not supply more than 500mA, theoretically. -

2000mA, it actually works in every day life, and seldom makes hardware damage. What you should remember: if you connect Yoctopuce modules through one, or more, USB hub without external power supply, you have no safe-guard and you depend entirely on your computer manufacturer attention to provide as much current as possible on the USB ports, and to detect overloads before they lead to problems or to hardware damages. -
Page 9: Limitations
2.5. Limitations Like all hubs on the market, the Micro-USB-Hub-V2 declares to the computer that it is self-supplied, whether there is an active external power supply or not. Doing so prevents the computer to which the hub is connected from deciding to limit the power of the peripherals that are connected to it to 100mA for each port, which would generally render them unusable. - Page 10 www.yoctopuce.com...

Page 11: Interconnection
The Micro-USB-Hub-V2 is not equipped with connectors on the down ports: you must directly solder wires or connectors on the transversal contacts designed for this. This considerably reduces the space needed compared to a USB socket and the plug that fits in it. With the Micro-USB-Hub-V2, there are numerous connection methods. -

3.3. Direct soldering on the up port If you believe that the Micro-USB-Hub-V2 takes too much room in your project, you can eliminate the up port connector, and solder a USB cable instead: cut the printed circuit with the help of a good pincer and, if needed, sandpaper the protruding parts. -
Page 13: Minimal Size
3.4. Minimal size It is possible to lower the size of the Micro-USB-Hub-V2 down to 20x36mmmm by cutting one of its ends. This allows you to slip it into the most tiny locations, but you will loose the the possibility to screw four Yoctopuce modules on it. - Page 14 www.yoctopuce.com...
