This device is a USB 2.0 hub. This is a multi-TT hub: it performs better than a regular single-TT hub when several USB 1.1 devices are connected to it. It is tiny (42x28mm) and its size can even be cut down to 36x20mm, most probably one of the smallest you can find...

It is designed for DIY applications, for those who want to connect several USB devices in a tiny space. This hub does not have connectors for slave USB devices, but solder pads: you can solder wires directly on it. Yoctopuce modules can be fixed on it using screws and spacers. This hub also supports external power supply, and automatically switches from usb power to external power when available.

Hi, this hub supports PPPS (Per-Port Power Switching)? The features description of Microchip's USB2514B says there's a some power control options ("Full power management with individual or ganged power control of each downstream port"), but is not clear.

@marck: nope, like with most USB hubs available on the market, the "smart" power management part is not implemented on the Micro-USB-Hub-v2. The only power management feature available is automatic switching between external and BUS power.

Hi. What is the operating temperature range? We want to use it for astronomical applications and a lower limit of -10░C is desirable.

4 - martinm (Yocto-Team)Saturday,december 17,2016 14H10

@drakonte: -30..85░C but you'll have to keep it away from condensation and ice.

Is this in stock?

6 - martinm (Yocto-Team)Saturday,november 20,2021 16H40

@carl101: Yes, unless clearly stated otherwise, all Yoctopuce products can be shipped within 2 business days.

Hi I purchased one of these recently but would like to know if I can use it with 2 devices that both have USB-C ports. 1 is an Arduino Portenta H7 and the other is a webcam. Thank you.

@lsi8: As a general rule it's a bad idea because a USB-C device is likely to use USB 3, the Micro-USB-Hub-V2 is only USB 2.0 Moreover, depending on how the device USB wiring and implementation is done, it might not work. If you want to be sure, give it a try with a USB-A to USB-C cable plugged in a USB 2.0 host port.

Hi. Would the device allow simultaneous use of Yocto-thermocouple and Yocto-Light-Vn, so to collect data from the two sensors at the same time?
Thank you.

10 - martinm (Yocto-Team)Friday,march 11,2022 17H10

@atriolo: of course since it's a regular USB 2.0 Hub. Actually, if your goal is just to use a Yocto-Thermocouple and a Yocto-Light from the same USB port, then any USB hub will do. If you have two USB ports available on your computer, then you won't even need a USB hub.

Hello! Is there any chance we could order this with the picoblade connectors already attached? We're going to need a dozen, would love to avoid the soldering of 192 points...

12 - martinm (Yocto-Team)Thursday,december 01,2022 14H05

@James Haley : Yes, contact the Yoctopuce support.

Hi, whats new on the Micro-USB-Hub-V2 Rev. D?
What about the "Bridge to force Ext. Power"
It is not described in the datasheet.

14 - martinm (Yocto-Team)Monday,february 13,2023 17H19

@gampt: when "Bridge to force Ext. Power" contacts are bridged together, the hub will only use external power instead of automatically choosing best power source between external power and USB bus.

Yoctopuce, get your stuff connected.
