POWERING THE ULTRAUSB HUB
There are two ways to power the UltraUSB Hub. You can power the hub straight off the host device or externally power
with a 5V supply. The maximum downstream current is 500mA per port when the hub is externally powered. When the
hub is not externally powered, then the maximum downstream current is host dependent.
2.3.1
POWERING OFF THE HOST DEVICE
The UltraUSB Hub can operate without the use of external power. However, the maximum downstream current will be
dependent on the electrical characteristics of the host device. If your host device is powering devices such as an UVC
Camera, it is recommended to use an external power source.
2.3.2
POWERING WITH AN EXPANSION /CONTROL HUB
Using the JST-PH 2-pin to 3-
pin 0.1" (PWM/Dupont) Connector Cable, connect the power cable to the “+5V POWER” ports
.
2.3.3
POWERING WITH A 5V EXTERNAL BATTERY PACK
Using the JST-PH 2-pin to USB-A Cable, connect the power cable to a USB-A port on a 5V external battery pack.
