You will probably have to come up with a separate 5V power source for the USB Host port.
The Pocket Beagle has three power inputs that will power the CPU: Vin, USB-VIN and the battery input. None of these back power the other inputs. Any of the three inputs may be switched to the VOUT line, but when on LiPo battery, this will only be 3.2 to 4.2 Volts, which is not within USB spec for Vbus. So, if you are running off of 4V LIPO battery, there is no on-board source of 5 Volts for the USB ports. You may have to provide your own boost converter or other 5V source. --- Graham == On Friday, November 10, 2017 at 9:30:35 AM UTC-6, [email protected] wrote: > > I, too, am curious about how to do this, while using the on-board USB jack > in host mode (maybe with an OTG adapter and a wi-fi dongle?).
