The limit to USB power is from the fuses not so much the power adapter used, incoming power via USB-C or Vin appears limited to 2600mA. Also seen in the picture below, 500mA(USB port next to LAN), 900mA(USB port next to USB-C) fuses limit current on port’s 5vdc output. The USB ports on the GPIO are each(?) limited to 500mA. It might better be seen in the Schematic(PDF)
EDIT: It would be good to have one of the little USB Volt/Current gadgets to get a real time reading of the current demands of each of your USB devices. I have one on the way, I get curious about this.
I sometimes use a generic powered 4-port hub. I have noticed no problems using it with the Vim or USB connected devices, Sound card, Mouse, Thumb drive, etc. I have not used for SATA or IDE yet.
I’m going to use this hub to power the Board VIM (red connectors on the end). Then don’t need power supply. If you order from VIM and this hub, you can do without the power unit (partially offset by price hub). Ideally it would be nice if Khadas began to produce a smaller version of this hub (the size of the VIM and strengthen it from the bottom), on 8 regular ports and one for power VIM. With cable for power connection from the hub to the port VIN (which would have been free OTG port on the Pat VIM). To place USB connectors at parametru all lateral surfaces.
Didn’t try it yet but probably if you connect your vim to a powered hub, it will be powered through the usb port. No need for a extra power cable.
Just tried it, you can power it through a USB-port.
Yes, it can be powered through USB port, but if using other accessories plugged to on board USB ports(or GPIO) one should be mindful of 500mA and 900mA limits, depending on which USB port used for power.
maybe to provide with Khadas VIM an USB Serial Cable (like wetek did , at least with wetek openelec version), in this way many problems could be tracked better (like currently burning tool problem which already two guys have.
Or to plan this with VIM 2 . I am sure everyone can give few bucks more to have such cable at home!
I got my Vim from Gearbest in 2 weeks. GeekBuying is asking 30 days.
In any case that is not what I asked. My question was about GearBest, and will the fan be there any time soon?
