USB2.0 Hub Four way expansion for your ARM board (or an PC). This hub is powered by the host. The 5 volt power to a FriendlyARM board passes to the USB port without regulation, so the USB will not load the on-board regulators. The PSU's that come with our kits are rated 2 amps, which leaves plenty for the USB connections. The photo below has a console window open on the Qtopia desktop. The console was opened with the mouse and Linux commands are entered with the keyboard. It's a total workstation! The hub looks a little awkward attached to the little Mini35, but it was hard to see a good way to photograph, and it works great.
