USB ports
The UDOO VISION board offers the possibility of connecting to many standard USB
ports.
USB 3.0 ports are carried to a double type-A USB 3.0 receptacle, CN17, type Winning
p/n WDU3R-18F1B4PBUN3 or equivalent.
More specifically, USB 3.0 port #0 is carried to the upper USB receptacle of CN17,
while USB 3.0 port #1 is carried to the lower USB receptacle of CN17
There are also two additional USB 2.0 ports (USB #4 and USB #5), which are hosted
on a 9-pin p2.54mm pin header, h= 6mm, type NELTRON p/n 2213S-10G-E9 or
equivalent, with the pinout shown in the tables on the left (it is a common pinout for USB
headers in PC motherboards).
All USB ports voltages (+5VUSBx) are derived from +5V_ALW standby voltages. This means that the
ports can be powered also when the OS is in Suspend-to-RAM (S3) state in order to support (if enabled)
e the Wake-Up on USB functionality.
