USB Connectors
The SBC-C90 board offers the possibility of connecting to many standard USB ports.
USB 3.1 Gen2 ports are carried to a double type-A USB 3.0 receptacle, CN12,
type Würth Elektronik p/n 692141030100 or equivalent.
More specifically, USB 3.1 port #1 is carried to the lower USB receptacle of
CN12, while USB 3.1 port #2 is carried to the upper USB receptacle of CN12.
Since this connector is a standard type receptacle, it can be connected to all types of USB 1.1
/ USB 2.0 / USB 3.0 devices using Standard-A USB 3.0 or USB 2.0 plugs.
For USB 3.0 connections it is mandatory the use of SuperSpeed certified cables, whose
SuperSpeed differential pairs are individually shielded inside the global cable
’
s external
shielding.
There are also two additional USB 2.0 ports (USB #0 and USB #3), which are hosted on a 9-
pin p2.54mm pin header, h= 6mm, type NELTRON p/n 2213SM-10G-E9-CR or equivalent,
with the pinout shown in the tables on the left (it is a common pinout for USB headers in PC
motherboards).
