6.2. USB3.0 (Port 2) Sharing
The
USB3.0 Port 2
of the SMARC module is shared by following features:
-
USB3.0 Upper Port
of the
J24
- Dual USB 2.0 Type-A connector at the I/O shield
-
USB Type-C
connector
J26
at the I/O shield
Note: It is not possible to use both features at the same time.
USB3.0 Port 2 Switch-Modification Instruction
To switch the USB3.0 Port 2 to J24 or to J26 see the
“USB3.0-P2 Shared Components Modification Table”
below.
Use
