GPIO
The COM.0 Rev 2.0 Type 10 standard specification allows for optional SDIO signals to be
carried over the GPIO pins. On the nanoX-TC, the output mode is set to either SDIO or GPIO
by BIOS setup. The nanoX-BASE has no special setting for this and will either output the
GPIO signals to the GPIO header or the SDIO signals to the standard SDIO socket.
If SDIO mode is selected in BIOS, the GPIO pins below cannot be used.

AIDI Demo Program
- GPIO Tab
The AIDI Demo Program displays
current GPI or GPO status and
allows reading of GPI and writing
to GPO.
The table above links logical port
numbers in AIDI to physical port
numbers on the COM Express
board-to-board connector.
For boards that support
multi-
direction
the “SetDirection”
button can configure the port for
either GPI or GPO
