4.16GPIO

The COM Express module provides four general purpose outputs and four general purpose inputs.

The GPIs have PullUp resistors and are routed to a dip switch (SW1103). With the dip switch the GPIs can be connected to ground. The assignment GPI – switch – level is printed on the PCB.

If the PullUp resistors are not populated, you can switch LPC_SMI# or HWM_SMI# to GPI0, GPI1, GPI2 or GPI3 with jumper JP1101.

The GPOs are connected to LEDs for optically status display.
