Edge Gateway I/O module GPIO mapping
The GPIOs on the external I/O Module for the Edge Gateway are behind the PIC microcontroller. The PIC microcontroller is exposed
to the host system and to the host OS as a USB-HID device. Software applications developed to communicate with the GPIOs may
use the protocol dened in the above set of references to communicate with the GPIO modules.
Edge Gateway I/O module PCIe expansion mapping
The PCIe slot on the external I/O module for the Edge Gateway is driven directly from the host PCIe bus. Since PCIe expansion is
generic, there are no PCIe device-specic drivers integrated into the Windows 10 IoT Enterprise LTSB OS image. If a specic PCIe
card is to be used on this slot, contact the vendor of that PCIe card to verify if they have the required drivers for Windows 10 IoT
Enterprise LTSB.
