M.2 Key E PCI Express Slot J1100
The M.2 Key E PCI Express slot (J1100) used on the Open-X 8M development kit is a standard PC
style half-height card slot. It allows for external peripheral connectivity such as Wi-Fi / Bluetooth, or
PCIe based audio / video processors. Supported Card sizes are: 2230, 2245, 2260 and 2280.
Mounting holes are labelled on the top side of the PCB. In addition to being able to establish external
connectivity, the connector provides access to the PCIE2 interface, which is routed from the SOM.
