From the project
Open source eGPU dock for ROG Ally and ROG Flow
XG Mobile Dock ============== This open source hardware allows you to connect any PCIe card to an ASUS ROG device with the XG Mobile connector.
The standard variant is a drop-in replacement PCB for the [XG Station Pro Thunderbolt 3 eGPU dock][1]. It contains a built in USB 3.1 Gen 2 hub and a USB PD charger.
The lite variant is a standalone board that is compatible in dimensions with the [ADT-UT3G][6]. It requires a standard ATX power supply and passes through the USB to an external port.
