USB Ports¶
mPCIe MiniExpressCard¶
The Arrakis MK3 is equipped with four mPCIe connectors, enhancing its flexibility and connectivity options:
Full-size mPCIe Slots:
Primary Slot: Typically preoccupied with an mSATA SSD, which is not readily available for other uses.
Secondary Slot: Facilitates connections for USB, mSATA, and PCIe interfaces, offering versatile usage.
Additional Full-size mPCIe Slots:
These slots are configurable based on specific requirements, available either on demand or with a pre-installed 4G modem. Generally, one of these is dedicated to the 4G modem, limiting the other for USB device compatibility.
