## Notes related to M.2 Card
|
|
The M.2 devices installed in Helios64 is configured as sharing devices with SATA Port 1.
|
|
Therefore if you install M.2 SATA module, you will not be able to access the SATA Port 1.
|
|
In another case, if you use the M.2 USB module, the SATA Port 1 still accessible from the system.
|
|
|
|
The USB bus is connected to the [OHCI/EHCI Host 0](/helios64/usb/#usb-on-helios64).
|
|
|
|
The M.2 socket in the Helios64 board may NOT support USB modem (WWAN), because the USB modem requires the SIM Card connection and another signal.
