(Crosspost from the APU Forum)
Hello everyone in the forum.
In my current location DSL or cable internet bandwhich is quite limited, so I wana go by cellular connection. For that pupose I would like to know which bandwhich is supported by the PCIe connectors of the APU3a4 board. I know, that two of them support only USB, the other one mPCIe gen 2.
The question is: Which USB standard (only USB 2.0?) is supported on J14, J15a and how many gen2 lines are connected to the J16 connector?
Regarding to AMD, the GX-412TC supports up to 8 pci gen2 lanes and 2 USB 3.0 connectors (that are the external ones) as well as 8 USB 2.0 connectors. So my my concern is that J14 and J15 only support USB 2.0 speed? (https://www.amd.com/en/products/specifications/embedded)
I was looking for a new, recent 5G modem, because I don't want to buy outdaded hardware. It's ok if the max speed is not 100 % supported. Below are current cellular modems that are based on the M.2 formfactor. I would like to use them with an M.2 to mPCIe adapter, the last series of cellular modems do not use mPCIe anymore. They support up to 5,5 Gb/s, so it would be good to know if the APU has a fast enough connecion to use the components properly. In my area 5Gbit/s are not supported by cellular network, but it would be great, if I could use the modem at least with 250-1000 Mbit/s throughput to avoid a hardware bottleneck. Also, the Sierra and the Telit have onboard sim cardridges, so they would not rely on J14,J15 sim slots.
