It appears that only one PCIe 3.0 lane is wired through to each of the four NVMe m.2 slots, limiting the benefit of higher-performance drives. See the first-page block diagram of this schematic PDF for the NAS breakout board:

Is anyone successfully using a Wifi or other network card in the shorter, A/E-keyed m.2 2230 slot of a NanoPC-T6 LTS, the newer variant of this board that's replaced its mini-PCI LTE-modem slot with extra USB ports? I want to add a third wired Ethernet port to mine, and so bought an i210-based 1Gbps...

If you check posted schematics, the SIM socket on a NanoPC-T6 (do R6S & R6C have SIM slots at all?) is wired only to the miniPCIe slot on top, not to either m.2 slot underneath. So, you wouldn't be able to use it as a native m.2 device. Certain miniPCIe-to-m.2 adapter boards may work, but probab...

The $20 metal case sold by FriendlyElec for the NanoPC-T6 does work this way - one machined or extruded piece of aluminum, with thick metal up top, some exterior grooves for greater surface area, and an extension inside that presses perfectly against the CPU/SoC, with a supplied thermal pad. In my l...
