Updated/Summary Board Walk-thru based on conversations..
SoC is Atom E3845 (1.9GHz, 4 cores) - the giveaway is the HDMI and USB3 ports, which are native to that chip, along with the two SATA ports (one is mSATA, which is situation between the 5GHz m-PCIe card and the 2.4GHz m-PCIe card.
Atom E-series has the benefit of AES-NI, unlike Baytrail-D(J-series) or Baytrail-M(N-Series) - so this is a good choice - good choice, cost efficient and relatively stout - one must ask about that HDMI port, as this could be interesting to use in the future...
2.4GHz - confirmed it is QC-Atheros, same with 5GHz. These are running off the PCI-e lanes (one each), with the other lane going to a 1GBe Intel NIC - lots of bandwidth here.
With regards to the WiFi, N300 in 2.4GHz is more than sufficient, 99 percent of 2.4GHz clients are two streams or less, so no need to go further - 3*3:3 on the 5GHz side, also the right call - no need for more than that...
(it's doesn't fit within the "bigger numbers are better" marketing charts, but this is a sound engineering decision, and allows Roqos to invest more in other areas with no hit to WiFI performance)
Broadcom gets the win for the GBe switch, and again, good choice...
8GB mSATA for internal resources, plus the SATA2 port is populated (just the data side, no power header, but that's easy to solve off the circuitboard)
Then we still have the USB external port if additional storage is needed.
Other comments - looks like we have a UART available - and a couple of USB headers (look to the right of the CPU and down in the lower left hand corner)...
This could be a fun little hacker board actually... and a very stout Home/Small Business Router.
There's enough capability in here to function in pretty much any role within a Cloud/Software Defined Network environment. This could be used as a router, a NAS, a settop box (good reason for the HDMI port) - so it's basically a universal box, and the software components, along with HW choices, it is a good platform to work with. With CoreBoot, it's fairly open, and I'm willing to bet it's not running OpenWRT
(even though it could) - gut tells me that Debian or RedHat could easily fit on there, and run very nicely, and still be fanless and low power draw.
(removed BOM estimate, as it's not relevant, but it's a scalable design with regards to storage and memory)
This is not a cheap build - high quality components across the board - a good example is the CPU voltage regulators - take a look at them, they're not the typical ESR caps, these are much higher quality, with longer lifespan and better performance in high load/high temp conditions.
From a device perspective, these guys absolutely got it right... If the same level of care and attention is there at the software and services layer, then this is a winner!
Well Done!
