Gigabyte SA-SBCAP3350 puts formidable power on a single board

When you hear "single-board computer," you probably think of a Raspberry Pi, HardKernel ODroid, or BeagleBone. You probably don't think of a pocket-sized PC with a 1.6 GHz Intel chip, dual Gigabit Ethernet connections, dual 6Gbps SATA ports, and USB 3.0. Gigabyte's new SA-SBCAP3350 single-board computer has all that and more, and it's still smaller than a Mini-STX PC.

The SoC in question is the Apollo Lake-family Celeron N3350. That's a dual-core part with a 1.1 GHz base clock and a nominal Turbo Boost to 2.4 GHz, although Gigabyte lists its clock speed at just 1.6 GHz. Our take is that it's probably been detuned to hit a lower "scenario design power." Builders are supposed to cool the chip by mating the massive metal plate on the bottom of the SBC to a heatsink or the exterior of an industrial chassis, but we figure you could probably just blow a fan over the plate to cool the 4W SoC.

The Celeron is hooked up to a single SO-DIMM socket that supports DDR3L modules as large as 8GB and as fast as 1866 MT/s. Video duties are also handled by the Celeron, and output comes by way of a VGA port, an HDMI 1.4 connection, or through an LVDS header for directly connecting an LCD. Analog audio passes through a 3.5mm headphone-and-microphone combo jack supplied by a Realtek ALC255 codec. Realtek also powers both of the on-board gigabit Ethernet connections.

Sadly, neither of those two sockets on-board are for M.2 drives. One is a half-size Mini-PCIe slot that is just ripe for a Wi-Fi adapter, and the other is an old-school Mini-SATA port. If you can't find an mSATA drive, you can hook up storage to the two on-board SATA ports. The board supplies power for the SATA devices, too. On the back of the board are two USB 3.0 ports, but you can hook up headers for four more USB 2.0 ports if need be.

Speaking of headers, this thing has a plethora of tiny pins to provide all of the low-level I/O that makers love to muck with. Besides the usual front panel header and speaker headers, there's an LPT or GPIO header, an I2C connector, an SMBUS connector, and four serial port headers. There's also an onboard header to connect a fan should your chassis need one.

All in all, this seems like an incredibly full-featured machine for the size. The GA-SBCAP3350 measures just 5.7" x 4" (14.6 x 10.2 cm). That's pretty big for a single-board computer, but it's downright tiny for a Windows-capable PC with all these capabilities. Gigabyte hasn't announced pricing or availabilty for the GA-SBCAP3350 yet. Thanks to FanlessTech for the tip.

    Man, my boss and I would’ve killed to have an SBC like that, back in 2000/2001. I was working at a startup company that went tits up, since we trying to develop a low cost alternative to the +$10,000 Blusocket gateway controllers. The SBCs we found were severely lacking, and we just couldn’t make it work. We were using Linux instead of Windows, but having the ability to use an HDD, instead of being limited to 64MB CF would’ve been a god send (especially since the blusockets themselves were using 500MB HDDs running linux anyway.

    Oh well. C’est la vie.

    EDIT: For comparisons sake, the SBC the higher ups wanted to go with, had a miserly 64 or 128MB soldered onto the board, and the CPU was either an AMD Geode, or whatever the part was called before AMD bought it, and renamed it Geode. A 1.1GHz dual core CPU would’ve run rings around it.

    EDIT 2: Hell, now that I think about it, a Raspberry Pi 3 would’ve been a huge step up, too.

    If that puny Celeron has ‘formidable’ power, I wonder what adjective to use to describe real desktop processors like Ryzen, i5/i7 and even the underappreciated FX series.

      I’d love to see some benchmarks of this vs the Odroid-C2 or XU4.

      If anyone gets one of these, contact me and we’ll arrange something.

      I think it will be quite competitive running native code, if not out-and-out faster, in comparison to other single-board computers. More to the point, being a full x86-64 CPU means it has a much larger library of software available than ARM CPUs.

        Technically you can make a single board computer with Ryzen given how it’s effectively an SoC. Of course you could do that with i5/7 also but I reckon you’d need a chipset. It’s just interesting how Ryzen packs everything in.

      AMD Raisin this is your cue.

    This looks ripe for a fun OPNsense build. The Realtek NICs are a little bit of a disappointment but I’ve had great success moving from pfSense to OPNsense as the latter has official driver support for Realtek NICs as of Feb 2017 release 17.1.2.

    There is even a SIM slot! Though it’s not clear what support there is for it as I can’t find anything on the Gigabyte page referring to it. The manual shows “U_SIM” on the motherboard layout page, but again, nothing speaking to what it can support for modems, etc.

      You’re one of the lucky ones then (or the drivers have improved markedly recently). The Realtek FreeBSD drivers are notoriously flaky, especially under load. The NICs also don’t support full-sized jumbo packets (the hardware is limited to 7422 bytes instead of 9000). That’s not a big deal for the average SoHo router but still, when you can pick up a used dual port intel for $50, it’s a hard sell unless you’re very space constrained.

        Good point about the jumbo frames. However, Realtek has fixed that in their later revisions of their NICs. See here: [url<][/url<] It is unclear which revision this board uses, but seeing as it's brand new and that thread was from 2015, it most likely supports full-sized jumbo frames.

    NUC boards are what? 4″x4″ and have dual DIMMs and dual M.2 slots. Just sayin.

      • Shobai

      The NUC’s got dual Ethernet, also? Quad serial ports? I guess they’ve got LVDS, I2C and GPIO hidden in there also?

      Horses for courses, cheif.

      I dunno… it does look a [i<]little[/i<] magical. That might be enough to overcome the headphone jack.
