Last month, I wrote about Turris Omnia an upcoming open source hardware router board with 6 Gigbit Ethernet ports and an SFP cage powered by Marvell ARMADA 385 processor. SolidRun has now unveiled ClearFog Pro router board with similar features, but opting instead for either Marvell ARMADA 380 or 388 processor.
The company will also soon launch or lower-end version called ClearFog Base with the less ports, but with the same system-on-module as ClearFog Pro:
- Processor – Marvell ARMADA 380 (88F6810) single core or 388 (88F6828) dual core ARMv7 processor (Cortex A9 class) @ up to 1.6 GHz with 1MB L2 cache, NEON and FPU
- System Memory – 256MB to 1GB 16-bit DDR3L (ARMADA 380) or 32-bit DDR3L (ARMADA 388)
- Storage
- Pro version – M.2 slot, 1x micro SD slot, 2x mSATA/mPCIE
- Base version – M.2 slot, 1x micro SD slot, 1x mSATA/mPCIE
- Connectivity
- Pro version – 6x switched Gigabit Ethernet ports, 1x dedicated Gigabit Ethernet port, 1x SFP cage
- Base version – 2x dedicated Gigabit Ethernet ports, 1x SFP cage (ARMADA 388 only)
- PoE expansion header
- USB – 1x USB 3.0 port
- Expansions
- 1x or 2x mini PCI Express slots (shared via mSATA above)
- GPIO header (mikroBUS standard)
- Audio/Telephony – Analog audio/TDM module support
- Debugging – micro USB port for serial console. Pro version only: JTAG header
- Misc – RTC with battery slot, LEDs, user push buttons
- Power Supply
- Pro version – 9V – 34V DC input; “advanced power control”; fan control
- Base version – 5V input; wide range ready
- Dimensions
- Pro version – 225 x 100 mm
- Base version – 160 x 100 mm (TBC)

The boards support Linux 3.x distributions such as OpenWRT and one build with the Yocto Project. The block diagram also shows two SIM card slots not listed in the specs, and which should be on the top right of the processor. The routers board are comprised of a baseboard and the company’s microSOM-a1 based on Marvell ARMADA 380, or microSOM-a2 with ARMADA 388 processor. The mikroBUS header allows you to use MikroElektronika Click add-on boards just like in HummingBoard-Gate board, and a module with audio and a SLIC would make the board suitable for VoIP applications too.
ClearFog Pro router board can be purchased right now for $170 without power supply, metallic enclosure or 8GB micro SD card, and if you want the full package you’ll need to spend $240, which includes $50 for the case itself. SolidRun did not say anything about price and availability for ClearFog Base board, except it’s coming soon. You can find further details, including documentation and schematics (PDF), on Solidrun’s ClearFog and ARMADA MicroSOM product pages.
