Rugged, legacy PC/104 SBC taps dual-core Vortex86DX3 SoC

Nov 24, 2015 — by Eric Brown 989 views

Adlink’s rugged, Linux-friendly “CM1-86DX3” PC/104 SBC is built with DMP’s new dual-core Vortex86DX3 SoC, with 2GB RAM DDR3L and both Fast and GbE Ethernet.

The CM1-86DX3 is the first board we’ve seen to run DMP’s latest Vortex-branded x86 architecture SoC, the Vortex86DX3. Announced in April, the dual-core, 1GHz SoC builds upon the design of the earlier, single-core, 800MHz to 1GHz Vortex86DX2, found on Adlink’s circa-2013 PC/104 board, the CM1-86DX2. The DX3 offers double the L1 and L2 cache of the DX2, and adds support for DDR3 memory.

The Adlink CM1-86DX3 provides the 2GB maximum of DDR3L RAM, soldered to the board, and features both a Gigabit Ethernet port and a 10/100 Ethernet PHY. Otherwise, this is a more limited, more legacy-oriented board than the fairly similar CM1-86DX2. As is the case with most PC/104 form-factor SBCs, there are no real-world coastline I/O ports, only pin interfaces.

The CM1-86DX3 offers full, legacy ISA bus support per PC/104 2.6 specifications, and supports SATA and CFast storage. The SBC is equipped with and VGA and 18/24-bit, single-channel LVDS video interfaces, along with dual USB 2.0 ports, two RS-232/422/485 serial ports, and two RS232 serial ports. There’s also a PS/2 port, and eight GPIO lanes. The only expansion opportunity is through the PC/104 interface.

The board can withstand 50G shock and 12G vibration per MIL-STD-202F, and supports a 0 to 60°C temperature range. It also features Adlink’s SEMA (Smart Embedded Management Agent) cloud hardware monitoring functionality. Applications for the CM1-86DX3 include industrial automation, transportation, energy, and military applications “requiring industrial-grade stability,” says Adlink.

    Fascinating – and a good idea, like Stackable PC/104 will always be a good idea; even 20 years later
