DFI EC700-AL-E3930-2LAN Intel Atom x5-E3930 Low-Profile Embedded PC with 2x GbE and -40 to 70 °C

Data loggers and serial gateways at remote sites need little compute, but they do need low heat and a wide temperature rating. The EC700-AL-E3930-2LAN is the dual-core build of the DFI EC700-AL series for that work: a low-profile fanless embedded PC with an Intel Atom x5-E3930, four COM ports, two GbE ports and four USB 3.0 ports.

The Atom x5-E3930 runs two Apollo Lake cores, which suits logging, polling serial devices and forwarding data to a server. Memory is 2 GB of DDR3L onboard plus one 204-pin SO-DIMM, up to 8 GB in total, with 8 GB or 16 GB of eMMC depending on the build. Intel HD Graphics drives two displays, and the EC700-AL-E3930-2LAN runs Windows 10 IoT or Linux, as DFI states for Apollo Lake.

Networking is two Intel I210 GbE ports on RJ45, with four USB 3.0 Type-A ports, four RS-232/422/485 ports on DB9 and one DisplayPort output at up to 4096×2160 at 60 Hz and one VGA at up to 1920×1200. Storage is a 2.5-inch SATA bay and a full-size mSATA slot, plus the onboard eMMC. A full-size Mini PCIe slot with nano-SIM takes an optional 4G module, and an M.2 2230 E key slot takes optional Wi-Fi, with antenna holes on the front panel.

Power is 9 to 36 V DC on a DC jack. DFI rates the EC700-AL-E3930-2LAN from -40 °C to 70 °C and lists CE, FCC Class A, RoHS, CCC, UL and KC compliance, and it mounts on a wall, a VESA plate or a DIN rail with optional kits. We supply it configured and tested, with memory, storage, the OS image and any 4G or Wi-Fi modules fitted before it ships. The EC700-AL-E3930-4LAN has four GbE ports with the same processor, and the EC700-AL-E3940-2LAN steps up to four cores.
