DFI IRN556-TN-x7433RE Quad-Core Intel Atom x7433RE 3.5″ Industrial Motherboard with 9 to 36 V DC Input and -40 to 85 °C

An operator station on outdoor or mobile equipment typically combines a display with a handful of serial devices: a scanner, a printer, a scale or a PLC. The IRN556-TN-x7433RE handles all of them with four cores at 9 W. It is the quad-core Amston Lake option in the IRN556 series, a 3.5″ industrial motherboard with an LVDS panel output and four COM ports, rated from -40 to 85 °C.

The Intel Atom x7433RE is a quad-core Amston Lake processor running from 1.5 to 3.4 GHz within a 9 W TDP. Four cores keep a Windows or Linux HMI responsive while serial polling and logging run in the background. Memory is one DDR5 4800 MHz SO-DIMM slot for up to 16 GB, and Intel UHD Graphics decodes HEVC, VP9, AV1 and AVC in hardware. A discrete TPM 2.0 and a programmable watchdog are on board.

The dual-channel 24-bit LVDS connector drives a panel up to 1920 x 1200 at 60 Hz, and HDMI adds a second screen. Two RS-232/422/485 and two RS-232 ports sit on internal headers with 8-bit DIO and two USB 2.0 ports. On the rear are two GbE ports on Intel I210IT controllers and four USB 3.2 Gen 2 Type-A ports. M.2 sockets take an SSD, a cellular modem with nano SIM and Wi-Fi, and Realtek audio includes a 5 W speaker output for operator alerts.

The IRN556-TN-x7433RE runs fanless on 9 to 36 V DC through a 4-pin connector, with CE, FCC, UKCA and RoHS compliance. For the lowest heat at the same rating, the IRN556-TN-x7211RE runs two cores at 6 W. Where the workload needs eight cores, the IRN556-TN-x7835RE runs at 12 W.
