DFI IRN556-BN-N150 Intel N150 3.5″ SBC with 9 to 36 V DC Input and Dual GbE

Weighing terminals, retail counters and machine-side panels usually sit indoors, but they still connect more serial devices than a typical board supports. The IRN556-BN-N150 covers that with four COM ports and a quad-core processor at 6 W. It is the low-power Twin Lake option in the IRN556 series, an N150 SBC on the 3.5″ footprint, rated from -5 to 65 °C.

The Intel Processor N150 is a quad-core Twin Lake part running from 1.0 to 3.6 GHz within a 6 W TDP. Four cores keep a touch interface responsive while serial polling, logging and remote management run alongside, with little heat inside a compact enclosure. One DDR5 4800 MHz SO-DIMM slot takes up to 16 GB, and Intel UHD Graphics decodes HEVC, VP9, AV1 and AVC in hardware. DFI lists Windows 11, Windows 10 IoT Enterprise and Linux, with a discrete TPM 2.0 on board.

The dual-channel 24-bit LVDS connector drives a panel up to 1920 x 1200 at 60 Hz, and HDMI adds a customer or maintenance display. Two RS-232/422/485 and two RS-232 ports sit on internal headers with 8-bit DIO and two USB 2.0 ports. The rear carries two GbE ports on Intel I210IT controllers and four USB 3.2 Gen 2 Type-A ports, and M.2 sockets take an SSD, a cellular modem with nano SIM and Wi-Fi. A 5 W speaker output handles audible prompts.

The IRN556-BN-N150 runs fanless on 9 to 36 V DC through a 4-pin connector, with CE, FCC, UKCA and RoHS compliance. If the terminal needs more compute, the IRN556-BN-N355 offers eight cores at 15 W. For outdoor or unheated sites, the IRN556-TN-x7433RE keeps four cores with a -40 to 85 °C rating.
