ASRock Industrial SBC-250N 3.5″ SBC with Intel Elkhart Lake N6415, Dual 2.5GbE and Wide-Range DC Input

Sealed controllers and remote cabinets need a processor that stays within a small power budget, yet the application still benefits from four cores and several displays. The SBC-250N is the N6415 build in the ASRock Industrial SBC-250 series: a 3.5 inch SBC measuring 147 x 102 mm.

The N6415 is a quad-core Elkhart Lake SoC running at up to 3.0 GHz within 6.5 W. Two 260-pin DDR4-3200 SO-DIMM sockets run in dual channel for up to 32 GB. Intel Gen 11 Graphics drives three displays: HDMI 2.0b at up to 4096 x 2160 at 60 Hz, VGA at up to 1920 x 1200, and a shared connector for dual-channel 24-bit LVDS at up to 1920 x 1200 or eDP at up to 1920 x 1080, selected in BIOS. That suits a panel with a built-in LCD plus an external monitor.

I/O covers two 2.5GbE ports on Intel I225LM controllers, one USB 3.2 Gen2 and one USB 2.0 at the rear, and one USB 3.2 Gen1 plus five USB 2.0 on internal headers. COM1, COM2 and COM4 are RS-232 and COM3 is RS-232/422/485, with 4 GPI and 4 GPO for sensors and relays. An M.2 Key B (3042/3052) with PCIe x1 or USB 3.2 and a SIM socket takes a 4G or 5G module, an M.2 Key E 2230 takes wireless, and an M.2 Key M on PCIe x1 plus a SATA3 port hold storage. The SBC-250L is the dual-core N6210 build at the same 6.5 W, and the SBC-250D is the J6426 build at 10 W.

Power is 9 to 36 V DC on a 4-pin wafer connector, which covers 12 V and 24 V supplies, with AT and ATX power-on modes and a SATA power output for a drive. The SBC-250N operates from 0 to 70 °C and can be stored from -40 to 85 °C at 5 to 90% humidity. TPM 2.0 is onboard and a watchdog timer covers 0 to 255 seconds. The board, also called a 3.5 inch motherboard, is 22 mm tall.
