DFI RPS100 Intel 12th to 14th Gen Core Mini-ITX Motherboards with Dual 2.5GbE and PCIe Gen5 x16

A Mini-ITX board that feeds a full-length GPU or frame grabber from its own x16 slot, runs from a standard ATX supply and still fits a 170 x 170 mm footprint covers a lot of OEM designs: vision cells, test rigs, medical carts and small edge servers. The DFI RPS100 series is built for that brief, with a socketed LGA1700 processor chosen to suit the workload rather than fixed on the board.

Each RPS100 board accepts Intel Core Series 2 (Bartlett Lake-S) processors, 14th, 13th and 12th Gen Intel Core, Intel Processor 300 and Pentium and Celeron parts, including the 12-core Core 9 273PE. Supported processors run from two to 24 cores at up to 65 W TDP, and the 35 W and 45 W T-series parts suit enclosures with less cooling. Two DDR5 4800 MHz SO-DIMMs take up to 64 GB in dual channel. Intel UHD Graphics drives HDMI, DP++ at up to 3840 x 2160 and 60 Hz, and VGA at the rear, and DFI’s optional M2A display module on the M.2 A-key adds an LVDS or eDP panel as a fourth display.

Three chipset builds make up the range. RPS100-R680EDB uses the Intel R680E, supports ECC memory with Core i7 and i5 processors and has two USB 3.2 Gen 2 and four USB 3.2 Gen 1 ports at the rear. RPS100-Q670EDB uses the Q670E with six rear USB 3.2 Gen 1 ports. Both pair Intel I226LM and I226V controllers for their two 2.5GbE ports. RPS100-H610EDB uses the H610E with two I226V ports and a rear mix of four USB 3.2 Gen 1 and two USB 2.0 ports.

Every board carries two RS-232/422/485 ports, 8-bit DIO, two internal USB 2.0 and two SATA 3.0 ports. The M.2 M-key (2280) runs NVMe at PCIe Gen3 x4 or SATA, the M.2 E-key (2230) takes a Wi-Fi and Bluetooth module with Intel CNVi support, and the A-key (3060) carries the display module or a PCIe Gen3 x1 device. On the R680E and Q670E builds, the PCIe x16 slot runs at Gen5 as one x16 or two x8 links for a GPU, a capture card or a pair of network cards.

Power comes from an ATX supply on 24-pin and 4-pin connectors, which suits enclosures already designed around a standard PSU. The boards operate from -5 to 65 °C and carry CE, FCC, UKCA and RoHS compliance, a discrete TPM, a watchdog programmable from 1 to 255 seconds and Realtek ALC888S audio. DFI lists Windows 10 IoT Enterprise, Windows 11 LTSC and Linux, and offers 65 W and 35 W thermal solutions to match the chosen processor.
