DFI RPS330 Intel Bartlett Lake and 14th Gen Core Micro-ATX Industrial Motherboards with Six COM Ports and PCIe Gen5 x16

Machine controllers and test stands built a decade ago often rely on serial instruments and PCI cards that still do their job. Moving them to a current processor usually means finding a board that keeps both. The DFI RPS330 series does that on the 244 x 244 mm Micro-ATX footprint, with six COM ports and two PCI slots on an LGA1700 socket, so these Micro-ATX industrial motherboards take current Intel processors without dropping the older interfaces.

The socket supports 12th, 13th and 14th Gen Intel Core, Intel Core Series 2 (Bartlett Lake-S), Intel Processor 300, Pentium and Celeron parts, from two to 24 cores at up to 125 W TDP. Memory is DDR5 4400 MHz on DIMM slots. Intel UHD Graphics drives three independent displays through VGA, a DP++ port up to 4096 x 2304 at 60 Hz and HDMI 2.0a, and DFI lists Windows 10 IoT Enterprise, Windows 11 LTSC and Linux support.

The RPS330-Q670E uses the Intel Q670E chipset with four DIMM slots for up to 192 GB, a PCIe Gen5 x16 slot, two 2.5GbE ports, Intel AMT, an M.2 E-key socket for Wi-Fi and RAID 0, 1, 5 and 10. The RPS330-H610E uses the H610E chipset with two DIMM slots for up to 96 GB, a PCIe x16 slot, one 2.5GbE and one GbE port and a smaller USB set, for cost-sensitive builds that do not need remote management or RAID.

Both boards keep a PCIe x4 Gen3 slot and the two PCI slots, two M.2 M-key sockets for NVMe SSDs (one PCIe x4, one PCIe x2 or SATA) and four SATA 3.0 ports. The six serial ports are one RS-232/422/485 on a rear DB9, another on an internal header and four RS-232 headers, with 4-in/8-out digital I/O. The Q670E build has four USB 3.2 Gen 2 Type-A ports at the rear, the H610E build two USB 3.2 Gen 2 and two USB 3.2 Gen 1, and both add rear and internal USB 2.0.

Power comes from a standard ATX supply over 24-pin and 8-pin connectors, with a -5 to 65 °C operating range for indoor cabinets, benches and control rooms. A TPM 2.0 and a watchdog timer programmable from 1 to 255 seconds support secure, unattended operation, and the series carries CE, FCC, UKCA and RoHS compliance.
