DFI RPP173 Intel 13th Gen Core Mini-ITX SBCs with 9 to 36 V DC Input and Triple 2.5GbE

Plenty of machines and vehicles have no clean 12 V rail. A control cabinet runs from a 24 V DC supply, a mobile robot from a battery pack whose voltage sags under load, and a kiosk from whatever the enclosure builder fitted. The DFI RPP173 series accepts 9 to 36 V DC directly, so a 13th Gen Intel Core Mini-ITX board can sit on those supplies without an extra converter in the cabinet.

The compute matches the RPP171 series. Every RPP173 board takes two DDR5 5200 MHz SO-DIMMs in dual channel, up to 64 GB, and runs its processor at up to 28 W TDP. The Core i7 and i5 builds use Intel Iris Xe Graphics, and the i3 and U300E builds use Intel UHD Graphics. Two DP++ outputs drive up to 4096 x 2304 at 60 Hz, a rear USB-C port adds a third display through DisplayPort Alt Mode, and an M.2 A-key takes DFI’s optional M2A module for an eDP, LVDS, VGA, HDMI or DP panel.

Four builds cover the range. RPP173-IE-1365UE has the ten-core Core i7-1365UE at up to 4.9 GHz for multi-camera robots and inspection vehicles. RPP173-IE-1345UE uses the ten-core Core i5-1345UE at up to 4.6 GHz for HMIs and line controllers on 24 V. Both run from -20 to 70 °C. RPP173-IB-1315UE has the six-core Core i3-1315UE for indoor machine control, and RPP173-IB-U300E uses the five-core Intel Processor U300E for vending machines, kiosks and signage. These two run from -5 to 65 °C.

Each board has three 2.5GbE ports on Intel I226V and I226LM controllers, four rear USB 3.2 Gen 2 ports, four internal USB 2.0 headers, four COM ports (two RS-232/422/485 and two RS-232) and 8-bit DIO. An M.2 M-key runs NVMe at PCIe Gen4 x4, an M.2 B-key with a SIM slot takes a cellular module, an M.2 E-key (2230) takes Wi-Fi, and two SATA 3.0 ports and a PCIe x4 Gen4 slot add drives or an I/O card.

Power arrives on a barrel jack or a 4-pin connector, both rated 9 to 36 V DC. The boards ship with an active cooler as standard, with a fanless heatsink available on request for 15 W builds, 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 support for Windows 10 IoT Enterprise LTSB, Windows 11 and Linux. For projects on a fixed 12 V supply, the RPP171 series is the same board with a 12 V input.
