DFI ADS103 Intel 14th Gen Core Thin Mini-ITX SBCs with 15 to 36 V DC Input and PCIe Gen5 x16

Machine builders often have a 24 V DC rail in the cabinet already, and a board that runs from it directly saves a converter and the heat it adds. The DFI ADS103 series is a Thin Mini-ITX SBC with an LGA1700 socket and a 15 to 36 V DC input, in the standard 170 x 170 mm footprint. DFI gives a height of 33.3 mm above the board and 4 mm below, so it fits panel PCs and shallow enclosures as well as cabinet-mounted controllers.

The processor is a choice made per project. The socket takes 12th, 13th and 14th Gen Intel Core, Intel Core Series 2 (Bartlett Lake-S) in hybrid and P-core-only versions, Intel Processor 300, Pentium and Celeron, from two to 24 cores at up to 65 W TDP, so the TDP can follow the enclosure’s cooling budget, from 35 W T-series parts upwards. Two DDR4 3200 MHz SO-DIMMs hold up to 64 GB in dual channel, with ECC support on the R680E builds. Intel UHD Graphics drives two DP++ outputs at up to 4096 x 2304, internal LVDS or eDP, and a fourth display through DFI’s optional extension port for DP, HDMI or VGA.

Four builds cover the chipset and LAN options. ADS103-R680DB uses the R680E chipset with ECC support, Intel vPro and RAID, one 2.5GbE and one GbE port and six rear USB 3.2 Gen 2. ADS103-Q670DB has the same I/O on the Q670E with vPro and RAID but no ECC. ADS103-R680IB keeps the R680E features and adds a third Ethernet port, with four rear USB 3.2 Gen 2. ADS103-H610IB is the H610E build with three Ethernet ports, a smaller rear USB set and an M.2 M-key at PCIe Gen3 x1, for designs that need neither vPro nor RAID.

Every ADS103 board has two RS-232/422/485 ports and 8-bit DIO on internal headers, two SATA 3.0 ports and three M.2 slots: an M-key 2280 for NVMe (PCIe Gen4 x4 on the R680E and Q670E builds), a B-key with Nano SIM for a cellular module and an E-key 2230 for Wi-Fi. The PCIe x16 slot supplies up to 75 W to a capture, I/O or graphics card and runs at Gen5 on the R680E and Q670E builds.

The 15 to 36 V DC input arrives on a DC jack or a 4-pin connector. The boards operate from -5 to 65 °C and carry CE, FCC, UKCA and RoHS compliance, a discrete TPM 2.0, a watchdog programmable from 1 to 255 seconds and Realtek ALC888 audio. DFI lists Windows 10 IoT Enterprise, Windows 11 LTSC and Linux. For a 12 V supply, the ADS101 series is the same board with a 12 V DC input.
