DFI GH171-R1505G Dual-Core AMD Ryzen Embedded R1505G Mini-ITX SBC with Dual GbE and Triple Display

A kiosk controller or thin client often needs a slot for one add-in card, a few serial devices and up to three screens, all on a modest power budget. The GH171-R1505G is the entry R1000 build in the GH171 series, a 15 W dual-core board on the 170 x 170 mm Mini-ITX footprint.

The AMD Ryzen Embedded R1505G has two cores and four threads at 2.4 GHz, boosting to 3.3 GHz, with three Radeon Vega compute units. On the R1000 builds the board drives three independent DP++ displays at up to 4096 x 2160 at 60 Hz, with hardware decode for H.265, H.264 and VP9. Two DDR4 3200 SO-DIMM slots take up to 32 GB.

Rear I/O has two GbE ports on Realtek RTL8111HN controllers, two USB 3.0 and two USB 2.0 Type-A ports, RS-232/422/485 and RS-232 DB-9 ports and audio. Internal connectors add four RS-232 ports, four USB 2.0 and a vertical USB 3.0 Type-A. The PCIe x16 Gen3 slot runs at x4 signal on this build, and storage is an M.2 M-key 2280 socket plus two SATA 3.0 ports.

Power is 12 V DC on a 4-pin connector or DC barrel jack, with 0 to 60 °C operation, an active cooler, TPM 2.0 and CE, FCC, UKCA and RoHS compliance. DFI lists Windows 10 and Linux support, and a watchdog timer programmable from 1 to 255 seconds resets the board if the kiosk software stops responding. The GH171-R1606G is the same board with the higher-clocked R1606G, while the GH171-V1202B adds a fourth display and x8 slot signal at the same 15 W.
