We’ve seen a fair amount of AMD Ryzen Embedded boards over the last few months including 3.5″ Ryzen Embedded SBC‘s such as Kontron SBC-VR1000 and IBASE Technology IB918, as well as larger boards such as SAPPHIRE FS-FP5R 5×5 motherboard.

The most compact Ryzen Embedded board we covered so far must have been the upcoming Sapphire NP-FP5 based on Ryzen R1305G processor with a 4″x4″ (10.16 x 10.16 cm) form factor. But DFI GHF51 1.8″ SBC takes the crown of the smallest Ryzen Embedded SBC, with the business card / Raspberry Pi sized board measuring just 84 x 55 mm, and featuring an AMD Ryzen Embedded R1000-series processor combined with up to 8GB RAM.

DFI GHF51 specifications:

SoC – AMD Ryzen Embedded R1000 Series with Radeon Vega 3 GPU; 12W CPU

System Memory – 2GB/4GB/8GB single-channel DDR4 3200MHz

Storage 1x 16GB/32GB/64GB eMMC flash 64Mbit SPI Flash for BIOS (supports UEFI boot only)

Video Output – 2x micro HDMI 1.4 ports up to 4096×2160 @ 24Hz each

Connectivity Gigabit Ethernet via Intel I211AT or I210IT controller

USB – 1x USB 3.1 Gen 2, Type C port

Expansion 1x Full-size Mini PCIe socket with PCIe Gen2/USB 2.0, optional USB 3.1 Gen2 8-bit DIO header SMBus header

Security – TPM 2.0

Misc – Watchdog Timer, CR2032 Coin Cell for RTC

Power Supply – 12V +/-5% DC via 2-pin terminal block

Dimensions – 84 x 55mm (1.8″ SBC form factor)

Temperature Range – Operating: 0 to 60°C (Option: -20 to 70°C); storage: -40 to 85°C

Humidity – Operating: 5 to 90% RH; storage: 5 to 90% RH

The board supports operating systems booting via UEFI such as Windows 10 IoT Enterprise 64-bit and Linux distributions.

There’s no pricing nor availability information on the product page, but you’ll find a user manual and quick reference for the board that shows the board is cooled with a heat spreader included by default. Having said that, LinuxGizmos reports the SBC should launch in Q3 2020, and the company has another similar new board ( ALF51) based on Atom E3900 processor that sells for $282 with 2GB RAM, 32GB eMMC flash. DFI GHF51 should be in this range, possibly even higher.
