Combining cutting-edge DDR5 memory support, ultra-fast M.2 NVMe storage, Intel Iris Xe graphics, dual Gigabit LAN, 2 COM ports, and 8 USB interfaces within a rugged aluminum alloy chassis, the HM-G12 is engineered for 24/7 continuous operation in interactive kiosks, point-of-sale (POS) systems, digital signage, edge computing, and industrial automation.

Target Applications

• Smart Kiosks & Self-Service Terminals: Compact low-profile footprint (57.2 mm height) and 8 USB ports allow direct integration of thermal receipt printers, QR/barcode scanners, cash acceptors, and touch displays.
• Digital Signage & Ultra-HD Multimedia: Powered by Intel Iris Xe Graphics with native HDMI 2.0 (4K @ 60Hz) and VGA dual independent displays, ensuring smooth 4K hardware-accelerated video decoding.
• Industrial Edge Computing & Machine Control: 12th Gen hybrid multi-core processing with fast DDR5 memory bandwidth provides ample computing power for local data aggregation, vision preprocessing, and telemetry.
• Retail POS & Hospitality Terminals: Silent fanless passive heat dissipation eliminates dust buildup and fan noise in retail and restaurant checkout counters.

Key Hardware Highlights

Frequently Asked Questions (FAQ)

Q: What DDR5 memory speeds and capacities does the HM-G12 support?
A: The HM-G12 features a standard 262-pin DDR5 SO-DIMM slot supporting DDR5-4800MHz non-ECC memory modules in 8GB, 16GB, 32GB, and up to 64GB capacities. DDR5 delivers nearly double the bandwidth of DDR4, significantly boosting AI inference and multi-stream 4K decoding performance.

Q: Can the HM-G12 drive two displays simultaneously at different resolutions?
A: Yes. The HDMI 2.0 port supports resolutions up to 4K (3840×2160 @ 60Hz), while the VGA port supports up to 1920×1200 @ 60Hz. Both video outputs can operate concurrently in either extended desktop mode or cloned (mirror) display mode.

Q: How does the passive cooling perform inside enclosed kiosk or terminal housings?
A: The HM-G12 utilizes a solid extruded aluminum alloy chassis with integrated thermal conduction blocks directly contacting the 15W TDP processor. Operating temperature is validated from -20°C to +60°C. For tightly sealed kiosks, we recommend maintaining minimal convection spacing around the top finned heatsink.

Q: Does the system automatically restart after a power interruption?
A: Yes. Hardware Auto Power On (Restore on AC Power Loss / AWAL) is built into the AMI BIOS. In the event of an unplanned power loss, the computer boots immediately when power is restored, eliminating the need for manual on-site button pressing.

Q: Can we request custom BIOS splash screens, OS pre-installations, or barebone shipments?
A: Yes. Hummlink provides custom BIOS branding (logo customization), volume barebone options (no RAM / no SSD), specific industrial-grade memory/storage installation, and OEM laser marking on the chassis. Contact our engineering team for project quotes.
