Hummlink HM-G14 Fanless In-Vehicle Industrial Mini PC | Intel N100 / J6412, Dual 2.5GbE LAN, 6x COM, 9-36V DC Phoenix for Fleet & AGV

Hummlink HM-G14 is a rugged, fanless in-vehicle industrial computer engineered specifically for transit bus management systems, fleet telematics, autonomous mobile robots (AMR/AGV), and industrial edge automation. Powered by energy-efficient Intel Celeron J4125 (10W), Celeron J6412 (10W), or 12th Gen Intel N100 (6W) processors, the HM-G14 features wide 9V–36V DC input via an industrial 4-pin Phoenix terminal, dual Intel i225-V 2.5GbE Ethernet ports, 6 DB9 COM serial ports (with 2 supporting RS422/RS485), 10-way isolated GPIO, and M.2 cellular expansion supporting up to 5 external antennas for high-reliability 4G/5G connectivity.

Target Applications

• Transit Bus & Fleet Telematics: Direct compatibility with 12V and 24V vehicle battery systems, ignition-aware power control, onboard GPS/4G/5G cellular tracking, and multi-camera passenger counting.
• Autonomous Mobile Robots (AMR) & AGVs: Ultra-low power consumption (6W–10W TDP), compact low-profile chassis (50 mm height), and vibration-resistant Phoenix terminals make it the ideal onboard compute brain for robotics.
• Industrial Edge Telemetry & SCADA: High-density serial integration (6x COM, 2x RS485/RS422) and 10-way GPIO enable direct communication with PLCs, RTUs, barcode scanners, and energy meters.
• Intelligent Transportation Systems (ITS) & Toll Gates: Dual 2.5Gbps high-speed networking connects license plate recognition (LPR) cameras and barrier gate controllers without packet loss.

Key Hardware Highlights

• Ultra-Low Power Processors: Choose between Intel Celeron J4125 (4C/4T, 10W), Celeron J6412 (4C/4T, 10W), or 12th Gen Intel N100 (4C/4T, 6W) for silent, energy-saving 24/7 continuous operation.
• Dual Intel i225-V 2.5GbE Ethernet: High-speed 10/100/1000/2500 Mbps RJ45 ports for high-bandwidth IP cameras, lidar sensors, and local control subnets (expandable up to 4 LAN ports).
• 6 DB9 COM Serial Ports: 2 × RS232/RS422/RS485 multi-mode switchable COM ports plus 4 × RS232 COM ports for legacy sensors and machine interfaces.
• 10-Way GPIO & Remote Power Switch: Industrial terminal header offering 10-channel digital I/O for sensor triggers, relay activations, and external cabinet power buttons.
• Wide DC 9V–36V Power Input: Heavy-duty 4-pin Phoenix terminal block prevents accidental disconnects in vibrating vehicle cabins and plant floors (100–240V AC power adapter included).
• Flexible Memory & Storage: Supports DDR4 (J4125/J6412) or DDR5 (N100) up to 32GB RAM; triple storage options including M.2 NVMe, M.2 SATA, and 2.5\" SATA SSD/HDD.
• Advanced Wireless & Cellular (5 Antennas): M.2 2230 slot for WiFi/Bluetooth + M.2 3042/3052 slot for 4G LTE or 5G Sub-6 modules with onboard SIM slot and 5 SMA antenna cutouts.
• Rugged Fanless Enclosure: Heavy-duty black aluminum alloy heatsink chassis rated for -20°C to +60°C operating conditions, resistant to shock, vibration, and dust.
• Embedded Reliability Features: Hardware Watchdog timer (0–255 sec), Auto Power On (AWAL), RTC Wake-up, Wake-on-LAN, and PXE Boot.

Frequently Asked Questions (FAQ)

Q: How does the HM-G14 handle fluctuating vehicle power and battery cranking dips?
A: The HM-G14 features an onboard wide-range DC-DC regulator supporting 9V to 36V DC. It absorbs common voltage fluctuations, transients, and cold-cranking voltage sags found in 12V automotive and 24V bus/truck electrical systems. The 4-pin Phoenix terminal connector ensures a secure, vibration-proof physical connection.

Q: Can the unit accommodate both WiFi/BT and a 4G or 5G cellular modem at the same time?
A: Yes. The motherboard provides two dedicated M.2 slots: one M.2 Key-E (2230) for high-speed WiFi/Bluetooth cards, and one M.2 Key-B (3042/3052) paired with an onboard SIM card slot for full-size 4G LTE or 5G cellular communication. Up to 5 external antenna pass-throughs are provided on the chassis.

Q: Can the HM-G14 be mounted onto an industrial DIN rail inside a control cabinet?
A: Yes. In addition to standard wall-mounting brackets, an optional industrial DIN-rail clip kit is available. Its compact 50 mm height allows it to fit neatly alongside PLCs, circuit breakers, and power supplies in shallow DIN-rail enclosures.

Q: How are RS422 and RS485 communication modes configured on the COM ports?
A: COM1 and COM2 are multi-mode serial interfaces supporting RS232, RS422, or RS485 via internal jumper pin selection or BIOS settings. Automatic data flow control (ADDC) is integrated for seamless half-duplex RS485 communication with Modbus RTU devices.

Q: Does Hummlink support custom branding, custom I/O wiring harnesses, or volume B2B quotes?
A: Yes. Hummlink provides comprehensive OEM/ODM customization, including custom chassis laser etching, custom BIOS splash screens, custom OS images, and specialized Phoenix wire pigtails. Bulk discounts are available for project deployments starting from 5 units.
