Mini-ITX embedded motherboard with Intel Celeron J6412, dual-channel DDR4, five SATA 6Gb/s ports, dual GbE LAN and extensive serial I/O for industrial automation
This Mini-ITX motherboard integrates an Intel Celeron J6412 processor for fanless edge deployments. It targets system builders who need a compact platform for industrial automation, AI robotics or smart retail installations. Dual-channel DDR4 SO-DIMM slots provide memory flexibility. The board is not suited for workloads that demand discrete GPU acceleration or high-core-count server processors.
Under continuous load the J6412 maintains its base frequency without thermal throttling in passively cooled chassis designs. Five SATA 6Gb/s ports, one supporting SATA DOM, deliver steady storage throughput for logging and inference datasets. A single PCIe x1 Gen 3 slot allows addition of capture or I/O cards without bandwidth saturation during long runs. The platform is not for tasks that require sustained multi-threaded performance beyond four efficient cores.
The board operates from a 12 V to 24 V DC jack, drawing minimal power for silent, fanless operation in sealed enclosures. Heat spreads across the aluminium backplate, keeping surface temperatures low during 24/7 duty cycles. Two GbE LAN ports and eight USB ports maintain connectivity without adding active cooling. Builders who need redundant power inputs or PoE sourcing must look elsewhere.

The board accepts a wide 12V to 24V DC supply through the DC jack; the J6412 is a 10 W TDP processor, so sustained load stays low and passive cooling is practical in most enclosures.
You need two DDR4 SO-DIMMs for the dual-channel slots and up to five SATA 6Gb/s drives, one of which can be a SATA DOM, to populate the onboard storage ports.
Yes, two rear ports handle RS-232/422/485 with selectable 5V or 12V on pin 9, and four internal headers provide additional RS-232 connections for legacy equipment.
