Fujitsu D3543-S2 Intel Celeron J4105 BGA 1090 Mini-ITX Motherboard

The Fujitsu D3543-S2 Mini-ITX motherboard features the Intel Celeron J4105 processor for commercial hardware deployments. Designed for space-constrained environments such as edge gateways and retail point-of-sale systems, the board uses a pre-installed System-on-Chip based on the Gemini Lake architecture. This embedded design is intended for continuous operation in enclosed industrial chassis; the soldered processor eliminates socket compatibility issues and reduces long-term maintenance requirements.

Data storage options include SATA III connectivity and a dedicated M.2 interface for solid-state drives, compatible with 2242, 2260, and 2280 lengths. Networking is provided by two RJ45 ports, supporting dual 1GbE speeds for routing or system redundancy. Independent rear-panel video connectors allow for native dual-monitor setups, providing the necessary functionality for terminal builds without the need for additional expansion cards.
