The Kongtai EIPC-J4125B is a fanless industrial mini PC built for embedded and desktop deployment. Its fully enclosed, full-aluminium black chassis measures only 136 x 127 x 40 mm and relies on a passive cooling design with no fans, so it runs silently, resists dust and requires almost no maintenance for continuous duty inside industrial control cabinets, kiosks and IoT gateways.

Powered by an Intel Celeron J4125 quad-core processor at 2.0 GHz, the EIPC-J4125B can be configured with 2 GB, 4 GB or 8 GB of memory and a 64 GB, 128 GB or 256 GB mSATA solid-state drive. Dual Gigabit Ethernet with network wake-up and PXE, VGA and HDMI dual-display outputs, two RS232 serial ports (optionally two RS485), four USB 3.0 and two USB 2.0 ports, and a Mini-PCIe slot for Wi-Fi or 4G modules cover a wide range of industrial interfaces. A standard 12V DC input with a 48W adapter, a 0 to 50 C working range and a hardware watchdog round out a compact and dependable box computer.

• Fanless full-aluminium chassis: A fully enclosed, full-aluminium black body with passive cooling runs silent, resists dust and vibration, and needs no fan maintenance.
• Intel Celeron platform: Ships with an Intel Celeron J4125 quad-core 2.0 GHz CPU, with the J1900 and N2840 versions available to match performance and cost targets.
• Dual Gigabit Ethernet: Two Gigabit network ports support network wake-up and PXE boot for redundant and managed network deployments.
• VGA and HDMI dual display: Simultaneous VGA and HDMI outputs drive two independent displays for control rooms, dashboards and information points.
• Two RS232 serial ports: Two RS232 ports, optionally configurable as two RS485, connect PLCs, meters, scanners and legacy industrial equipment.
• Six USB ports plus expansion: Four USB 3.0 and two USB 2.0 ports, plus a Mini-PCIe slot that accepts Wi-Fi or 4G modules without opening the case.
• Configurable memory and storage: Choose 2 GB, 4 GB or 8 GB of memory and a 64 GB, 128 GB or 256 GB mSATA SSD to suit each application.
• Compact metal body: A small 136 x 127 x 40 mm aluminium enclosure supports both embedded and desktop mounting in tight spaces.

The EIPC-J4125B suits industrial control, IoT gateways, kiosks and self-service terminals, digital signage, data acquisition and thin-client deployments. Its dual Gigabit ports, dual-display output, serial ports and Mini-PCIe expansion make it easy to connect PLCs, meters, cameras and wireless modules, while the fanless aluminium body keeps operation quiet and maintenance-free in dust-prone or space-limited installations.

Each unit ships with a standard 12V 4A power adapter and can be mounted for embedded or desktop use. The fanless aluminium enclosure protects the internal components during transport and operation, and Kongtai supports OEM and ODM configuration of processor, memory, storage, wireless modules and connectors to match each project.
