With processor soldered onboard, OXY5638B can significantly enhance the resistance of vibration and shock. Processor supports graphics (HD Graphics 6000 Series) and CPU performance and equips with rich legacy I/O features such as: 4 COM Ports; 6 USB Ports. What’s more, with 2 DisplayPort and a Dual Channel 24 Bit LVDS, and expansion slot 1 x PCIe_4, 4 x PCIe_1, 1 x PCIe x 4, 4 x PCIe x 1, 1 x mPCIe/mSATA, 1 x mPCIe, OXY5638B can fulfill diverse needs of modern day display & monitor control applications. OXY5638B can operate in harsh environment under temperature range from -40°C to 85 °C.


Key Features


(1)Rich I/O interface – Extensive Functionality

Rich I/O design endows OXY5638B with the ability to comprehend present day automation devices, display, and other applications that require extensive I/O features. With 4 COM, 6 USB, dual LAN ports, and dual Channel 24-bit LVDS, OXY5638B provides a wide array of choices to expand and connect to different devices.


(2)Extended Temperature Operation

7STARLAKE aims to provide excellent performance to all types of temperature zone. From component selection to layout design, we dedicate our knowledge to make sure that our boards can stand extreme temperature. OXY5638B can operate from -40°C to 85 °C, our strict manufacture procedure guarantees supreme performance in severe environment.


(3)Efficient thermal solution

A tailor-made heat spreader is what 7STARLAKE provide for engineers to reduce mechanical design period also ensures the highest efficacy for dissipation. For OXY5638B, the customized heat sink is placed on top of the CPU and chipset, acting as the medium that exchanges the heat to the surrounding atmosphere. The highly efficient aluminum heat sink has a thermal conductivity to absorb the heat generated by the pumping CPU.


Extended with PCIe/104+ connector for ultimate I/O & features expansion

The StackPC Specification defines new approach to stackable systems design and development. The specification includes all valuable heritages of PCIe/104 standards along with the new features of StackPC connector.

The main competitive distinction of the StackPC connector is the combination of most popular low speed interfaces such as USB, COM, CAN, SPI, LPC and high speed SATA, Gigabit Ethernet and PCI-Express x1, x4 within one OXY5368B
