Frequently Asked Questions

The key differences are: the SKLU uses U-series processors (i7-6600U, i5-6300U, i3-6100U) focused on power efficiency, while the SKLH uses higher-performance quad-core E-series processors; the SKLU provides more COM ports (6 vs. 2 on SKLH); the SKLU offers fewer SATA ports (1 vs. 2 on SKLH); the SKLU has a wider power input range (12-24V vs. 12V only); and the SKLU includes a SIM card slot. The SKLU is better suited for applications requiring extensive connectivity and lower power consumption.

3.5-inch SBCs (Single Board Computers) are compact embedded computers measuring approximately 146mm x 101mm (5.75" x 4"). Their versatile form factor makes them ideal for applications requiring a balance of performance, I/O options, and size constraints, including industrial automation, IoT gateways, edge computing, digital signage, medical devices, transportation systems, robotics, and industrial control systems.

3.5-inch SBCs offer several advantages: a balanced form factor between size and functionality; rich I/O options without requiring expansion cards; better thermal management than smaller boards; good performance-to-size ratio; flexibility with both soldered and socketed CPU options; simplified integration into mid-sized enclosures; good scalability for industrial applications; and long lifecycle support typical of industrial-grade components.

Different Intel processor generations provide varied capabilities: newer generations offer enhanced multi-core performance, AI acceleration, and support for faster memory; mid-range options balance performance and power efficiency for IoT and edge applications; while entry-level processors optimize for low power consumption and extended temperature ranges. The choice involves balancing processing requirements, power constraints, thermal considerations, and specific features needed for the target application.

Key factors include: processing requirements for your workload; memory and storage configurations; specific I/O interface requirements; networking needs; temperature operating range; power constraints; expansion capabilities; long-term availability guarantees; operating system support; ruggedness including shock and vibration resistance; certifications required for your industry; and total cost of ownership including maintenance and support.

Effective cooling strategies include: ensuring adequate airflow (at least 0.5 m/s); using conduction cooling with thermal pads connecting to the enclosure; implementing passive cooling solutions like aluminum enclosures with external fins; maintaining adequate clearance around heat-generating components; arranging components to create a natural convection path; implementing thermal monitoring; and for extreme environments, using specialized cooling techniques like heat pipes or forced air cooling.

Important power considerations include: providing stable DC input within the specified voltage range with proper regulation; understanding AT versus ATX power modes; implementing proper power sequencing; adding surge protection for industrial environments; implementing power filtering to eliminate electrical noise; calculating total power budget including peripherals; planning for power management; using high-quality power connectors; and potentially implementing backup power solutions for critical applications.

Expansion options include: utilizing M.2 or Mini PCIe slots for adding connectivity or storage; leveraging multiple display outputs; using USB expansion for additional peripherals; implementing I2C, SPI, or GPIO-based sensor networks; utilizing multiple Ethernet ports for network segregation; developing custom carrier boards; implementing software-based capabilities through virtualization; and considering network-based resources for functions that cannot be implemented locally.

Common bottlenecks include: thermal limitations (addressed through proper cooling); memory bandwidth constraints (mitigated by using faster memory); storage I/O (improved by using NVMe over PCIe); network congestion (overcome by using optimized networking); USB bus saturation (resolved by distributing devices across controllers); processor limitations in multi-threaded workloads (addressed through workload optimization); and display performance with multiple screens (managed by understanding bandwidth limitations).

Recommended mounting practices include: using the four corner mounting holes with appropriate standoffs; maintaining minimum clearances; ensuring proper thermal contact if using conduction cooling; considering orientation effects on cooling; using vibration-resistant fasteners for applications with vibration; implementing strain relief for cables; avoiding mounting near EMI sources; ensuring accessibility for maintenance; and verifying that the enclosure's thermal design is compatible with the board's cooling requirements.

Best handling practices include: using proper ESD protection; holding the board by its edges; avoiding flexing the PCB; ensuring power is off when connecting components; using appropriate torque for mounting screws; applying thermal compounds correctly; connecting cables with proper orientation; ensuring expansion cards and memory modules are properly seated; avoiding exposure to moisture or contaminants; and following proper packaging procedures for transportation.

Best practices include: using high-quality, shielded cables; implementing strain relief; connecting power supplies before signal cables; using locking connectors where available; avoiding exceeding maximum cable lengths; balancing loads across multiple ports; verifying peripheral power requirements; properly configuring serial port parameters before connecting devices; testing peripherals individually; and labeling all connections for maintenance.

Proper OS setup involves: obtaining manufacturer-recommended OS images; configuring BIOS/UEFI settings appropriately; optimizing partition layouts; installing essential drivers; disabling unnecessary services; configuring appropriate power management settings; implementing a backup strategy; establishing a procedure for OS updates that includes proper testing; and documenting the entire configuration process.

Troubleshooting steps include: verifying power supply voltage and current capability; checking for reverse polarity connection; examining power cables; inspecting for physical damage; testing with a known-good power supply; verifying the correct power mode configuration; checking power switches or jumpers; measuring voltage at test points; inspecting for short circuits; and checking status LEDs for error codes.

Diagnostic steps include: checking cable connections; verifying monitor power and input selection; confirming resolution compatibility; trying alternative display interfaces; updating display drivers; resetting BIOS display settings; testing with a known-working display; checking BIOS settings for primary display selection; verifying multi-display configuration; inspecting system logs; and potentially reinstalling graphics drivers or updating the BIOS.

Common causes include: physical connection problems; driver issues; incorrect IP configuration; firewall or security software blocking communication; conflicting IP addresses; switch or router configuration issues; hardware failure; incorrect gateway or DNS settings; disabled protocols; packet filtering rules; VLAN mismatches; and network congestion. Troubleshooting should include link status verification, ping tests, checking logs, and testing with alternative equipment.

Troubleshooting steps include: verifying proper insertion and securing; checking compatibility with the slot type; confirming BIOS recognition; verifying controller settings; updating BIOS; checking for required drivers; testing in another system if possible; verifying power management settings; checking thermal conditions; and for storage devices, running diagnostic tools to verify device health.
