Thermal & Power Engineering for Serial-Heavy Deployments
Safeguarding Port Stability in Harsh, High-Density Environments
Multiple serial ports demand more than just connectors—they require careful planning of thermal zones, power routing, and resilience features. Our industrial-grade COM boards support multiple power input configurations with built-in protections, ensuring that signal integrity and port performance remain stable under tough field conditions.
Zoned Cooling Around UART Bridges
Directed airflow over high-heat areas like transceivers and UART controllers ensures long-term reliability in tightly packed I/O clusters.
Flexible Power Input: 5V or 12V Ready
Each board supports per-port dual-voltage options, including inline polyfuse and ESD protection. Ideal for long-distance RS-485 or field sensor runs.
Smart Power Throttling
Firmware-defined current thresholds dynamically adjust port behavior to prevent thermal overshoot during surge or full-load events.
9–36V Wide-Range Input with Auto Reset
Designed for DC-powered enclosures and rail devices, all platforms support 9–36V input with transient filtering and watchdog-enabled reboot for brownout recovery.
Validated for Field Operation
All serial-focused boards pass thermal cycling (-20°C to +70°C), vibration hardening, and EMI immunity testing for deployment in mobile or factory-grade environments.
Consistency Across Voltage Inputs, Load Events & Serial Uptime
In field-grade and automation environments, a board’s ability to maintain I/O stability across variable power sources is non-negotiable. That’s why our serial-focused platforms are built around multi-input voltage design, lifecycle-stable components, and fixed power management mappings—so your deployment behaves predictably, no matter the input line or power event.
BOM-Locked Power Delivery Architecture
We lock all key power-regulation components—LDOs, polyfuses, power controllers—to ensure no variability across batches, eliminating behavior drift from sourcing changes.
Long-Term Voltage Controller Support
We align our DC-DC converter and switching ICs to controller roadmaps with 7+ year support to avoid drop-in replacements that impact serial signaling timing or stability.
Pre-Mapped Input Voltage Trees
Each board is shipped with validated power trees that match BIOS, kernel, and firmware expectations. This ensures consistent behavior for RS-232/485 performance across 5V, 9V, 12V, or 24V input scenarios—without requiring user-level tuning or redesign.
Real-World Reliability Enabled by Multi-Input Power Designs
From fluctuating voltage lines on factory floors to mobile deployments with backup batteries, power resilience is critical. Our multi-input-ready Mini-ITX platforms maintain system uptime and serial signal integrity—regardless of power source disruptions. Here’s how our designs meet real-world power challenges:
Dual Voltage Compatibility
Support both 12V and 24V DC input ranges for seamless integration across industrial cabinets, field terminals, and kiosk deployments—without custom wiring.
Mobile & Stationary Deployments
Whether you’re powering from PoE injectors, UPS-fed rails, or mobile battery systems, our flexible input design ensures safe, stable voltage delivery to core components and serial I/O.
Hot-Swap Ready Input Rail
Boards include reverse protection, inline fuses, and EMI filtering to tolerate power brownouts, surge events, and fast transitions between redundant supplies.
Designed for Isolation & Ground Loop Protection
Optional isolated power planes and common-mode choke layouts eliminate ground loop interference—ensuring clean power across distributed systems with long cable runs.
Flexibility for Real-World Deployment Conditions
In industrial and embedded environments, power availability isn’t always standardized. That’s why our serial port platforms are designed with multiple power input options—ensuring stable operation whether you’re deploying in kiosks, factory panels, or mobile systems.
