Frequently Asked Questions
Q: Why does fanless design matter for lockers?
A: Fans pull dust into electronics and are a common failure point in unattended cabinets. Passive cooling removes the moving part, extending maintenance-free service life.
Q: Can the board operate next to freezer compartments?
A: Yes. The -20°C to 70°C rating plus optional conformal coating against condensation makes the board suitable for freezer-side mounting in refrigerated lockers.
Q: How does the board handle power failures at remote sites?
A: Auto power-on restarts the board when electricity returns, the RTC keeps schedules accurate, and the watchdog recovers the system if software ever hangs.
Q: What testing is done before shipment?
A: Every batch passes a 48-hour high-temperature aging test, and the factory QC laboratory runs signal, interface and functional checks per ISO 9001 procedures.
Q: Is the board suitable for vibration environments?
A: The anti-vibration mounting and solid-state design tolerate vibration from nearby compressors, traffic and industrial machinery.
