⚠️ Important Notes

Ultra-Compact Form Factor: This board uses a 120mm x 120mm PCB, much smaller than standard Mini-ITX. It is designed for specialized, space-constrained enclosures. Verify chassis compatibility before purchase.

Fanless Thermal Design: Designed for completely passive cooling. The end-user enclosure must provide adequate heat dissipation to maintain stable operation across the specified temperature range, especially under continuous load.

CPU & Memory Compatibility: Integrated Intel® Celeron J1900 (Bay Trail generation). Supports DDR3L SO-DIMM memory only (1.35V). Standard 1.5V DDR3 modules will not work and may cause damage.

Serial Port Configuration: Both COM ports use standard DB9 connectors and can be configured as either RS232 or RS485. This is a simpler and more standard implementation compared to some other models with special connectors.

Audio Jack: Features a single combo audio jack that functions as either a microphone input or a line output (typically selected in the operating system’s audio settings).

Power & Mode Setup: Use a stable DC 12V ±5% power supply. Correctly configure the AT/ATX mode jumper/BIOS setting for proper system power control.

Performance Expectation: The Intel Celeron J1900 is an entry-level, low-power platform ideal for basic computing, light I/O tasks, and simple display applications. It is not suited for computationally intensive workloads.
