⚠️ Important Notes

Memory Configuration for Optimal Performance: This board features two DDR4 SO-DIMM slots supporting dual-channel mode. For the best system and graphics performance, install two identical memory modules (same size, speed, and timings). Single-module operation will run in single-channel mode with reduced bandwidth.

Network Controller (Intel I226): Utilizes the latest Intel® I226 2.5GbE controllers. Verify driver availability and compatibility with your chosen operating system, especially for newer Linux kernels or specialized firewall distros.

High-Performance CPU & Power: The Elkhart Lake J6412 offers higher performance than previous generations. When used with dual-channel memory and under full network load, ensure a robust 12V DC power supply is used (recommended ≥ 90W).

Serial Port Configuration: The two COM ports default to RS232. The optional RS485 functionality applies to one of these ports only and must be specified during ordering if required.

M.2 SSD Support: The M.2 Key-M slot supports both 2242 and 2280 length SSDs and is compatible with SATA and PCIe NVMe protocols. For optimal performance in networking/server roles, an NVMe SSD is recommended.

Thermal Management: While fanless, the higher-performance CPU and quad 2.5GbE controllers can generate more heat under sustained load. Ensure the final system enclosure provides excellent passive cooling, particularly when operating near the upper temperature limit or in sealed boxes.
