⚠️ Important Notes

CPU Generation & Compatibility: Supports 6th Gen (Skylake) and 7th Gen (Kaby Lake) U-series processors. Verify CPU compatibility (socket and TDP) before purchase and installation. Note that 8th Gen processors (e.g., i5-8250U) are part of the Kaby Lake Refresh family and require explicit BIOS/board compatibility confirmation.

M.2 Storage Configuration: The M.2 Key-M slot supports both SATA and PCIe (NVMe) SSDs in the 2280 form factor. The slot auto-switches, but ensure your SSD matches the supported interface. Booting from NVMe may require UEFI BIOS and OS support.

Serial Port Configuration (Critical): The board defaults to 2 x RS485. If your application requires RS232 or up to 4 RS232 ports, this is an optional configuration that must be specified when ordering. Do not assume RS232 is present by default.

TPM 2.0 Security: The TPM 2.0 functionality requires a separate TPM module to be installed on the provided header. This is not included with the base board but is essential for enabling hardware-based security features like BitLocker drive encryption.

Display Output Option: The secondary display port is either VGA or DisplayPort as a configurable variant. Confirm which interface your specific board includes for your monitor setup.

Power & Thermal: With support for higher-performance CPUs and NVMe storage, ensure the 12V DC power supply is robust (recommended ≥ 90W). The fanless design must be paired with adequate system-level passive cooling, especially under high load.
