⚠️ Important Notes

Display Configuration (Critical Selection): This motherboard is offered in key display variants:

Standard: VGA + HDMI (most common for general use).
Optional: Dual HDMI (ideal for digital signage or dual digital monitors).

You must specify your required display configuration when ordering.

Serial Port Configuration: The board defaults to 2 x RS232 ports. If your application requires additional serial ports, an optional configuration supporting up to 4 x RS232 is available. This must be specified at the time of order.

USB Type-C Functionality: The included USB Type-C port’s specific capabilities (e.g., power delivery, Alternate Mode for video) should be verified based on the board’s design. It primarily functions as a high-speed USB data port.

TPM 2.0 Pinout & Module: Note the TPM header uses a 2×7 pin configuration. Ensure a compatible TPM 2.0 module is purchased separately for hardware security features. The module is not included.

Optional Audio Amplifier: The amplifier header is for an optional external component. If audio amplification is not required, this header can be left unpopulated.

M.2 SSD Boot Considerations: Booting from an NVMe SSD in the M.2 slot requires UEFI BIOS support. Ensure your operating system installation media and process are configured for UEFI mode.
