Physical Installation
Mounting
Ensure all cables are disconnected.
The board can be integrated into industrial enclosures compatible with the 3.5" form factor.
Connecting Peripherals and Power
- Power: Connect a 9–24V power supply to the Molex 2P connector (0768290102).
- Display: Connect a monitor via HDMI port.
- Input: Connect USB keyboard and mouse.
- Network: Connect via Ethernet or install wireless M.2/mPCle modules.
First Boot & OS Setup
On startup:
- The system initializes based on the boot switch configuration.
- Booting is supported from eMMC, SSD (via M.2), or MicroSD.
- If no OS is pre-installed, load the OS image of your choice onto a bootable USB drive.
- Supports standard operating systems for SMARC modules, such as Embedded Linux or Windows IoT.
Power Management & Thermal Considerations
- Supported voltage: 9–24VDC with built-in protection.
- Cooling depends on the installed SMARC module: provide passive or active cooling based on thermal load.
- For harsh environments, use industrial-grade SMARC modules for extended temperature ranges beyond 0°C ~ +70°C.
