Key specifications

• System memory: 4 GB RAM
• Onboard storage: 32 GB eMMC persistent flash
• Compact compute module form factor for carrier-board integration
• Low-profile design suitable for space-constrained installations
• Designed for continuous, embedded operation

How to use

Install the module into a compatible carrier board or custom-designed PCB that exposes required interfaces such as power, I/O, and peripherals. Provide appropriate power and cooling according to the carrier board design documentation. Flash or configure the operating system and application software to use the onboard eMMC as primary storage or as additional persistent storage. Connect network, display, sensors, or storage peripherals via the carrier board interfaces as required for the specific application.

Recommendations

Ensure that the carrier board and enclosure provide adequate power regulation and thermal management. Use the onboard eMMC for OS and critical data, and consider external storage for high-capacity or high-write workloads. Keep firmware and drivers up to date to maintain stability and security in embedded deployments.
