Compute Module ALLNET Radxa CM3 Model A — 4 GB RAM, 32 GB eMMC

Compute Module ALLNET Radxa CM3 Model A — 4GB RAM, 32GB eMMC is a compact compute module designed for embedded systems and custom integrations. The module combines 4 gigabytes of RAM with 32 gigabytes of onboard eMMC storage, offering persistent local storage and sufficient memory for edge processing, media playback and IoT gateway functions. Its small form factor makes it suitable for integration into industrial controllers, prototypes and production devices where a reliable, always-available storage solution is required.

Advantages

The module provides a balanced combination of capacity and permanence: 4GB RAM supports multitasking and moderate workloads while 32GB eMMC delivers fast, reliable local storage that survives power cycles. The compact size simplifies integration into constrained enclosures and custom carrier boards. Designed for developers and integrators, it enables stable operation in continuous or unattended deployments and reduces the need for external storage devices.

Suitable for

• Embedded systems and industrial controllers
• Edge computing and data preprocessing
• Media players and digital signage
• IoT gateways and protocol bridges
• Prototyping and custom carrier board integrations

Key specifications

• Memory: 4 GB RAM
• Internal storage: 32 GB eMMC persistent flash
• Form factor: compact compute module for carrier board integration
• Use case orientation: embedded, industrial and edge applications
• Typical interfaces: carrier-board dependent I/O (GPIO, USB, network, display), subject to carrier design

How to use

Install the compute module onto a compatible carrier board or socket designed for the module form factor. Configure the operating system image and application software to use the onboard eMMC as the primary storage. Connect required peripherals (power, network, display, sensors) through the carrier board interfaces and verify device boot and system services. For development, use serial console and network access to deploy and debug applications before final integration.

Recommendations

For reliable long-term operation, secure the module on a proper carrier board with stable power supply and adequate cooling in confined enclosures. Use the onboard eMMC for system and application storage, and consider external storage only for large archival data. Verify carrier board compatibility and available I/O when planning integration.
