Compute Module ALLNET Radxa CM3 Model A 4 GB RAM senza eMMC e Wi-Fi

Compute Module ALLNET Radxa CM3 Model A 4GB RAM without eMMC and WiFi is a compact development module designed for embedded systems, industrial controllers and custom prototyping. The module provides 4GB of system memory and exposes interfaces for external storage and peripheral connectivity. Omitting onboard eMMC and WiFi enables greater flexibility for projects that require specific storage types or separate wireless solutions.

Advantages

This compute module delivers a small physical footprint and modular design suitable for space-constrained applications. The 4GB RAM supports multitasking and memory-intensive embedded workloads while the absence of onboard eMMC reduces cost and allows designers to choose preferred external storage media. Lack of built-in WiFi simplifies regulatory requirements and enables integration with dedicated wireless modules or wired networking for industrial environments.

Suitable for

• Embedded systems and single-board computer carriers that require modular memory
• Industrial automation and control panels where custom storage and connectivity are needed
• Prototyping and development of IoT gateways with external storage or separate wireless modules
• Education and research projects that require a stable compute module without integrated wireless

Key specifications

• System memory: 4 GB RAM
• Onboard storage: none (no eMMC included)
• Wireless connectivity: none (no integrated WiFi)
• Form factor: compact compute module for carrier boards
• Interfaces: exposed peripheral and storage interfaces for external devices

How to use

Install the compute module into a compatible carrier or development board that provides required power, I/O and optional storage interfaces. Attach external storage such as an SD card or an external eMMC/flash solution via the carrier board where needed. Integrate wireless connectivity using a separate WiFi or cellular module on the carrier if network access is required. Configure the operating system and device drivers according to the selected carrier board and connected peripherals.

Recommendations

For stable operation, select a carrier board that matches the module’s pinout and provides appropriate power regulation, thermal management, and the external storage interface you plan to use. When deploying in industrial environments, prefer wired networking or certified external wireless modules and ensure proper shielding and grounding.
