Single-board computer ALLNET Radxa Zero 4GB RAM 32GB storage D4E32H with onboard antenna

ALLNET Radxa Zero 4GB RAM 32GB storage D4E32H with onboard antenna is a compact single-board computer designed for space-constrained embedded projects and prototyping. It integrates 4 GB of system memory and 32 GB of local flash storage in a very small footprint and includes an onboard antenna for improved wireless connectivity. The board supports a range of lightweight server, controller and multimedia applications where low power consumption and minimal size are important.

Advantages

The small form factor and integrated antenna reduce the need for external components, making this single-board computer suitable for tight enclosures and portable devices. With 4 GB of RAM it can handle multiple concurrent lightweight processes and simple multitasking, while the 32 GB of onboard storage provides immediate local space for operating systems and application data without requiring an external drive. The included antenna improves wireless reception for networked applications and IoT use cases, and the overall design focuses on reliable basic performance with a low thermal profile.

Suitable for

• Embedded systems and compact industrial controllers
• IoT gateways and wireless sensor hubs
• Home media players and lightweight streaming devices
• Prototyping and development boards for software testing
• Networked microservices and small local servers

Key specifications

• System memory: 4 GB RAM
• Internal storage: 32 GB onboard flash
• Wireless: integrated onboard antenna for Wi‑Fi/Bluetooth connectivity
• Form factor: compact single-board design suitable for tight enclosures
• Power: low-power operation appropriate for battery-backed or always-on deployments

How to use

Install a compatible operating system image to the onboard storage or boot from network/USB when supported. Mount the board inside an enclosure ensuring the antenna has adequate clearance for optimal signal reception. Connect required peripherals such as power, display, network, and input devices according to the project needs. Configure network settings and install necessary software packages for server, media playback, or IoT applications. Monitor thermal conditions during sustained heavy load and provide passive or active cooling if the installation environment requires it.

Recommendations

Place the board so the onboard antenna faces an open area and avoid metal shielding that could block wireless signals. For reliable operation, use a stable power supply that meets the board's voltage and current requirements, and perform regular software updates and backups of important data stored on the onboard flash.
