Jednodeskový počítač ALLNET Radxa Zero 2 GB RAM 8 GB eMMC D2E8T s kolíkovou lištou (neosadenou) a externou anténou

ALLNET Radxa Zero D2E8T is a compact single-board computer designed for embedded systems, prototypes and space-constrained projects. It integrates 2 GB of RAM and 8 GB of onboard eMMC storage on a small form factor board. The module is supplied with an unsoldered pin header so users can solder and configure connectors to match their specific hardware needs. An external antenna is included to improve wireless reception for Wi‑Fi and Bluetooth connections.

Advantages

The small footprint and integrated eMMC storage reduce the need for external storage devices and simplify deployment in tight enclosures. The unsoldered pin header offers flexibility for custom wiring and connector choices, enabling clean, application-specific builds. The included external antenna enhances wireless reliability in environments with variable signal strength. The combination of low power consumption and compact size makes the board suitable for always-on or battery-powered devices.

Suitable for

• Embedded systems and industrial controllers with limited space
• IoT gateways, sensors and home automation hubs
• Prototype development and hardware proof-of-concept
• Compact media players and digital signage
• Education projects and maker applications

Key specifications

• Memory: 2 GB RAM
• Storage: 8 GB onboard eMMC
• Form factor: ultra-compact single-board module
• Connectivity: wireless with external antenna (Wi‑Fi/Bluetooth support)
• Expansion: unsoldered pin header for GPIO and peripheral connections
• Power: low-power design suitable for continuous operation

How to use

Prepare the board by soldering the supplied pin header according to your application’s connector layout, ensuring correct orientation and secure solder joints. Attach the external antenna to the antenna connector and position it for optimal signal reception. Load a compatible operating system image to the onboard eMMC or boot from a supported external medium if needed. Connect required peripherals such as power, display, input devices or sensors via the soldered headers and available ports, and configure network and system settings through standard OS tools.

Recommendations

When soldering the pin header, use appropriate ESD precautions and a temperature-controlled soldering iron to avoid heat damage. Place the board in a ventilated enclosure and route the external antenna to a location with minimal obstructions for best wireless performance. Regularly update firmware and software to maintain security and network stability.
