Single-board computer ALLNET Radxa Zero 4GB RAM 16GB eMMC D4E16T con antenna esterna, pin header non montato

ALLNET Radxa Zero with 4 GB RAM and 16 GB eMMC (model D4E16T) is a compact single-board computer designed for space-constrained embedded applications and development. The board provides onboard flash storage and a dedicated connector for an external antenna to improve Wi-Fi/Bluetooth reception. The pin header is supplied unmounted, allowing users to solder a header of their choice or integrate the board into custom enclosures and compact housings.

Advantages

The small form factor and 4 GB of system memory enable multitasking on a tiny platform while the onboard 16 GB eMMC provides reliable local storage without the need for an external SD card. An external antenna connector helps achieve better wireless range and signal stability in challenging environments. The unmounted pin header gives flexibility for custom configurations, low-profile installations, or direct soldering to carrier boards.

Suitable for

• Embedded systems and compact industrial controllers
• Home media players and lightweight media servers
• IoT gateways, sensors aggregation and edge devices
• Software development, prototyping and learning platforms
• Custom enclosures where low profile or tailored connectors are required

Key specifications

• System memory: 4 GB RAM
• Internal storage: 16 GB eMMC
• External antenna connector for improved wireless reception
• Pin header: supplied unmounted for custom soldering or enclosure use
• Compact single-board computer form factor suitable for tight spaces

How to use

Prepare the ALLNET Radxa Zero for your project by soldering a compatible pin header or connecting the board directly to a carrier or custom PCB. Install a supported operating system image onto the onboard eMMC or boot from an external storage device if preferred. Connect the external antenna to the designated connector to improve Wi‑Fi/Bluetooth performance, and attach necessary peripherals such as power supply, network interfaces, display, and input devices depending on the use case.

Recommendations

Handle the board on an anti-static surface during assembly, and verify antenna connector compatibility before attaching an external antenna. For sustained performance in enclosed installations, provide adequate ventilation and consider using a heat spreader or passive cooling if the board operates under heavy load for extended periods.
