Radxa Zero 3W/3E

Radxa Zero 3W and Radxa Zero 3E are compact SBCs commonly used as OpenIPC FPV ground-station hardware. Use this page for board-level notes, image choices, enclosure links, and related hardware resources.

For the practical WFB-NG setup flow, see Ground Station on Radxa Zero 3W.

Radxa Zero 3W/3E works well for a dedicated OpenIPC receiver when you want:

  • HDMI output for goggles or a monitor;
  • USB Wi-Fi adapters for WFB-NG reception;
  • DVR and media-server features on the ground station;
  • a small board that can be mounted in a custom enclosure.

Use at least 2 GB RAM, with 4 GB preferred. Use at least 8 GB eMMC or SD storage, with 16 GB preferred for DVR and easier updates.

Firmware Image Options

Use the latest OpenIPC SBC Ground Station release page as the main entry point for Radxa Zero 3 firmware. For current Buildroot images, follow the Buildroot Edition link to the buildroot-snapshot release and use the radxa_zero3_* files.

Older Stock Edition images are still linked from the same release page for existing installations, including zero3w-v1.9.9, zero3w-v2.0.0-beta2, and zero3w-apfpv-v0.0.1.

  • Wi-Fi adapter hot-plug handling;
  • WFB key storage and configuration partitions;
