Orange Pi Zero 4 SBC Packs Allwinner A733 SoC and 3 TOPS NPU

Orange Pi Zero 4

Orange Pi has introduced the Orange Pi Zero 4, a compact single-board computer (SBC) powered by the Allwinner A733 processor. The board combines an octa-core CPU, a 3 TOPS neural processing unit (NPU), integrated graphics, and support for up to 16GB of LPDDR5, LPDDR4X, or LPDDR4 memory. Measuring just 50 × 55mm, it targets embedded developers, makers, and engineers who need high processing performance in a small form factor.

The Orange Pi Zero 4 also offers Gigabit Ethernet, Wi-Fi 6, Bluetooth 5.4, and dual-display output through Mini HDMI 2.0 and USB Type-C. Its expansion interfaces support camera modules, high-speed peripherals, and general-purpose input/output (GPIO). These features make the board suitable for edge AI, IoT gateways, home servers, network-attached storage (NAS), and 4K smart TV box projects.

We previously covered the Orange Pi 4 Pro, which also features the Allwinner A733 SoC, a 3 TOPS NPU, and LPDDR5 memory. We also covered the ArmSoM Sige6, another Allwinner A733-based SBC with 3 TOPS AI performance and LPDDR5 memory.
