ArmSoM Sige6 Allwinner A733 SBC Packs 3 TOPS AI and LPDDR5 Memory

ArmSoM Sige6 Allwinner A733 SBC

The Sige6 Allwinner A733 SBC from ArmSoM combines an octa-core Allwinner A733 processor with AI acceleration, high-speed memory, wireless connectivity, and extensive I/O in a compact single-board computer. The SoC pairs two Arm Cortex-A76 cores running at up to 2.0GHz with six Cortex-A55 cores reaching 1.8GHz, while its 12nm architecture targets a balance between performance and power efficiency.

The board integrates a 3 TOPS NPU and Imagination BXM-4-64 MC1 GPU, giving developers hardware acceleration for AI workloads and graphics-intensive applications. It supports up to 16GB of LPDDR5 RAM, up to 128GB of eMMC storage, Wi-Fi 6, Bluetooth 5.4, and 4K video processing. ArmSoM positions the Sige6 for edge computing, AI, ARM PCs, intelligent NVRs, cloud applications, VR/AR, and other embedded workloads.

We previously covered the Orange Pi 4 Pro SBC, which features the Allwinner A733 SoC, a 3 TOPS NPU, and LPDDR5 RAM. The ArmSoM Sige6 offers a very similar hardware configuration, while the Orange Pi 4 Pro adds Bluetooth 5.4 and USB 3.1 connectivity. Feel free to check out our previous coverage for a closer look.

Sige6 ports and specifications

The Sige6 supports Debian Linux and Android 13, with Armbian available as a third-party option. ArmSoM provides an Allwinner SDK for Linux development, allowing users to build Debian-based images and separately compile components such as U-Boot, the Linux kernel, and root filesystems. Developers can also access interfaces such as GPIO, Bluetooth, Wi-Fi, camera, audio, RTC, and fan control through the Linux environment. The board supports both eMMC and MicroSD boot options, while SSH and serial interfaces provide convenient headless development and debugging. More details available on the documentation page.

Sige6 back side specifications

ArmSoM offers the Sige6 through its online sales channels. The exact purchase price depends on the selected RAM and eMMC configuration. ArmSoM states that it plans to produce the Sige6 through at least January 2036, making the board suitable for projects that require long-term hardware availability.
