The Radxa Cubie A7S Mini packs an unusually varied processor into a small board: the Allwinner A733 combines two Arm Cortex-A76 cores running up to 2.0GHz, six Arm Cortex-A55 cores up to 1.8GHz, and a single Alibaba RISC-V XuanTie E902 core up to 200MHz. Graphics run on an Imagination PowerVR BXM-4-64 GPU supporting OpenGL ES, OpenCL 3.0 and Vulkan 1.3, and a 3 TOPS NPU handles AI inference across INT4, INT8, INT16, FP16 and BF16 precision.
Memory is LPDDR5, offered in 4GB, 6GB, 8GB or 12GB configurations with a stated maximum of up to 16GB, which is a generous amount for a board this size and puts it closer to a compact desktop than a typical microcontroller-class device.
Video output uses a single USB-C port with DisplayPort Alt Mode, supporting up to 4Kp60, while a 4-lane MIPI CSI input handles camera modules. Encoding covers H.265/H.264 up to 4K@30fps, and decoding extends to H.265, VP9 and AVS2 up to 8K@24fps, which is a wide codec range for a board of this class. Networking includes Gigabit Ethernet plus onboard WiFi 6 and Bluetooth 5.4.
USB connectivity spans a USB-C 3.2 port, a separate USB-C 2.0 port and a USB-A 2.0 port, and an FPC connector exposes a PCIe 3.0 x1 lane for NVMe SSD expansion. Storage otherwise comes from optional eMMC up to 256GB and a microSD card slot. The board measures 51mm x 51mm and is powered over USB Type-C at 5V.
Developers building compact edge-AI devices, camera-based inference projects or small but capable Linux systems will get the most from the Cubie A7S Mini's NPU and wide codec support. If your project has no AI or video workload, a simpler and cheaper board may be a better match.
