Radxa has just unveiled its latest powerful credit-card-sized single-board computer (SBC), the Cubie A7A, which re-marks the company’s return to Allwinner silicon with a potent edge AI proposition. It is a high-performing option for AI, edge computing, and embedded applications.
Radxa Cubie A7A SBC specifications
Equipped with the Allwinner A733 SoC, the module features a hybrid octa-core CPU architecture, comprising two Arm Cortex-A76 cores that reach up to 2.0 GHz, six Cortex-A55 cores that reach up to 1.79 GHz, and a dedicated RISC-V E902 real-time core for ultra-low-power tasks and secure system control.
Imagination’s BXM-4-64 MC1 GPU handles graphics, and AI acceleration is available via an optional integrated NPU delivering up to 3 TOPS at INT8 precision. Video processing supports high-resolution workflows with hardware-accelerated decoding of up to 8Kp24 and encoding of 4 K X 30 fps, handled by the onboard VPU.
Memory options range from 2 GB to a substantial 16 GB of LPDDR5 RAM at 4800 MT/s, complemented by versatile storage support including microSD, eMMC, UFS, and even NVMe modules. Connectivity is rich: dual-band Wi-Fi 6, Bluetooth 5.4, Gigabit Ethernet with optional PoE support; USB includes one USB 3.0 host port, three USB 2.0 host ports, and a USB 2.0 OTG Type-C interface.
Display and expansion capabilities are generous for an SBC of this size (85 × 56 mm): HDMI 2.0b, MIPI-DSI display, MIPI-CSI camera interface, a 40-pin GPIO header, and a PCIe Gen3 x1 FPC connector.
Software support appears promising, with Radxa offering a BSP based on Linux 5.15 and Tina SDK 1.4.6; mainstream operating system compatibility, Debian 11 images and mainline U-Boot are reportedly forthcoming.
You can check out my previously written SBCs, including the Banana Pi BPI-F4, the StarFive VisionFive 2 Lite, and others, for your reference.
The Radxa Cubie A7A is now available through online platforms such as AliExpress, with prices typically ranging from $30 to $66 depending on memory configuration. Early-bird buyers may access a $10 discount, bringing the cost as low as $25 plus shipping. Variations in price across retailers reflect memory options and promotional deals. You can find more information on the product page, along with the data sheet, schematic, and 3D drawings.
