Radxa has launched the Cubie A7S, a compact single-board computer measuring just 5.1 x 5.1 cm (2 x 2 inches) that packs the Allwinner A733 octa-core processor with up to 16GB of LPDDR5 memory. The board features a dual-core Cortex-A76 cluster running at 2.0 GHz paired with six Cortex-A55 efficiency cores at 1.8 GHz, plus a 200 MHz RISC-V real-time core running FreeRTOS. An optional 3 TOPS NPU handles AI workloads, while the Imagination BXM-4-64 GPU supports OpenGL ES 3.2, Vulkan 1.3, and hardware video decoding up to 8K.
Connectivity on this tiny board is surprisingly comprehensive. It includes Gigabit Ethernet, WiFi 6 with Bluetooth 5.4 via a Quectel module, two USB-C ports (one with DisplayPort Alt mode for 4K60 output), and a USB 2.0 Type-A port. Storage options include a microSD slot and up to 256GB of onboard eMMC. The 16-pin PCIe Gen3 x1 FFC connector maintains compatibility with Raspberry Pi 5 accessories, and a 4-lane MIPI CSI connector supports camera modules.
Radxa offers Android 13 and Debian Linux images for the board, with documentation and downloads available on their wiki. The company has demonstrated the board running OpenClaw, an open source personal AI assistant capable of executing commands and controlling hardware interfaces. Armbian support is reportedly coming soon.
The Cubie A7S is available now starting at around $25 (€23) for the 4GB model, with 6GB and 8GB configurations priced up to $35 (€32). More details can be found on Radxa's product page.
