Radxa Cubie A7A is a powerful SBC based on Allwinner A733 Cortex-A76/A55 AI SoC with up to 16GB RAM

Radxa Cubie A7A is a single board computer (SBC) powered by an Allwinner A733 octa-core Cortex-A76/A55 SoC with a 3 TOPS AI accelerator and up to 16GB LPDDR5 memory.

Radxa came back to the Allwinner SoC family after the silicon vendor committed to improving open-source support, starting with the Radxa Cubie A5E SBC powered by an Allwinner A527/T527 SoC. But this was only the start, and we were promised a more powerful Allwinner A733 SBC before moving to the Allwinner A838 down the road. The Allwinner A733 board is now available. Meet the Radxa Cubie A7A.

Radxa has posted some basic documentation on the product page, including a product brief, PDF schematics, a components placement map, and 3D drawings. With regards to software, the linux-sunxi website points to Radxa BSP with Linux 5.15 and Allwinner Tina SDK 1.4.6. However, Radxa told CNX Software that a Debian 11 with Linux 5.15 will be released in the next few hours/days, and support for Linux 6.6 and mainline U-boot is being worked on. We were also told that all Radxa OS features are being ported to the Allwinner platform/SDK.

Radxa Cubie A7A board is now available on AliExpress (link may not show with an Adblocker), starting at $35.74 with 2GB RAM and up to $66.38 with 12GB RAM. I’ve also been told you can chat with them on AliExpress to get a $10 discount coupon sponsored by Allwinner, bringing the price down to as low as about $25 plus shipping.
