On the software side, Radxa provides Android 13 and Debian Linux (Radxa OS) support, along with a hardware access/control library for Linux/Android. You’ll find OS images and other resources to get started on the documentation website. The RISC-V core runs FreeRTOS, but I could not find any development resources.
I was also told they ran OpenClaw personal AI assistant on the Radxa A7S SBC on a Debian 13 server image with Linux 6.6 and u-boot 2026. The agent can execute commands on the local hardware and control the SBC hardware interfaces. It’s not specific to that board, and they also tried it on RK3588 and CIX P1 boards. The company also noted that Armbian support for the A7S is coming soon.
I find it interesting that it’s one of the first non-headless boards that relies exclusively on a USB-C port to provide video output instead of the more traditional HDMI port or MIPI DSI connector.
The Cubie A7S SBC can be purchased on AliExpress for $28.82 and up in 4GB, 6GB, or 8GB RAM configurations. Alternatively, it’s also listed on Arace for $25 to $35. Further information may also be found on the product page.

“I find it interesting that it’s one of the first non-headless boards that relies exclusively on a USB-C port to provide video output”
Good: lets get rid and phase out that HDMI junk
Bad: Imagination GPU
Yeah, until you realize like me that this usbc-alt only does 16:9 resolutions at 60hz on the rk3588, with the closed Rockchip kernel only. In 2026, yayyyy. “Just get a n100” is still the best answer tbh.
“…and a 4-pin MIPI CSI camera…”
I think it should be 4-lane, I got slightly confused reading that at first.
on the photo it’s written 4-lane, but also “FAN connector” 🙂
On Aliexpress: €30,19 for EU, including EU VAT
It’s not as easy like you make it sound as there is nO unified VAT in the EU and typical standard rates range somewhere from 15 up to 27% value added(?) tax.
It might be useful to tell how much VAT is actually contained in the price of 30,19€ otherwise their is no use in your post

TomCubie, after 3 boards and 1 year, where are Radxa patches and where is the RAM controller documentation needed for booting your boards?
OK, above 30$ for a board of which Radxa will spend 0$ on upstream/mainline, expecting unpaid enthusiast to do it, while Radxa LIES, how they are working on it.
Oh yes I forgot, they spend for ads on cnx-software but not on upstream/mainline 🙂

“Out of stock” on both Arace and Aliexpress …
And still out of stock on Ali. Annoying. Says something about the quality of the suppliers.
These kind of posts are dumb if the board is 99% of the time out of stock.
It is starting to be tiring, SO tiring. For every single board announced here, out of stock all the time.
If these companies create stuff in batches of 100 units per month, it’s stupid to even pay attention on them.
well, maybe they run out of stock BECAUSE they’re advertised here.
I think Radxa also set their AliExpress store to holiday mode for Chinese New Year. The link to AliExpress returns a 404 error today. I’ll remove it if it’s still the case after the holidays.
Chinese New Year … 17 feb – 3 march. So we’ll see 4 march the result: available or not, and for what price.
