Radxa Dragon Q6A - A Qualcomm QCS6490 Edge AI SBC with GbE, WiFi 6, three camera connectors - CNX Software (2025)

Radxa Dragon Q6A is an upcoming credit card-sized SBC powered by a Qualcomm QCS6490 octa-core SoC with a 12 TOPS AI accelerator, up to 16GB LPDDR5 memory, and the usual ports found on Raspberry Pi-like single board computers such as gigabit Ethernet, four USB ports, HDMI video output, and a 40-pin GPIO header.

The board will also feature an M.2 Key-M socket for SSD storage, a WiFi 6 and Bluetooth 5.4 wireless module, a MIPI DSI display interface, three MIPI CSI connectors, a connector for an eMMC or UFS flash module, a microphone input connector, and an RTC battery connector.

Yocto Linux, Ubuntu, and Android operating systems will be supported (I can also see Windows in the first illustration), and the board targets robotics, industrial automation, AI boxes, smart cities, etc.. We have limited information right now, since the board is not listed on the Radxa website. Of note, it’s like a smaller version of the RUBIK Pi 3 SBC, also based on QCS6490, but in a Pico-ITX form factor. The QCS6490 SoC found in the Dragon Q6A is also basically the same as the QCM6490 powering the Fairphone 5, just without a 5G modem.

I got all my information for the new Radxa board on Weixin in Chinese, as Qualcomm has launched a developer contest with prizes of up to 30,000 CNY for the best projects leveraging Qualcomm DragonWing processor. Another good news is that Radxa is not the only company making Qualcomm SBC, and there’s a list of QCS6490 or QCS8550 boards that are recommended for the contest.

Thanks to Paul for the tip.
