Radxa's next single-board computer puts a Qualcomm Dragonwing Q-6690 onto a footprint roughly matching the Cubie A5E, which measures 65 x 56 mm (2.56 x 2.2 inches). The Dragon Q5E carries dual 2.5 GbE ports, HDMI out, USB Type-A and Type-C, and a 40-pin GPIO header, with optional Power over Ethernet and MIPI-CSI and MIPI-DSI connectors apparently routed to the underside of the PCB.
The Q-6690 is an industrial-tier Snapdragon variant with eight Kryo cores clocked up to 2.9 GHz, a 1.15 GHz Adreno GPU, and a Hexagon NPU rated at 6 TOPS. Wireless covers WiFi 7 and Bluetooth 6, and the SoC includes an integrated UHF RFID reader, an unusual inclusion for an SBC and one that opens up asset-tracking and inventory builds without a separate radio module. As CNX Software notes, Radxa's diagram also references PCIe Gen 3, though that link is likely consumed by the dual Ethernet controllers rather than exposed to users.
Memory is the spec sheet's biggest puzzle. Radxa lists configurations up to 16GB of LPDDR5-6400, while Qualcomm's own product page caps the Q-6690 at 3GB of LPDDR5-3200. One side has the numbers wrong, and Radxa hasn't published a full datasheet to settle it.
For Linux users, Qualcomm's recent Snapdragon platforms have been landing mainline support piece by piece, though Dragonwing-class chips still lean heavily on vendor kernel trees. Radxa has confirmed it will ship Debian-based Radxa OS and Ubuntu images for the Q5E, making those the practical first-boot options well ahead of stock upstream Debian or Fedora boots working cleanly. The Adreno side benefits from the open-source Freedreno and Turnip Mesa drivers, which already cover several Snapdragon generations and are the most plausible path to a usable desktop or GPU-accelerated workload on the Q5E once kernel support catches up.
Pricing and a ship date have not been announced. The Q5E was introduced alongside the larger Dragon Q8B SBC and Radxa's new DragonStation and DragonBay NAS systems, and it is the smallest of the group.
