Thundercomm TurboX C7790: A 24-TOPS Qualcomm Dragonwing Edge-AI Dev Kit
Thundercomm's TurboX C7790, detailed June 5, 2026, is a 4nm Qualcomm Dragonwing edge-AI development kit with a 24-TOPS NPU, 12GB LPDDR5X, and full Android and Linux BSPs.
A Well-Stocked Edge-AI Kit for Builders
On June 5, 2026, Thundercomm's TurboX C7790 development kit got a detailed write-up, and it is a genuinely appealing platform for anyone building on-device AI. At its heart is Qualcomm's new 4nm Dragonwing Q-7790 (CQ7790S) system-on-chip, and the kit is set up so makers and product teams can go from unboxing to running local inference without fighting the toolchain. The headline figure is a 24 TOPS (INT8) NPU — enough to run real computer-vision and edge-AI workloads directly on the board instead of shipping data off to the cloud.
Dragonwing Q-7790 Specs and I/O
The Dragonwing Q-7790 pairs an octa-core Kryo CPU — one Gold+ core at 2.8 GHz, four Gold cores at 2.4 GHz, and three Silver cores at 1.8 GHz — with an Adreno 722 GPU. The system-on-module ships with 12GB of LPDDR5X RAM and 128GB of flash, a healthy allocation for multi-camera AI work. The carrier board is where the C7790 earns its keep for prototyping: dual 1GbE, four USB 3.0 Type-A ports, a USB 3.1 Type-C port, two HDMI outputs, DisplayPort over USB-C, and MIPI DSI. A triple ISP can drive three 21MP cameras and handle 4K120 AV1 and H.265 decode, which makes this a strong base for AI cameras and video-heavy edge devices.
Priced and Provisioned for Real Projects
At $1,499, the kit is positioned for serious development rather than impulse tinkering, and it comes stocked accordingly: a Sony IMX577 camera, speakers, cables, and a 12V adapter are in the box. Critically for a single-board-computer-class platform, Thundercomm ships full Android and Linux board support packages with OTA update support, so teams can pick the OS that fits their product and keep devices current in the field. A wide -30°C to +75°C operating range signals that this is built with industrial and outdoor deployments in mind, not just a bench demo.
Where the C7790 Fits
The target applications read like a tour of modern edge computing: AI cameras, video conferencing endpoints, robotics, and edge-AI gateways. With 24 TOPS of local inference, triple-camera support, and proper thermal headroom, the TurboX C7790 is a capable foundation for the kind of standalone AI boxes our mini-computer readers love — devices that think at the edge instead of phoning home. For developers who want a documented, well-supported on-ramp to Qualcomm's latest edge silicon, this is an easy kit to recommend keeping an eye on.
