AI-8850 LLM Accleration M.2 Module AX8850 (M5-AI-001) NGFF M.2 M-KEY 2242

LLM‑8850 Card is an M.2 M-KEY 2242 AI acceleration card designed for edge devices, combining a compact 42 mm form factor with the Axera AX8850 SoC delivering 24 TOPS @ INT8 performance. It enables host devices such as Raspberry Pi 5, RK3588, and x86 PCs to easily expand multimodal large-model and video analysis capabilities with a simple plug‑and‑play design. The card is equipped with an active cooling system featuring a micro turbine fan and aluminum alloy CNC fins, with fan speed intelligently controlled by the onboard EC based on temperature–current curves. Even under long‑term full load, it can maintain stable low temperatures to prevent thermal degradation inside enclosed cases.

The onboard DCDC + PMIC power chain is managed in real time by the EC to achieve “power on demand, cooling on demand,” greatly improving overall system stability. Supports AXCL Runtime, with C / Python APIs enabling one-click deployment of mainstream CNN, Transformer, LLM, and multimodal models such as YOLO‑v8/v9, CLIP, Whisper, Llama 3.2, Gemma 2, Qwen 2.5; and utilizes the AX8850’s VPU hardware pipeline for H.264/H.265 8K encoding/decoding with simultaneous encode-decode transcoding acceleration and scaling/cropping, bridging AI and video stream processing. Host devices can directly invoke the hardware video codec via ffmpeg.
