M5Stack AI-8850 LLM Accelerator M.2 Kit

The M5Stack LLM-8850 AI Accelerator Kit adds up to 24 TOPS of AI performance to a Raspberry Pi 5 via PCIe, with active cooling and a compact M.2 design for edge computing projects - with 4GB or 8GB RAM. The M5Stack LLM-8850 AI Accelerator Kit for Raspberry Pi 5 is a compact edge AI solution designed to bring high-performance inference and video processing to embedded systems. The kit includes the LLM-8850 Card AI accelerator and a matching HAT adapter board. At its core, the accelerator card is built around the Axera AX8850 SoC and uses an M.2 M-Key 2242 form factor , delivering up to 24 TOPS (INT8) of compute performance . This makes it well suited for demanding workloads such as multimodal large-model inference and video analytics, all within a small footprint. To maintain performance under sustained load, the card features an active cooling system combining a micro blower fan with a CNC aluminium fin heatsink. Fan speed is intelligently controlled by an onboard EC, adjusting based on a temperature–current curve to keep temperatures stable. This helps prevent thermal throttling, even during long periods of heavy use or when installed in enclosed spaces. The included LLM-8850…
