The Module LLM Kit is a modular offline AI inference kit built around the Module LLM and Module13.2 LLM Mate. It brings large-language-model voice interaction, data communication, and host connectivity into a stackable M5Stack module design.
Based on the AX630C SoC, the Module LLM Kit provides 3.2 TOPS INT8 NPU performance, 4GB LPDDR4 memory, and 32GB eMMC storage. It can run built-in KWS, ASR, LLM, and TTS functions locally without relying on a cloud service, helping privacy-sensitive and network-limited projects keep voice and text processing on the device.
Notice: Before connecting the FPC cable, lift the connector latch first. After inserting the cable fully, press the latch down to secure it.
Before connecting the Module LLM FPC cable, remove the device frame as recommended. The FPC connector is located under the SPK module, so remove the SPK module before operation.
Model replacement requires AXERA-specific model processing. Existing general models from the market cannot be used directly.

Yes. The Module LLM Kit is designed for local KWS, ASR, LLM, and TTS processing, so supported voice and language workflows can run on the device.
The module is listed with Qwen2.5-0.5B preinstalled, and the apt repository provides additional supported model packages.
No. The supported models use an AXERA-specific format and must be processed before they can run correctly on the hardware.
