M5Stack LLM‑8850 card is an M.2 M-Key 2242 AI acceleration module powered by an Axera AX8850 SoC delivering 24 TOPS ( INT8) of performance, and suitable for host devices such as Raspberry Pi 5, Rockchip RK3588 SBCs, and even x86 PCs like mini PCs with a spare M.2 Key-M socket. It is also equipped with an active cooling system to maintain stable temperatures and prevent thermal degradation inside enclosures. Based on the arguably flawed TOPS number, it looks like a potential competitor to the 26 TOPS Hailo-8 AI accelerator. However, the latter is optimized for computer vision applications, and for tasks like LLMs, the Axera 8850 will be vastly superior. M5Stack sells the Axera AX8850 M.2 module for $99 on AliExpress and its own online store.
