M5Stack has unveiled the AI Pyramid Computing Box, a Linux mini PC with an unconventional pyramidal enclosure powered by the Axera AX8850 SoC. The octa-core Cortex-A55 processor runs at 1.7 GHz and pairs with a 24 TOPS NPU designed for edge AI workloads like vision gateways, smart security systems, and local photo management. The device measures 14.5 x 10.5 x 6.2 cm (5.7 x 4.1 x 2.4 inches) and weighs about 195 grams (6.9 oz).
Two variants are available: the base model with 4GB LPDDR4x RAM split between Linux and the NPU, and a Pro version with 8GB. Both include 32GB eMMC storage, a microSD slot, dual Gigabit Ethernet ports, four USB 3.0 ports, and two USB-C connections. The video subsystem handles 8K encoding at 30 fps and decoding at 60 fps, with support for 16 simultaneous 1080p streams. The base model offers dual HDMI outputs, while the Pro trades one output for an HDMI input capable of 4K60 capture. A four-microphone array and built-in speaker round out the I/O, alongside an STM32 coprocessor managing an OLED status display and 48 RGB LEDs.
M5Stack positions this as a turnkey edge AI platform rather than a development board. Documentation covers integration with Home Assistant, Frigate NVR, Immich for smart photo albums, and voice processing tools like CosyVoice and sherpa-onnx. Native AXCL support enables deployment of CNN, Transformer, Whisper, Llama 3.2, Qwen 3, and InternVL3 models. The company already sells AX8850-based M.2 accelerator cards for Raspberry Pi 5, making the Pyramid a self-contained alternative requiring only a 27W USB-C power supply.
The 4GB model is available now for $200 (€185), with the 8GB Pro version priced at $250 (€230).
