In July of last year, SpacemiT introduced the SpacemiT K3 SoC. Subsequent system details and early benchmarks were provided in January. The company has now officially released the K3 Pico-ITX SBC, available through various distributors. Firefly has released its own K3 hardware with the AIBOX-K3, an industrial-grade RISC-V edge computing box.
The AIBOX-K3 Edge AI mini PC is powered by the SpacemIT Key Stone K3 octa-core processor, equipped with an integrated AI engine delivering up to 60 TOPS of compute performance, ideal for local LLM inference and edge AI applications.
