Imagine you need a tiny computer that can run AI, handle 4K video, and still fit in a pocket-size case. The Sipeed K3 Pico-ITX SpacemiT 8-core RISC-V, 32GB Single Board Computer (SBC) gives you that power in a 100 86 mm board. Hobbyists, developers, and small manufacturers often struggle with slow, bulky PCs that cannot be placed inside custom enclosures. This board solves that problem by delivering desktop-grade performance in a compact, fan-cooled package.

When a project needs fast processing, AI inference, and high-resolution display but has limited space, the lack of a suitable board can delay development and increase cost. This matters because every extra inch of hardware adds weight, power draw, and design complexity. The Sipeed solution packs an 8-core RISC-V CPU up to 2.4 GHz, 32 GB LPDDR5 memory, and a powerful GPU into a Pico-ITX Plus form factor. It also offers gigabit Ethernet, 10 GbE, Wi-Fi 6, and multiple USB ports, giving you all the connectivity you need without a separate motherboard.
