Following the official launch of SpacemiT’s K3 Pico-ITX SBC and the mass production of the K3 chip, an Edge AI mini PC and a laptop motherboard for Framework 13 have been released. Adding to these, Firefly has introduced the CSC2-N48SPK3, a large 2U rack-mounted server built on multiple SpacemiT K3 SoCs designed to deliver RISC-V computing power to enterprise racks.
While consumer devices and modular laptops serve developers well, substantial server-side AI workloads demand stronger hardware. The CSC2-N48SPK3 meets this demand with up to 48 SpacemiT K3 RISC-V compute nodes. Each node features an octa-core X100 SoC providing up to 60 TOPS (Sparse) AI performance, up to 32GB LPDDR5 RAM, 128 GB UFS storage, and an optional NVMe SSD. Firefly uses a Rockchip RK3588 octa-core Arm processor as the main control node to manage all these nodes.
