¶ K3 Pico-ITX Introduction
The K3 Pico-ITX is an ultra-integrated mini AI single-board computer. Within a compact 2.5-inch form factor, it integrates 60 TOPS of general-purpose AI computing power, an 8-core RVA23 processor, and 8 intelligent computing cores. Its unified memory architecture allows for smooth deployment of large models with 30 billion parameters. Onboard UFS storage (3.4 times faster than eMMC) and a full-featured Type-C port (65W PD power supply + 4K DP display) enable a "one-line-to-use" experience. Dual M.2 expansion slots (including PCIe Gen3 x4) and a 10 Gigabit fiber optic port support high-speed storage and cluster deployment. Real-time core-to-core output of flexible I/O such as EtherCAT and CAN-FD meets microsecond-level motion control requirements. Its industrial-grade architecture, combined with the eDP display interface, helps industry customers quickly evaluate and integrate systems, accelerating the commercialization of AI edge computing and robotics.
