Jupiter
Introduction
Milk-V Jupiter, powered by the Spacemit K1/M1 SoC, is the world's first Mini ITX device to support both RVA22 and RVV1.0. This device integrates a standard PCIe connector, supporting common PCIe devices such as graphics cards, PCIe to SATA adapters, and network cards. It features dual Gigabit Ethernet interfaces, onboard Wi-Fi 6/BT 5.2, and supports NVMe SSDs, making it an ideal choice for an entry-level RISC-V desktop.
