RISC-V single-board computers keep climbing the performance ladder, and the Milk-V Jupiter2 is the latest to push the envelope. Built around a SpacemiT K3 SoC with eight RVA23-compliant RISC-V cores, an Imagination BXM-4-64-MC1 GPU, and an NPU rated for up to 60 TOPS of AI performance, it represents a substantial leap over the K1-powered original Jupiter board.
The Jupiter2 measures 100 x 86mm (3.9 x 3.4 inches), a noticeable shrink from the mini-ITX form factor of its predecessor. That smaller footprint comes at the cost of the original's dedicated PCIe x8 slot, but the board still packs serious expansion options. There's an M.2 2280 slot wired for PCIe 3.0 x4 NVMe storage, a second M.2 2242/3042 slot (PCIe Gen 3 x2) that can host a cellular modem paired with the onboard nano SIM tray, plus WiFi 6 and Bluetooth 5.2 built in. Memory tops out at 32GB of LPDDR5-6400 soldered to the board, with up to 256GB of UFS storage available alongside the NVMe slot.
Networking is one of the standout upgrades. The board ships with both a 10 Gigabit SFP+ cage and a standard Gigabit Ethernet port, making it a credible option for home lab or edge networking workloads. Display and USB connectivity come courtesy of two USB 3.2 Gen 2 Type-C ports with DisplayPort Alt Mode (one of which doubles as a 65W USB-PD input), four USB 2.0 Type-A ports, and an embedded DisplayPort header. The package includes an aluminum enclosure with an integrated fan, plus headers for RTC battery, audio, an ATX power connector, and an I/O expansion bus for add-on modules.
On the software side, Milk-V lists support for Ubuntu 26.04, OpenHarmony 6.0, Fedora, Deepin, OpenKylin, and Bianbu 3.0, reflecting the growing distribution support for the RVA23 profile. That list has solid upstream grounding: Canonical formally partnered with SpacemiT to bring official Ubuntu 26.04 LTS support to K3-based platforms, and the underlying SpacemiT K3 SoC gained initial mainline Linux kernel support in Linux 7.0, with further peripheral enablement expected in Linux 7.1. Pre-orders are open starting at $300 (€275).
