The Milk-V Jupiter is a mini ITX computer motherboard that combines an octa-core RISC-V processor with up to 16GB of onboard LPDDR4x memory, support for eMMC and PCIe NVMe storage, and a PCIe x8 expansion slot.
It’s the latest in a line of RISC-V products from Milk-V, and it looks like one of the most versatile to date, with a wide range of expansion options and a form factor that should allow you to place the board in a number of existing cases designed for mini ITX boards.
The Jupiter board measures 170 x 170mm (6.7″ x 6.7″) and features a SpacemiT K1 or M1 processor with eight SpacemiT X60 CPU cores based on RISC-V architecture, 819 MHz Imagination BXE-2-32 graphics, and support for up to 2 TOPS of AI performance.
That’s the same processor powering the MUSE Book and DC Roma II laptops, as well as smaller single-board computers like the Banana Pi BPI-F3 and SpacemiT Muse Pi.
Milk-V says the board will bee available with 4GB, 8GB, or 16GB of LPDDR4x memory soldered to the mainboard. Storage options include an M.2 2280 slot with support for PCIe 2.0 x2 storage, an eMMC connector for an optional flash storage module, and a microSD card reader for removable storage.
The company notes you could also use an M.2 to SATA adapter to add support for SATA hard drives or SSDs. And the board’s PCIe x8 slot supports 2-lane PCIe 2.0 connections allowing you to connect accessories like an SSD or a graphics card (although since PCIe 2.0 data transfer speeds top out at 500MB/s, you’ll most likely be limited to older/slower SSDs and GPUs).
The Milk-V Jupiter also features support for WiFi 6 and Bluetooth 5.2 wireless connections and has a set of ports that includes:
- 1 x USB 2.0 Type-C
- 2 x USB 3.0 Type-A ports
- 2 x USB 2.0 Type-A ports
- 1 x HDMI (up to 1920 x 1440 pixels @ 60 Hz)
- 2 x Gigabit Ethernet
- 1 x 3.5mm headphone
- 1 x 3.5mm microphone
- 1 x 12V DC power input
There are also front headers that can be used to add up to two more USB 3.0 ports and two more USB 2.0 ports. The front panel header also supports power and reset buttons and status and power LED lights.
Other features include a 24-pin ATX power supply interface, an RTC socket for a CR1220 battery, a PWM fan connector, and there’s also support for an optional Power over Ethernet module and SATA power connectors.
Milk-V hasn’t announced pricing or availability yet, but the company has links on its website that customers in China will be able to use to buy the mini ITX board from JD or Tabao once it’s available. There’s no word on if or when the Milk-V Jupiter will be available to customers outside of China.

CR1022 seems like a silly choice when almost every other board uses CR2032. SATA power for what. Very attractive price. I have one on order and it just shipped. Hoping the GPU support in the PCIe is sorted out for an recent AMD dGPU going into it. Looking forward to more powerfull RISC-V mainboards capable of desktop/workstation duties.

Imagination Graphics – Doesn’t that still require binary blobs, for royalty / license-free (exempli gratia, “not stolen”) drivers?
Weirdness. The fan connector could just as well be a typical 4-pin, and the battery could be a CR2032. And no, the PCIe slot being only PCIe 2 doesn’t limit you to older cards. That’s a silly claim to make. Remember, PCIe is backwards compatible. Sure, the bandwidth is limited and you may not get the most out of what you plug in but it should work.
This is interesting, but a single hdmi port with fairly low resolution doesn’t pair too well with that PCIe port that is also pretty limited.
I’m sure it has its uses though.
Waiting for the milk-v oasis…
