Milk-V Jupiter Announced: RISC-V ITX Desktop

Hot on the tails of its Ubuntu partnership, RISC-V-focused outfit Milk-V have announced its latest offering, the Milk-V Jupiter in an ITX form factor, intending to be your next low-power desktop.

There isn’t much to go on yet, so I’ll update this as and when information becomes available but let’s get to some speculation first, shall we?

In the teaser image they released above, you can see that we have a full-size PCI Express connector and this is arguably the most interesting connector on offer in this teaser. Support for devices slotting into that, however, is another matter.

My best guesstimates on what we have here:

  • 2x USB Type-A 3.0
  • 2x USB Type-A 2.0
  • microSD
  • 2x RJ45 (Hopefully 2.5Gb?)
  • HDMI
  • USB-C?
  • DC Power In
  • M.2 M-Key (Supporting up to 2280?)
  • 3.5mm Audio Jack


Some of those are educated guesses, for example, I’m being hopeful rather than confident that there are 2 of each USB Type-A as we’ll be rather limited on I/O if it’s only 1 of each.

2.5GbE on both RJ45 connections would be great and an M-Key M.2 slot for NVMe is lovely as it was a massive benefit to the StarFive VisionFive 2 in performance testing. If Milk-V intends for users to buy this as a desktop offering as opposed to a dev kit, storage is going to be very important.

Which SoC are we Getting?

There has been an awful lot of speculation on which RISC-V SoC we’re going to see in the Milk-V Jupiter, with the Eswin EIC7700, SpacemiT K1, and StarFive JH8100 all mentioned (among others) on various Reddit and WeChat posts. The Milk-V Oasis already comes with the Sophgo SSG2380 so I’d imagine they’ll go with something else on this. Hopefully.

Milk-V Jupiter Announced - RISC-V PC for Everyone

RISC-V PC for Everyone

It’s a big tagline, and I’m curious to see what the rest of the announcements give away.

As someone who’s been testing another ITX desktop replacement in the form of the Radxa ROCK 5 ITX (based, however, on the Rockchip RK3588 ARM SoC, not RISC-V) I’ve been slowly coming around to the idea of this form factor.

What I’ll be interested to see though, is what other I/O is on offer here. Will there be power available via a traditional ATX power supply? Will it take standard PC accessories such as CPU coolers (not that you’re likely to need them)? Will there be SATA connections available for storage?

I’ll keep my ears to the ground (otherwise known as bugging the poor Milk-V staff constantly) and as soon as I have additional information, I’ll update this article, so do keep checking back to stay up to date with how the Milk-V Jupiter is progressing.

In the meantime, I’ll get to benchmarking the Ubuntu-powered Milk-V Mars that recently landed on my doorstep!
