The design is very similar to the Raspberry Pi 5, and accessories such as the active cooler, some Raspberry Pi HAT+, and Raspberry Pi cameras and displays may be compatible, provided these are supported by the software.
The announcement was just published on the Canonical website, so it’s as official as it can be. But then, I’m confused, as Ubuntu 25.10 and greater will require RVA23, itself mandating the RISC-V Vector (RVV) Extension that should be missing from an SoC with RV64GC cores. That would mean only Ubuntu 24.04 will be supported on the EBC77 SBC, and upgrades to newer versions will not be possible.
The EBC77 Series SBC was unveiled at the RISC-V Summit China 2025, which started on July 17, 2025 at ESWIN Computing and Canonical’s booth. The new quad-core RISC-V SBC sells for $149 on ESWIN’s Amazon online store or $168 with heatsink and USB-C cable.

Canonical have been very good about providing images for the RISC-V SBCs created so far. My guess is that they want Ubuntu closely associated with RISC-V.
And, if I have read it correctly, they haven’t actually said that they are planning to lay waste to the RISC-V boards that they’ve provided images for. 24.04 is LTS, so they could carry on supporting them.
What they seemed to be saying was that they were in line with other OS providers and with RISC-V International : RVA23 is the standard going forward.
Yes well whilst they provided some images, they lack graphics support on Milk-v Mars and looking at the ESWIN notes you login via serial console…….
oh! super thanks for the news!
Yeah, this isn’t really any different than most other (no RPI) SBC boards. They ship with a userland from one or two distributions (usually Debian-based) and never upgrade past that initial version. It’s an LTS so you get security fixes for a long time.
Most other SBC boards roll their own images. Here, the image is being provided by Canonical (Ubuntu’s developers) officially.

Check https://www.youtube.com/watch?v=IrFuTrclemw&t=440s – they’re talking about ’emulating’ RVV 1.0 on the internal DSP.
Thanks. That’s for the 7702, would that also work on the 7700X? Maybe…
It can be checked by compiling code with:
and running it on an EIC7700X board.
Is this the pi killer?
I think not, price will probably be double
N100-based minis are Pi killers
What about heat and power consumption?
Insignificant. I run Home Assistant on N100/16GB/512GB M.2 SSD @10% average CPU utilization @110F. And, it’s not a physical kludge like the Pi I used previously. The Pi-based system ran at about 108F, typically, with an add-on M.2 SSD. When the HA system “steps on the gas”, it leaves the Pi in the dust.
i went for RK3588 for HA since im running solar , like half the wattage at idle , ofc it doesnt make a difference 4W more or less in the long run vs having a proper software support like with intel
Its ubuntu server version only. I dont need a such small server. Eswin risc cpu needs fan and radiator. Iam courius how it will be cooling on small demensions EBC77
$149 Bare-board.
$168 Board with heatsink attached.
Definitely not cheap!
Can someone explain what’s the implication of Canonical providing an official Ubuntu image for this board? Does that mean it’ll have excellent (open-source?) software support? An OS that supports all the fancy peripherals in the chip (video codecs, vision engine, NPU, etc.)?
Based on previous images provided for RISC-V hardware, it does not mean full support for all features. Only a subset may be supported.
That’s disappointing. Seems like the Raspberry Pi ecosystem is still uncontested in terms of having non-bullshit software that’s easily accessible to hobbyists.
