ESWIN Computing, in collaboration with Canonical, has launched the EBC7702 Mini-DTX motherboard, a RISC-V development platform with ESWIN’s new EIC7702X dual-die RISC-V SoC. This board can be considered an upgrade from the previous EBC7700 SBC and is designed for more demanding AI and data processing tasks.
The motherboard features an 8-core 64-bit dual-die RISC-V CPU with an integrated AI accelerator delivering up to 40 TOPS (INT8) and 20 TFLOPS (FP16) performance. It supports up to 64GB LPDDR5 memory, 32GB onboard eMMC flash, and multiple storage interfaces, including M.2, SPI Flash, and MicroSD. Connectivity options include four Gigabit Ethernet ports, Wi-Fi, two HDMI outputs, two PCIe Gen3.0 x16 slots, USB 3.0/2.0 ports, and four fan headers. With support for AI, display, and camera modules, the board is designed for video analysis and edge AI workloads.

The EBC7702 Mini-DTX Mainboard comes with Ubuntu 24.04 LTS pre-installed, providing a stable Linux environment with long-term updates and security support. The prebuilt images provided by ESWIN Computing are also available on GitHub; you can follow the instructions there to install the software yourself.
In our last post about the EBC7700 SBC, we mentioned a possible issue with future Ubuntu versions. The same applies to the new EBC7702 Mini-DTX Mainboard. Ubuntu 25.10 and later will require the RVA23 profile with Vector and Hypervisor extensions, which the EIC7702X SoC with RV64GC cores does not have. This means the board will officially support only Ubuntu 24.04 LTS, and upgrades to newer Ubuntu versions may not be (easily) feasible.
This is not the first time we’ve seen a RISC-V motherboard using the Mini-DTX form factor. We notably saw the HiFive Premier P550 motherboard, which comes in the same form factor and uses the EIC7700X SoC found in the EBC7700 SBC.
According to Canonical’s official announcement, the ESWIN EBC7702 Mini-DTX RISC-V motherboard is not yet generally available for purchase but will be open for pre-orders soon. However, the motherboard is already offered on Amazon for $698.00 for the 32GB variant.

RV64GC … so no V = Vector. Pity.
$698 … that’s an “impressive” price.
> “System Memory – Up to ”
Up to what amount exactly?
Also the inter-core latency (between CPU cores) with this EBC7702 thing is ‘a bit’ on the high side: https://github.com/ThomasKaiser/sbc-bench/issues/125#issuecomment-3403544105
“a bit” 🙂 In the order of what you’d get on a pair of 8088.
Very intetesting but the price is horrible
This is more like it. 2 real pcie slots instead of some flimsy fakeout fpc ribbon makes this more useful for development than a tiny SBC. There is room for a nice modern AMD Radeon gpu and the extra slot for testing other misc cards to get working under RISC-V. Plus a replaceable processor just like an AMD motherboard, unlike the new Framework PC. It is nice to know the cpu can be upgraded later to the latest RISC-V extensions. RISC-V vendors are finally “getting” it -what users expect for a desktop. This is the most PC-like RISC-V board to date. Interesting to see RISC-V migrating from MCU to SBC and now into PC space. Hopefully this keeps trending in the right direction for future hardware.
I was thinking now in the line of a nas, with a PCIe -> SAS card and a PCIe 16 to 4 nvme card
Well unless you are porting the drivers yourself, that’s never going to happen.
The big GPU players might have that already, consider that they also make asic for big customers and data center, but they will never give a mere “gamer” the stuff they dedicate only for the multi-billion partnerships.
The big GPU players
– like AMD? Ever since linux kernel 6.10 those have been working for over a year on riscv

Working well that people all over able to play Steam games using box86 or felix86

See this is what hardware freedom looks like and real proof of how AMD is in actuality most friendly to open source. Compare to Nvidia acting so lordly over their stuff, people do not have to wait hand and foot or wait years and be held back to work on the boards they want with devices that was completely paid for.
What you said is partially true but honestly it’s just a very dump idea, to game on risc-v and arm. The problem is not just the GPUs, it’s in the cpu architecture, with every designer designing their own IPs or variants. It’s just extremely unpractical for the general market to “game” on it.
Sure you can use emulator to emulate everything, but what is the intention behind this? Performance? Efficiency?
These processors are ultimately purpose designed. They are not here to replace x86. (well except for Chinese, they have some funny politics)
Any new SBC, or any new boards, or computers should never come with 1 gigabit today. I would rather have a board with two 2.5 gigabit ports vs four 1 gigabit ports. OEMs need to stop using 1 gigabit ethernet, period. Considering the price difference to go from 1 gigabit to 2.5 gigabit is very small. Plus its not much of a difference to go from 2.5 gigabit to 5 gigabit. OEMs need to stop cheaping out their boards. Not to mention they should have added a 96 GB option as well.
> Any new SBC, or any new boards, or computers should never come with 1 gigabit today.
On vast majority of devices this would then mean to sacrifice one PCIe lane per Ethernet connection which would result in this board here not being able to provide the four lanes per PCIe slot.
With GbE it’s usually using the SoC’s internal GMAC/RGMII capabilities so all you need to add as device manufacturer is a cheap PHY while being able to use the precious PCIe lanes.
> they should have added a 96 GB option as well
Which no-one will buy since this SoC here only supports LPDDR and consumers always have a hard time to understand that a certain amount of ‘larger’ LPDDR memory results in way higher prices compared to a system equipped with DIMM slots.
On a DIMM eight rather cheap RAM chips of lower capacity are bundled together while with LPDDR and few channels you combine only a few chips of higher capacity that are way more expensive. And do 192 Gb LPDDR modules even exist today?
What a joke, please try to prove 96GB of LP5 is a viable option first. Calculate for me, let’s say the processor has 128 bit width for DDR. You are asking for 192Gb density per 32 bits.
And going from 1g ENET to say 2.5g ENET is vastly different, one is RGMII and one is SGMII or other 2.5g capable mac.
Your opinion here is completely useless and brainless. Please try to actually think, and not hop on some completely invalid gibberish bandwagon, it’s not the “OEMs”, it’s the processor.
[ thinking of an average usability of ~5yrs, (with soldered memory) it’s throwing away, about 19.2GB/a for a 96GB device? That’s {*}. *Please insert Your favorite word. (thx) ]
$698 for a dead-end board? Canonical has really screwed RV chip designers’ product lifecycles.
