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.
