In July 2025, Canonical officially announced that ESWIN Computing's EBC77 Series now supports Ubuntu 24.04 LTS. This SBC features a 64-bit OoO RISC-V CPU and an in-house developed NPU, making the RISC-V + Ubuntu + AI combination a notable highlight. However, detailed specifications for I/O, power, and other aspects remain unconfirmed in official primary sources, so additional research is needed before deployment.
On July 16, 2025, Canonical officially announced on their blog that ESWIN Computing's EBC77 Series now supports Ubuntu 24.04 LTS.
This SBC features a 64-bit OoO (Out-of-Order) RISC-V CPU and an in-house developed NPU, achieving the notable combination of RISC-V + Ubuntu + AI. It also includes high-speed LPDDR5 6400Mbps memory, suggesting a design focused on edge AI applications.
However, with the Canonical official article and ESWIN's official GitHub being the primary information sources, detailed specifications for I/O, power, and other aspects remain unconfirmed. Additional research is required when considering actual deployment.

RISC-V CPU + in-house NPU + Ubuntu 24.04 LTS is the defining combination of this SBC.
However, since detailed specifications essential for SBC selection—such as I/O, storage, and power—remain unconfirmed in official primary sources, the current assessment is limited to a news-level announcement that "a Ubuntu-compatible RISC-V SBC has been released."
Features
RISC-V CPU + NPU
The CPU is a 64-bit OoO (Out-of-Order) RISC-V CPU, and it also includes an NPU developed in-house by ESWIN Computing. The Canonical official article introduces this board with the premise of "RISC-V + AI inference."
However, specific CPU model numbers, core counts, and NPU computational performance (such as TOPS values) could not be confirmed in official primary sources. Benchmarking and competitive comparisons are currently difficult.
The combination of RISC-V architecture + Ubuntu itself is rare, making this a point of interest for developers who want to run a Linux desktop environment on architectures other than ARM.
Memory
The memory is LPDDR5 6400Mbps, providing high-speed memory bandwidth. While the capacity could not be confirmed in official primary sources, it is presumed to be a specification designed with edge AI applications in mind.
Boot and OS
Ubuntu 24.04 LTS images and installation instructions are provided on ESWIN's official GitHub (ebc7700-sbc-ubuntu). Official Ubuntu support through collaboration with Canonical is clearly stated, providing assurance for OS setup.
However, details about boot media (microSD, eMMC, NVMe, etc.) remain unconfirmed.
I/O and Expansion
The Canonical official article mentions "rich expansion interfaces," but specific specifications for GPIO, M.2, PCIe, and others remain unconfirmed.
Hands-on I/O evaluation will need to wait for official documentation expansion or the appearance of review articles.
Power and Thermal
Power input and cooling methods could not be confirmed in official primary sources. When deploying, we recommend checking updates on the official GitHub and forum information.
Appearance
The Canonical official article includes an image showing the full board view. While an overview of major chips and connector layouts can be confirmed, details of terminals and silkscreen are limited by image resolution.
Images of the board's underside and port faces could not be confirmed in official primary sources.
Summary
The ESWIN EBC77 Series is an SBC characterized by the combination of RISC-V CPU + in-house NPU + Ubuntu 24.04 LTS. With Canonical announcing it on their official blog, it can be said to be a product symbolizing the expansion of the RISC-V ecosystem.
It's suited for early adopters who want to try AI inference and development in a RISC-V + Ubuntu environment. It's not suited for cautious buyers who want to confirm detailed specifications before making a purchase decision. Currently, primary information on I/O, power, storage, and other aspects is lacking, making it difficult to assess practical operational viability.
For pricing and availability, we await information disclosure on official sites and sales channels.
