Ember One: Open-Source Bitcoin Mining Hashboard

Powering Freedom Through Decentralized Innovation:
The Bitcoin mining landscape has long been dominated by closed, proprietary hardware from giants like Bitmain, leaving enthusiasts and advocates of Bitcoin’s open protocol with few options—until now. Building on the groundbreaking Bitaxe project, the Ember One takes open-source mining to the next level. This modular hashboard delivers ~100W of power and 2-4 TH/s of hashrate, offering a small but mighty step toward dismantling the proprietary mining empire and making Bitcoin accessible to all.

    Description

    Product Overview

    Ember One isn’t just a miner—it’s the foundation for a new era of open-source mining hardware. Designed as a standardized, customizable hashboard form factor, it empowers users with flexibility and control. Whether you’re running a single board or scaling up with multiple units, Ember One adapts to your needs, supporting ASIC chips from various manufacturers in future iterations. This is only the beginning—Ember One is the first of many designs set to evolve, boosting power and performance over time.
    Key Features
    • Performance: ~100W power draw, delivering 2-4 Terahashes per second using Bitmain S19 J-Pro series ASIC chips.
    • Modularity: Run one hashboard or several—your choice, with interchangeable components for maximum flexibility.
    • Input Voltage: Wide range of 12-24 VDC for easy integration into diverse setups.
    • Connectivity: USB communication between the control board and hashboards simplifies operation.
    • Open-Source Design: Fully GPL-licensed, including hardware component selection, PCB design, thermal management, and supporting documentation with hashboard interface specs.
    • User-Friendly: Carefully selected components prioritize ease of use and adaptability.

    Why Ember One?

    Bitcoin thrives on openness, yet its mining ecosystem has veered toward centralization and secrecy. Ember One challenges that trajectory by equipping users with a powerful, discrete tool to mine Bitcoin anonymously on its public blockchain—arguably the best way to secure financial freedom. Beyond personal empowerment, Ember One lays the groundwork for a broader, community-driven mining ecosystem, integrating ASIC chips from multiple manufacturers and inspiring further innovation.

    What’s Included

    • Deliverable: A validated, open-source hashboard design (~100W, 2-4 TH/s), complete with detailed documentation and interface specifications.
    • Scope: Focuses on hardware—PCB, thermal design, and component selection. (Firmware, enclosures, manufacturing, and support are excluded and left to the community or future phases.)
    • Timeline: Developed in just six months by a dedicated team of one project manager and up to two engineers.

    The Future Starts Here

    Ember One isn’t just a product—it’s a movement. With its open design, it invites developers, tinkerers, and miners to integrate, adapt, and build upon it. In six months, this grant-funded project delivers a validated hashboard ready to spark broader development, aligning with The 256 Foundation’s mission to benefit the public and secure Bitcoin’s decentralized promise.
