EMBER ONE

Appearance

Community and Contributing ​

Ember One is a 256 Foundation project. The design is published. Review, bring-up notes, and corrections happen in public.

Where things happen ​

GitHub holds the design work. The forum is the conversation around that work. Telegram is the 256 Foundation's public group chat.

  • Design repository: bug reports with reproducible technical detail, KiCad file issues, pull requests, and formal design reviews. The link stays on the v6.1 branch until the revision is verified and released. See Design files.
  • USB-serial firmware: the RP2040 firmware.
  • Forum, including the Ember One category. The category is for the conversation listed below.
  • Telegram: the Foundation's public group chat.

The Ember One forum category ​

Use the category for:

  • Build questions and assembly help. Hand-building tips, sourcing components, and ASIC variant compatibility.
  • Hardware troubleshooting. Debugging boards, thermal problems, and power-supply setups.
  • Testing and benchmarking. Results, hashrate, and power draw.
  • Forks and derivatives. A spin on the design, or a question about the form factor or a different ASIC.
  • Roadmap and future ASIC variants. Which chips people want supported. A formal design proposal belongs as a GitHub issue.
  • Integration. Pairing Ember One with Libre Board, Mujina, and the rest of the open mining stack.

Contributing ​

You do not need a grant. The designs are published. Read them, build on them, and say what is wrong with them. Hardware review, bring-up experience, and BOM feedback are all useful.

Open an issue or a pull request on the design repository. For the words on this site, use the edit link at the bottom of a page, or the notes under Contributing to this site.

Contributing to this site ​

This site lives in its own repository and takes pull requests. The contributing guide covers the workflow. Every page ends with an edit link.

Supporting this work ​

Ember One is a project of the 256 Foundation, which builds open tools for Bitcoin mining across the stack: this hashboard, the Libre Board control board, and Mujina firmware. Ember One takes no donations of its own. To support the work, support the Foundation.
