README
README.mdemberOne/00
A 100W open source ASIC Bitcoin mining hashboard.
- Wide 12-24VDC input voltage.
- Separate, USB connected control board required.
- Firmware support coming soon in Mujina Firmware
- Initial testing emberOne firmware support (hacked into) PiAxe/Pyminer fork
- Firmware for the onboard RP2040 usbserial converter: https://github.com/256-Foundation/emberone-usbserial-fw
The emberOne/00 is based on the BM1362 from the Bitmain Antminer S19j Pro. It should reach about 3.5 TH/s
Building
The emberOne/00 can be hand built. It's difficult, but you can do it with mininimal equipment and patience. Check out these assembly tips
ASICs
The emberOne/00 uses the Bitmain BM1362 chips from the S19j Pro. Make sure to use the BM1362AA, AB, AC or AD variants. It's possible that the BM1362AI, and BD variants could work, but they are untested. BM1362AJ and AK variants WILL NOT work.
Hacking
emberOne design files are built using the incredible, FOSS PCB CAD software KiCad. Please fork, hack and release!

Questions
How big is the Emberone PCB?
It measures 128 × 128 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Emberone use?
395 parts, built around the RP2040, TMP1075D, DS4432U+ and SK6812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Emberone KiCad files?
From the 256foundation/emberone00-pcb repository on GitHub, at the commit this page was made from: the board is emberone.kicad_pcb and its schematic asic-3up-0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Emberone design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
